Sinan Kaya 5d32a66541 PCI/ACPI: Allow ACPI to be built without CONFIG_PCI set
We are compiling PCI code today for systems with ACPI and no PCI
device present. Remove the useless code and reduce the tight
dependency.

Bob Moore 4c1379d7bb ACPICA: Debug output: Add option to display method/object evaluation
Adds entry/exit messages for all objects that are evaluated.
Works for the kernel-level code as well as acpiexec. The "-eo"
flag enables acpiexec to display these messages.

The messages are very useful when debugging the flow of table
initialization.

Pull power management updates from Rafael Wysocki:
 "These make hibernation on 32-bit x86 systems work in all of the cases
  in which it works on 64-bit x86 ones, update the menu cpuidle governor
  and the "polling" state to make them more efficient, add more hardware
  support to cpufreq drivers and fix issues with some of them, fix a bug
  in the conservative cpufreq governor, fix the operating performance
  points (OPP) framework and make it more stable, update the devfreq
  subsystem to take changes in the APIs used by into account and clean
  up some things all over.

  Specifics:

   - Backport hibernation bug fixes from x86-64 to x86-32 and
     consolidate hibernation handling on x86 to allow 32-bit systems to
     work in all of the cases in which 64-bit ones work (Zhimin Gu, Chen
     Yu).

   - Fix hibernation documentation (Vladimir D. Seleznev).

   - Update the menu cpuidle governor to fix a couple of issues with it,
     make it more efficient in some cases and clean it up (Rafael
     Wysocki).

   - Rework the cpuidle polling state implementation to make it more
     efficient (Rafael Wysocki).

   - Clean up the cpuidle core somewhat (Fieah Lim).

   - Fix the cpufreq conservative governor to take policy limits into
     account properly in some cases (Rafael Wysocki).

   - Add support for retrieving guaranteed performance information to
     the ACPI CPPC library and make the intel_pstate driver use it to
     expose the CPU base frequency via sysfs on systems with the
     hardware-managed P-states (HWP) feature enabled (Srinivas
     Pandruvada).

   - Fix clang warning in the CPPC cpufreq driver (Nathan Chancellor).

   - Get rid of device_node.name printing from cpufreq (Rob Herring).

   - Remove unnecessary unlikely() from the cpufreq core (Igor Stoppa).

   - Add support for the r8a7744 SoC to the cpufreq-dt driver (Biju
     Das).

   - Update the dt-platdev cpufreq driver to allow RK3399 to have
     separate tunables per cluster (Dmitry Torokhov).

   - Fix the dma_alloc_coherent() usage in the tegra186 cpufreq driver
     (Christoph Hellwig).

   - Make the imx6q cpufreq driver read OCOTP through nvmem for
     imx6ul/imx6ull (Anson Huang).

   - Fix several bugs in the operating performance points (OPP)
     framework and make it more stable (Viresh Kumar, Dave Gerlach).

   - Update the devfreq subsystem to take changes in the APIs used by
     into account, fix some issues with it and make it stop print
     device_node.name directly (Bjorn Andersson, Enric Balletbo i Serra,
     Matthias Kaehlcke, Rob Herring, Vincent Donnefort, zhong jiang).

   - Prepare the generic power domains (genpd) framework for dealing
     with domains containing CPUs (Ulf Hansson).

   - Prevent sysfs attributes representing low-power S0 residency
     counters from being exposed if low-power S0 support is not
     indicated in ACPI FADT (Rajneesh Bhardwaj).

   - Get rid of custom CPU features macros for Intel CPUs from the
     intel_idle and RAPL drivers (Andy Shevchenko).

   - Update the tasks freezer to list tasks that refused to freeze and
     caused a system transition to a sleep state to be aborted (Todd
     Brandt).

   - Update the pm-graph set of tools to v5.2 (Todd Brandt).

   - Fix some issues in the cpupower utility (Anders Roxell, Prarit
     Bhargava)"

Erik Schmauss 08930d56c7 ACPICA: Remove acpi_gbl_group_module_level_code and only use acpi_gbl_execute_tables_as_methods instead
acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were
used to enable different table load behavior. The different table
load behaviors are as follows:

A.) acpi_gbl_group_module_level_code enabled the legacy approach where
    ASL if statements are executed after the namespace object has
    been loaded.
B.) acpi_gbl_execute_tables_as_methods is currently used to enable the
    table load to be a method invocation. This meaning that ASL If
    statements are executed in-line rather than deferred until after
    the ACPI namespace has been populated. This is the correct
    behavior and option A will be removed in the future.

We do not support a table load behavior where these variables are
assigned the same value. In otherwords, we only support option A or B
and do not need acpi_gbl_group_module_level_code to enable A. From now on,
acpi_gbl_execute_tables_as_methods == 0 enables option A and
acpi_gbl_execute_tables_as_methods == 1 enables option B.

Note: option A is expected to be removed in the future and option B
will become the only supported table load behavior.

Mika Westerberg 5f5e4890d5 ACPI / property: Allow multiple property compatible _DSD entries
It is possible to have _DSD entries where the data is compatible with
device properties format but are using different GUID for various reasons.
In addition to that there can be many such _DSD entries for a single device
such as for PCIe root port used to host a Thunderbolt hierarchy:

    Scope (\_SB.PCI0.RP21)
    {
        Name (_DSD, Package () {
            ToUUID ("6211e2c0-58a3-4af3-90e1-927a4e0c55a4"),
            Package () {
                Package () {"HotPlugSupportInD3", 1}
            },

            ToUUID ("efcc06cc-73ac-4bc3-bff0-76143807c389"),
            Package () {
                Package () {"ExternalFacingPort", 1},
                Package () {"UID", 0 }
            }
        })
    }

More information about these new _DSD entries can be found in:

  https://docs.microsoft.com/en-us/windows-hardware/drivers/pci/dsd-for-pcie-root-ports

To make these available for drivers via unified device property APIs,
modify ACPI property core so that it supports multiple _DSD entries
organized in a linked list. We also store GUID of each _DSD entry in struct
acpi_device_properties in case there is need to differentiate between
entries. The supported GUIDs are then listed in prp_guids array.

Robin Murphy a53eaef6da ACPICA: IORT: Add PMCG node supprt
PMCG nodes were added by IORT revision C, with the unfortunate oversight
that it only defined a single base address, and thus was incapable of
properly describing PMCG implementations with PMCG_CFGR.RELOC_CTRS = 1,
where the counters are in a separate page from the control registers.

Revision D corrects this by clarifying the existing field as the page 0
base address and adding a second field to describe the page 1 address
when implemented. With the spec now fit for purpose, let's support it.

Robin Murphy d87be0438e ACPICA: IORT: Update for revision D
IORT revision D contains a few additions and fixes to
currently-supported tables:

- SMMUv3 proximity domain field is enlarged to 4 bytes for consistency
  with SRAT
- Root complex nodes gain an address size limit field equivalent to that
  of named components
- Named component nodes gain a way to describe PASID (substream_ID)
  support, encoded in their flags

Additionally, we fix a couple of outstanding points in passing:
- Add the stall support flag for named components defined in revision C
- Fix SMMUv3 HTTU override mask, which should always have been 2 bits

Borislav Petkov cc7f3f1326 ghes, EDAC: Fix ghes_edac registration
Tony reported seeing

  "Internal error: Can't find EDAC structure"

when injecting correctable errors due to the fact that ghes_edac would
still load even if the whitelist won't hit. Drop the pr_err() in
ghes_edac_report_mem_error() for now due to the hacky way how ghes_edac
depends on ghes.c.

While at it, make ghes_edac_register() return an error if it doesn't hit
in the whitelist as it is the only sensible thing to do in that
situation.

Furthermore, move the call to it to happen last in ghes_probe() so that
GHES initializing properly does not depend on ghes_edac init at all
as latter is only reporting errors and not required for GHES's proper
functioning.

John Garry d87fb0917a ACPI / scan: Rename acpi_is_serial_bus_slave() for more general use
Currently the ACPI scan has special handling for serial bus slaves, in that
it makes it the responsibility of the slave device's parent to enumerate
the device.

To support other types of slave devices which require the same special
handling but where the bus is not strictly a serial bus, such as devices on
the HiSilicon LPC controller bus, rename acpi_is_serial_bus_slave() to
acpi_device_enumeration_by_parent(), so that the name can fit the wider
purpose.

Also rename the associated device flag acpi_device_flags.serial_bus_slave
to .enumeration_by_parent.

Joao Martins 4d0f1ce695 xen/acpi: upload _PSD info for non Dom0 CPUs too
All uploaded PM data from non-dom0 CPUs takes the info from vCPU 0 and
changing only the acpi_id. For processors which P-state coordination type
is HW_ALL (0xFD) it is OK to upload bogus P-state dependency information
(_PSD), because Xen will ignore any cpufreq domains created for past CPUs.

Albeit for platforms which expose coordination types as SW_ANY or SW_ALL,
this will have some unintended side effects. Effectively, it will look at
the P-state domain existence and *if it already exists* it will skip the
acpi-cpufreq initialization and thus inherit the policy from the first CPU
in the cpufreq domain. This will finally lead to the original cpu not
changing target freq to P0 other than the first in the domain. Which will
make turbo boost not getting enabled (e.g. for 'performance' governor) for
all cpus.

This patch fixes that, by also evaluating _PSD when we enumerate all ACPI
processors and thus always uploading the correct info to Xen. We export
acpi_processor_get_psd() for that this purpose, but change signature
to not assume an existent of acpi_processor given that ACPI isn't creating
an acpi_processor for non-dom0 CPUs.

Hans de Goede e7c2c3c909 ACPICA: Remove calling of _STA from acpi_get_object_info()
As the documentatuon above its declaration indicates, acpi_get_object_info()
is intended for early probe usage and as such should not call any methods
which may rely on op_regions, before this commit it was also calling _STA,
which on some systems does rely on op_regions.

Calling _STA before things are ready leads to errors such as these
(under Linux, on some hardware):

[    0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c)
               [generic_serial_bus] (20170831/evregion-166)

               \_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550)

End 2015 support for the _SUB method was removed for exactly the same
reason. Removing current_status from struct acpi_device_info only has a limited
impact. Within ACPICA it is only used by 2 debug messages, both
of which are modified to no longer print it with this commit.

Outside of ACPICA, there was one user in Linux, which has been patched to
no longer use current_status in Torvald's current master.

I've not checked if free_BSD or others are using the current_status field.

For the kernel-resident ACPICA, optionally be silent about the
NOT_FOUND case. Although this is potentially a serious problem,
it can generate a lot of noise/errors on platforms whose
firmware carries around a bunch of unused Package objects.
To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS
in the OS-specific header.

Schmauss, Erik 5a8361f7ec ACPICA: Integrate package handling with module-level code
ACPICA commit 8faf6fca445eb7219963d80543fb802302a7a8c7

This change completes the integration of the recent changes to
package object handling with the module-level code support.

For acpi_exec, the -ep flag is removed.

This change allows table load to behave as if it were a method
invocation. Before this, the definition block definition below would
have loaded all named objects at the root scope. After loading, it
would execute the if statements at the root scope.

DefinitionBlock (...)
{
  Name(OBJ1, 0)

  if (1)
  {
    Device (DEV1)
    {
      Name (_HID,0x0)
    }
  }
  Scope (DEV1)
  {
    Name (OBJ2)
  }
}

The above code would load OBJ1 to the namespace, defer the execution
of the if statement and attempt to add OBJ2 within the scope of DEV1.
Since DEV1 is not in scope, this would incur an AE_NOT_FOUND error.
After this error is emitted, the if block is invoked and DEV1 and its
_HID is added to the namespace.

This commit changes the behavior to execute the if block in place
rather than deferring it until all tables are loaded. The new
behavior is as follows: insert OBJ1 in the namespace, invoke the if
statement and add DEV1 and its _HID to the namespace, add OBJ2 to the
scope of DEV1.

Ognjen Galic fa93854f7a battery: Add the battery hooking API
This is a patch that implements a generic hooking API for the
generic ACPI battery driver.

With this new generic API, drivers can expose platform specific
behaviour via sysfs attributes in /sys/class/power_supply/BATn/
in a generic way.

A perfect example of the need for this API are Lenovo ThinkPads.

Lenovo ThinkPads have a ACPI extension that allows the setting of
start and stop charge thresholds in the EC and battery firmware
via ACPI. The thinkpad_acpi module can use this API to expose
sysfs attributes that it controls inside the ACPI battery driver
sysfs tree, under /sys/class/power_supply/BATN/.

The file drivers/acpi/battery.h has been moved to
include/acpi/battery.h and the includes inside ac.c, sbs.c, and
battery.c have been adjusted to reflect that.

When drivers hooks into the API, the API calls add_battery() for
each battery in the system that passes it a acpi_battery
struct. Then, the drivers can use device_create_file() to create
new sysfs attributes with that struct and identify the batteries
for per-battery attributes.

Andy Shevchenko 67dcf8a3e0 ACPI: utils: Introduce acpi_dev_get_first_match_name()
Sometimes the user wants to have device name of the match rather than
just checking if device present or not. To make life easier for such
users introduce acpi_dev_get_first_match_name() helper based on code
for acpi_dev_present().

For example, GPIO driver for Intel Merrifield needs to know the device
name of pin control to be able to apply GPIO mapping table to the proper
device.

To be more consistent with the purpose rename

  struct acpi_dev_present_info  -> struct acpi_dev_match_info
  acpi_dev_present_cb()         -> acpi_dev_match_cb()

in the utils.c file.

 2.) if the optional field is not present
 3.) the optional field is the last line of the data table

A change was made to dt_compile_table to return an AE_EOF under
these conditions.  This AE_EOF means that we are at the end of the
file.  The caller to dt_compile_table() is responsible for handling
this case. For DBG2 table, we will complete the compilation of this
subtable.  For other tables, this could be different.

Lv Zheng 164a08cee1 ACPICA: Dispatcher: Introduce timeout mechanism for infinite loop detection
ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9

This patch implements a new infinite loop detection mechanism to replace
the old one, it uses acpi_os_get_timer() to limit loop execution into a
determined time slice.
This is useful in case some hardware/firmware operations really require the
AML interpreter to wait while the old mechanism could expire too fast on
recent machines.

The new mechanism converts old acpi_gbl_max_loop_iterations to store the user
configurable value for the new mechanism in order to allow users to be
still able to configure this value for acpiexec via command line. This
patch also removes wrong initilization code of acpi_gbl_max_loop_iterations
accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the
default value is also properly tuned for acpiexec). Reported by M. Foronda,
fixed by Lv Zheng.

Lv Zheng a64a62ce9a ACPI / EC: Fix regression related to PM ops support in ECDT device
On platforms (ASUS X550ZE and possibly all ASUS X series) with valid ECDT
EC but invalid DSDT EC, EC PM ops won't be invoked as ECDT EC is not an
ACPI device. Thus the following commit actually removed post-resume
acpi_ec_enable_event() invocation for such platforms, and triggered a
regression on them that after being resumed, EC (actually should be ECDT)
driver stops handling EC events:

 Commit: c2b46d679b
 Subject: ACPI / EC: Add PM operations to improve event handling for resume process

Notice that the root cause actually is "ECDT is not an ACPI device" rather
than "the timing of acpi_ec_enable_event() invocation", this patch fixes
this issue by enumerating ECDT EC as an ACPI device. Due to the existence
of the noirq stage, the ability of tuning the timing of
acpi_ec_enable_event() invocation is still meaningful.

This patch is a little bit different from the posted fix by moving
acpi_config_boot_ec() from acpi_ec_ecdt_start() to acpi_ec_add() to make
sure that EC event handling won't be stopped as long as the ACPI EC driver
is bound. Thus the following sequence shouldn't disable EC event handling:
unbind,suspend,resume,bind.

Fixes: c2b46d679b (ACPI / EC: Add PM operations to improve event handling for resume process)

Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

Frédéric Danis e361d1f858 ACPI / scan: Fix enumeration for special UART devices
UART devices is expected to be enumerated by SerDev subsystem.

During ACPI scan, serial devices behind SPI, I2C or UART buses are not
enumerated, allowing them to be enumerated by their respective parents.

Rename *spi_i2c_slave* to *serial_bus_slave* as this will be used for serial
devices on serial buses (SPI, I2C or UART).

On Macs an empty ResourceTemplate is returned for uart slaves.
Instead the device properties "baud", "parity", "dataBits", "stopBits" are
provided. Add a check for "baud" in acpi_is_serial_bus_slave().

Srinivas Pandruvada eeb2d80d50 ACPI / LPIT: Add Low Power Idle Table (LPIT) support
Add functionality to read LPIT table, which provides:

 - Sysfs interface to read residency counters via
   /sys/devices/system/cpu/cpuidle/low_power_idle_cpu_residency_us
   /sys/devices/system/cpu/cpuidle/low_power_idle_system_residency_us

Here the count "low_power_idle_cpu_residency_us" shows the time spent
by CPU package in low power state.  This is read via MSR interface,
which points to MSR for PKG C10.

Here the count "low_power_idle_system_residency_us" show the count the
system was in low power state. This is read via MMIO interface. This
is mapped to SLP_S0 residency on modern Intel systems. This residency
is achieved only when CPU is in PKG C10 and all functional blocks are
in low power state.

It is possible that none of the above counters present or anyone of the
counter present or all counters present.

For example: On my Kabylake system both of the above counters present.
After suspend to idle these counts updated and prints:

 6916179
 6998564

This counter can be read by tools like turbostat to display. Or it can
be used to debug, if modern systems are reaching desired low power state.

 - Provides an interface to read residency counter memory address

   This address can be used to get the base address of PMC memory
   mapped IO.  This is utilized by intel_pmc_core driver to print
   more debug information.

In addition, to avoid code duplication to read iomem, removed the read of
iomem from acpi_os_read_memory() in osl.c and made a common function
acpi_os_read_iomem(). This new function is used for reading iomem in
in both osl.c and acpi_lpit.c.

John Hubbard 9e987b70ad ACPI / bus: Make ACPI_HANDLE() work for non-GPL code again
Due to commit db3e50f323 (device property: Get rid of struct
fwnode_handle type field), ACPI_HANDLE() inadvertently became
a GPL-only call. The call path that led to that was:

ACPI_HANDLE()
    ACPI_COMPANION()
        to_acpi_device_node()
            is_acpi_device_node()
                acpi_device_fwnode_ops
                    DECLARE_ACPI_FWNODE_OPS(acpi_device_fwnode_ops);

...and the new DECLARE_ACPI_FWNODE_OPS() includes
EXPORT_SYMBOL_GPL, whereas previously it was a static struct.

In order to avoid changing any of that, let's instead provide ever
so slightly better encapsulation of those struct fwnode_operations
instances. Those do not really need to be directly used in
inline function calls in header files. Simply moving two small
functions (is_acpi_device_node and is_acpi_data_node) out of
acpi_bus.h, and into a .c file, does that.

That leaves the internals of struct fwnode_operations as GPL-only
(which I think was the intent all along), but un-breaks any driver
code out there that relies on the ACPI subsystem's being (historically)
an EXPORT_SYMBOL-usable system. By that, I mean, ACPI_HANDLE() and
other basic ACPI calls were non-GPL-protected.

Also, while I'm there, remove a tiny bit of redundancy that was missed
in the earlier commit, by having is_acpi_node() use the other two
routines, instead of checking fwnode directly.

Rafael J. Wysocki 1312b7e0ca ACPICA: Make it possible to enable runtime GPEs earlier
Runtime GPEs have corresponding _Lxx/_Exx methods and are enabled
automatically during the initialization of the ACPI subsystem through
acpi_update_all_gpes() with the assumption that acpi_setup_gpe_for_wake()
will be called in advance for all of the GPEs pointed to by _PRW
objects in the namespace that may be affected by acpi_update_all_gpes().
That is, acpi_ev_initialize_gpe_block() can only be called for a GPE
block after acpi_setup_gpe_for_wake() has been called for all of the
_PRW (wakeup) GPEs in it.

The platform firmware on some systems, however, expects GPEs to be
enabled before the enumeration of devices which is when
acpi_setup_gpe_for_wake() is called and that goes against the above
assumption.

For this reason, introduce a new flag to be set by
acpi_ev_initialize_gpe_block() when automatically enabling a GPE
to indicate to acpi_setup_gpe_for_wake() that it needs to drop the
reference to the GPE coming from acpi_ev_initialize_gpe_block()
and modify acpi_setup_gpe_for_wake() accordingly.  These changes
allow acpi_setup_gpe_for_wake() and acpi_ev_initialize_gpe_block()
to be invoked in any order.

Lorenzo Pieralisi c04ac679c6 ACPI: Introduce DMA ranges parsing
Some devices have limited addressing capabilities and cannot
reference the whole memory address space while carrying out DMA
operations (eg some devices with bus address bits range smaller than
system bus - which prevents them from using bus addresses that are
otherwise valid for the system).

The ACPI _DMA object allows bus devices to define the DMA window that is
actually addressable by devices that sit upstream the bus, therefore
providing a means to parse and initialize the devices DMA masks and
addressable DMA range size.

By relying on the generic ACPI kernel layer to retrieve and parse
resources, introduce ACPI core code to parse the _DMA object.

Lv Zheng 65082bfcb4 ACPICA: CLib: Add short multiply/shift support
ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5

In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit
multiply/shift supports are also required to be implemented. Otherwise,
MSVC complains:
 acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul
 acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr

Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
   different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.

This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng.

For Linux kernel, this patch is a functional no-op.

ACPICA commit 43ff22215f0fcd8ca80abec5712a07d2cc9a801d

acpi.h inclusion order need to be changed to build EDK-II ports of
acpidump on Windows as va_list is used before it's definition in that
environment. As we only need to ensure order of acenv.h/acenvex.h to
be pre/post ACPICA type definitions, inclusion order is changed to make
MSVC builds happy. Lv Zheng.

Lv Zheng 4eebedd8f1 ACPICA: Divergences: reduce access size definitions
ACPICA commit cf27b3c98883d2a15d932016792fcb8272ace96d

The following commit introduces definition of access width to ACPICA.
  Commit: 2bece49394
  Subject: ACPI: SPCR: Use access width to determine mmio usage

Actually the access bit width can be calculated via access width. It
would be better to define a macro calculating bit width rather than
defining fixed values. This patch thus cleans up the definitions to
reduce divergences.

Rafael J. Wysocki 1ba51a7c14 ACPI / PCI / PM: Rework acpi_pci_propagate_wakeup()
The acpi_pci_propagate_wakeup() routine is there to handle cases in
which PCI bridges (or PCIe ports) are expected to signal wakeup
for devices below them, but currently it doesn't do that correctly.

The problem is that acpi_pci_propagate_wakeup() uses
acpi_pm_set_device_wakeup() for bridges and if that routine is
called for multiple times to disable wakeup for the same device,
it will disable it on the first invocation and the next calls
will have no effect (it works analogously when called to enable
wakeup, but that is not a problem).

Now, say acpi_pci_propagate_wakeup() has been called for two
different devices under the same bridge and it has called
acpi_pm_set_device_wakeup() for that bridge each time.  The
bridge is now enabled to generate wakeup signals.  Next,
suppose that one of the devices below it resumes and
acpi_pci_propagate_wakeup() is called to disable wakeup for that
device.  It will then call acpi_pm_set_device_wakeup() for the bridge
and that will effectively disable remote wakeup for all devices under
it even though some of them may still be suspended and remote wakeup
may be expected to work for them.

To address this (arguably theoretical) issue, allow
wakeup.enable_count under struct acpi_device to grow beyond 1 in
certain situations.  In particular, allow that to happen in
acpi_pci_propagate_wakeup() when wakeup is enabled or disabled
for PCI bridges, so that wakeup is actually disabled for the
bridge when all devices under it resume and not when just one
of them does that.

Rafael J. Wysocki 99d8845e75 ACPI / PM: Split acpi_device_wakeup()
To prepare for a subsequent change and make the code somewhat easier
to follow, do the following in the ACPI device wakeup handling code:

 * Replace wakeup.flags.enabled under struct acpi_device with
   wakeup.enable_count as that will be necessary going forward.

   For now, wakeup.enable_count is not allowed to grow beyond 1,
   so the current behavior is retained.

 * Split acpi_device_wakeup() into acpi_device_wakeup_enable()
   and acpi_device_wakeup_disable() and modify the callers of
   it accordingly.

 * Introduce a new acpi_wakeup_lock mutex to protect the wakeup
   enabling/disabling code from races in case it is executed
   more than once in parallel for the same device (which may
   happen for bridges theoretically).

Sakari Ailus db3e50f323 device property: Get rid of struct fwnode_handle type field
Instead of relying on the struct fwnode_handle type field, define
fwnode_operations structs for all separate types of fwnodes. To find out
the type, compare to the ops field to relevant ops structs.

This change has two benefits:

1. it avoids adding the type field to each and every instance of struct
fwnode_handle, thus saving memory and

2. makes the ops field the single factor that defines both the types of
the fwnode as well as defines the implementation of its operations,
decreasing the possibility of bugs when developing code dealing with
fwnode internals.

Pull ACPI updates from Rafael Wysocki:
 "These mostly update the ACPICA code in the kernel to upstream revision
  20170531 which covers all of the new material from ACPI 6.2, including
  new tables (WSMT, HMAT, PPTT), new subtables and definition changes
  for some existing tables (BGRT, HEST, SRAT, TPM2, PCCT), new resource
  descriptor macros for pin control, support for new predefined methods
  (_LSI, _LSR, _LSW, _HMA), fixes and cleanups.

  On top of that, an additional ACPICA change from Kees (which also is
  upstream already) switches all of the definitions of function pointer
  structures in ACPICA to use designated initializers so as to make the
  structure layout randomization GCC plugin work with it.

  The rest is a few fixes and cleanups in the EC driver, an xpower PMIC
  driver update, a new backlight blacklist entry, and update of the
  tables configfs interface and a messages formatting cleanup.

  Specifics:

   - Update the ACPICA code in the kernel to upstream revision revision
     20170531 (which covers all of the new material from ACPI 6.2)
     including:
      * Support for the PinFunction(), PinConfig(), PinGroup(),
        PinGroupFunction(), and PinGroupConfig() resource descriptors
        (Mika Westerberg).
      * Support for new subtables in HEST and SRAT, new notify value for
        HEST, header support for TPM2 table changes, and BGRT Status
        field update (Bob Moore).
      * Support for new PCCT subtables (David Box).
      * Support for _LSI, _LSR, _LSW, and _HMA as predefined methods
        (Erik Schmauss).
      * Support for the new WSMT, HMAT, and PPTT tables (Lv Zheng).
      * New UUID values for Processor Properties (Bob Moore).
      * New notify values for memory attributes and graceful shutdown
        (Bob Moore).
      * Fix related to the PCAT_COMPAT MADT flag (Janosch Hildebrand).
      * Resource to AML conversion fix for resources containing GPIOs
        (Mika Westerberg).
      * Disassembler-related updates (Bob Moore, David Box, Erik
        Schmauss).
      * Assorted fixes and cleanups (Bob Moore, Erik Schmauss, Lv Zheng,
        Cao Jin).

   - Modify ACPICA to always use designated initializers for function
     pointer structures to make the structure layout randomization GCC
     plugin work with it (Kees Cook).

   - Update the tables configfs interface to unload SSDTs on configfs
     entry removal (Jan Kiszka).

   - Add support for the GPI1 regulator to the xpower PMIC Operation
     Region handler (Hans de Goede).

   - Fix ACPI EC issues related to conflicting EC definitions in the
     ECDT and in the ACPI namespace (Lv Zheng, Carlo Caione, Chris
     Chiu).

   - Fix an interrupt storm issue in the EC driver and make its debug
     output work with dynamic debug as expected (Lv Zheng).

   - Add ACPI backlight quirk for Dell Precision 7510 (Shih-Yuan Lee).

   - Fix whitespace in pr_fmt() to align log entries properly in some
     places in the ACPI subsystem (Vincent Legoll)"

Loc Ho 2bece49394 ACPI: SPCR: Use access width to determine mmio usage
The current SPCR code does not check the access width of the MMIO, and
uses a default of 8bit register accesses.  This prevents devices that
only do 16 or 32bit register accesses from working.  By simply checking
this field and setting the MMIO string appropriately, this issue can be
corrected.  To prevent any legacy issues, the code will default to 8bit
accesses if the value is anything but 16 or 32.

Rafael J. Wysocki 8370c2dc4c PCI / PM: Drop pme_interrupt flag from struct pci_dev
The pme_interrupt flag in struct pci_dev is set when PMEs generated
by the device are going to be signaled via root port PME interrupts.

Ironically enough, that information is only used by the code setting
up device wakeup through ACPI which returns as soon as it sees the
pme_interrupt flag set while setting up "remote runtime wakeup".
That is questionable, however, because in theory there may be PCIe
devices using out-of-band PME signaling under root ports handled
by the native PME code or devices requiring wakeup power setup to be
carried out by AML.  For such devices, ACPI wakeup should be invoked
regardless of whether or not native PME signaling is used in general.

For this reason, drop the pme_interrupt flag and rework the code
using it which then allows the ACPI-based device wakeup handling
in PCI to be consolidated to use one code path for both "runtime
remote wakeup" and system wakeup (from sleep states).

Rafael J. Wysocki 4d183d0419 ACPI / PM: Consolidate device wakeup settings code
Currently, there are two separate ways of handling device wakeup
settings in the ACPI core, depending on whether this is runtime
wakeup or system wakeup (from sleep states).  However, after the
previous commit eliminating the run_wake ACPI device wakeup flag,
there is no difference between the two any more at the ACPI level,
so they can be combined.

For this reason, introduce acpi_pm_set_device_wakeup() to replace both
acpi_pm_device_run_wake() and acpi_pm_device_sleep_wake() and make it
check the ACPI device object's wakeup.valid flag to determine whether
or not the device can be set up to generate wakeup signals.

Also notice that zpodd_enable/disable_run_wake() only call
device_set_run_wake() because acpi_pm_device_run_wake() called
device_run_wake(), which is not done by acpi_pm_set_device_wakeup(),
so drop the now redundant device_set_run_wake() calls from there.

Rafael J. Wysocki a1a66393e3 ACPI / PM: Drop run_wake from struct acpi_device_wakeup_flags
The run_wake flag in struct acpi_device_wakeup_flags stores the
information on whether or not the device can generate wakeup
signals at run time, but in ACPI that really is equivalent to
being able to generate wakeup signals at all.

In fact, run_wake will always be set after successful executeion of
acpi_setup_gpe_for_wake(), but if that fails, the device will not be
able to use a wakeup GPE at all, so it won't be able to wake up the
systems from sleep states too.  Hence, run_wake actually means that
the device is capable of triggering wakeup and so it is equivalent
to the valid flag.

For this reason, drop run_wake from struct acpi_device_wakeup_flags
and make sure that the valid flag is only set if
acpi_setup_gpe_for_wake() has been successful.

The struct layout randomization plugin detects and randomizes any structs
that contain only function pointers. Once layout is randomized, all
initialization must be designated or the compiler will misalign the
assignments. This switches all the ACPICA function pointer struct to
use designated initializers, using the proposed upstream ACPICA macro:

Tyler Baicar 621f48e40e arm/arm64: KVM: add guest SEA support
Currently external aborts are unsupported by the guest abort
handling. Add handling for SEAs so that the host kernel reports
SEAs which occur in the guest kernel.

When an SEA occurs in the guest kernel, the guest exits and is
routed to kvm_handle_guest_abort(). Prior to this patch, a print
message of an unsupported FSC would be printed and nothing else
would happen. With this patch, the code gets routed to the APEI
handling of SEAs in the host kernel to report the SEA information.

Tyler Baicar 7edda0886b acpi: apei: handle SEA notification type for ARMv8
ARM APEI extension proposal added SEA (Synchronous External Abort)
notification type for ARMv8.
Add a new GHES error source handling function for SEA. If an error
source's notification type is SEA, then this function can be registered
into the SEA exception handler. That way GHES will parse and report
SEA exceptions when they occur.
An SEA can interrupt code that had interrupts masked and is treated as
an NMI. To aid this the page of address space for mapping APEI buffers
while in_nmi() is always reserved, and ghes_ioremap_pfn_nmi() is
changed to use the helper methods to find the prot_t to map with in
the same way as ghes_ioremap_pfn_irq().

Tyler Baicar 42aa560446 acpi: apei: read ack upon ghes record consumption
A RAS (Reliability, Availability, Serviceability) controller
may be a separate processor running in parallel with OS
execution, and may generate error records for consumption by
the OS. If the RAS controller produces multiple error records,
then they may be overwritten before the OS has consumed them.

The Generic Hardware Error Source (GHES) v2 structure
introduces the capability for the OS to acknowledge the
consumption of the error record generated by the RAS
controller. A RAS controller supporting GHESv2 shall wait for
the acknowledgment before writing a new error record, thus
eliminating the race condition.

Add support for parsing of GHESv2 sub-tables as well.
