Geert Uytterhoeven b6e56e4c1f arm64: dts: r8a7795: Link ARM GIC to clock and clock domain
Link the ARM GIC to the INTC-AP module clock, and add it to the SYSC
"always-on" PM Domain, so it can be power managed using that clock.

Note that currently the GIC-400 driver doesn't support module clocks nor
Runtime PM, so this must be handled as a critical clock.

Robin Murphy adbe7e26f4 arm64: dma-mapping: Fix dma_mapping_error() when bypassing SWIOTLB
When bypassing SWIOTLB on small-memory systems, we need to avoid calling
into swiotlb_dma_mapping_error() in exactly the same way as we avoid
swiotlb_dma_supported(), because the former also relies on SWIOTLB state
being initialised.

Under the assumptions for which we skip SWIOTLB, dma_map_{single,page}()
will only ever return the DMA-offset-adjusted physical address of the
page passed in, thus we can report success unconditionally.

Fixes: b67a8b29df ("arm64: mm: only initialize swiotlb when necessary")

Ard Biesheuvel 79ba11d24b arm64: kernel: do not mark reserved memory regions as IORESOURCE_BUSY
Memory regions marked as NOMAP should not be used for general allocation
by the kernel, and should not even be covered by the linear mapping
(hence the name). However, drivers or other subsystems (such as ACPI)
that access the firmware directly may legally access them, which means
it is also reasonable for such drivers to claim them by invoking
request_resource(). Currently, this is prevented by the fact that arm64's
request_standard_resources() marks reserved regions as IORESOURCE_BUSY.

So drop the IORESOURCE_BUSY flag from these requests.

Add a file to debugfs to read the in-kernel state of the vgic.  We don't
do any locking of the entire VGIC state while traversing all the IRQs,

but should take care to pause the VM using facilities in user space for
that purpose.

We also don't support LPIs yet, but they can be added easily if needed.

Will Deacon 4a8d8a14c0 arm64: dma-mapping: Only swizzle DMA ops for IOMMU_DOMAIN_DMA
The arm64 DMA-mapping implementation sets the DMA ops to the IOMMU DMA
ops if we detect that an IOMMU is present for the master and the DMA
ranges are valid.

In the case when the IOMMU domain for the device is not of type
IOMMU_DOMAIN_DMA, then we have no business swizzling the ops, since
we're not in control of the underlying address space. This patch leaves
the DMA ops alone for masters attached to non-DMA IOMMU domains.

Mark Rutland 7d9e8f71b9 arm64: avoid returning from bad_mode
Generally, taking an unexpected exception should be a fatal event, and
bad_mode is intended to cater for this. However, it should be possible
to contain unexpected synchronous exceptions from EL0 without bringing
the kernel down, by sending a SIGILL to the task.

We tried to apply this approach in commit 9955ac47f4 ("arm64:
don't kill the kernel on a bad esr from el0"), by sending a signal for
any bad_mode call resulting from an EL0 exception.

However, this also applies to other unexpected exceptions, such as
SError and FIQ. The entry paths for these exceptions branch to bad_mode
without configuring the link register, and have no kernel_exit. Thus, if
we take one of these exceptions from EL0, bad_mode will eventually
return to the original user link register value.

This patch fixes this by introducing a new bad_el0_sync handler to cater
for the recoverable case, and restoring bad_mode to its original state,
whereby it calls panic() and never returns. The recoverable case
branches to bad_el0_sync with a bl, and returns to userspace via the
usual ret_to_user mechanism.

The first batch of Juno boards included a discrete USB controller chip
as a contingency in case of issues with the USB 2.0 IP integrated into
the SoC. As it turned out, the latter was fine, and to the best of my
knowledge the motherboard USB was never even brought up and validated.

Since this also isn't present on later boards, and uses a compatible
string undocumented and unmatched by any driver in the kernel, let's
just tidy it away for ever to avoid any confusion.

sneaky one which goes away as soon as you connect an external debugger
to have a look at where it's stuck (thus powering up DEBUGSYS by other
means and allowing it to make progress again before actually halting...)

Sudeep Holla 19ac17c031 arm64: dts: juno: refactor CoreSight support on Juno r0
Currently the Coresight components are supported only on Juno r0
variant. In preparation to add support to Juno r1/r2 variants, this
patch refactors the existing coresight device nodes so that r1/r2
support can be added easily.

It also cleans up some of the device node names which were previously
named so as they were confused as the labels rather than the node names.

Sudeep Holla d29e849caf arm64: dts: juno: remove dtsi nesting inside tree structure
Currently juno-clock.dtsi and juno-base.dtsi are nested badly inside
the device tree structure. It's generally good practice to ensure that
individual dtsi stand by themselves at the top of the file.

This patch removes the nesting of the above mentioned dtsi files and
makes them independent.

Neil Armstrong f7bcd4b6f6 ARM64: dts: meson-gxbb-odroidc2: Disable SCPI DVFS
The current hardware is not able to run with all cores enabled at a
cluster frequency superior at 1536MHz.
But the currently shipped u-boot for the platform still reports an OPP
table with possible DVFS frequency up to 2GHz, and will not change since
the off-tree linux tree supports limiting the OPPs with a kernel parameter.
A recent u-boot change reports the boot-time DVFS around 100MHz and
the default performance cpufreq governor sets the maximum frequency.
Previous version of u-boot reported to be already at the max OPP and
left the OPP as is.
Nevertheless, other governors like ondemand could setup the max frequency
and make the system crash.

This patch disables the DVFS clock and disables cpufreq.

Mark Rutland 829d2bd133 arm64: entry-ftrace.S: avoid open-coded {adr,ldr}_l
Some places in the kernel open-code sequences using ADRP for a symbol
another instruction using a :lo12: relocation for that same symbol.
These sequences are easy to get wrong, and more painful to read than is
necessary. For these reasons, it is preferable to use the
{adr,ldr,str}_l macros for these cases.

This patch makes use of these in entry-ftrace.S, removing open-coded
sequences using adrp. This results in a minor code change, since a
temporary register is not used when generating the address for some
symbols, but this is fine, as the value of the temporary register is not
used elsewhere.

Sudeep Holla 9a802431c5 arm64: cacheinfo: add support to override cache levels via device tree
The cache hierarchy can be identified through Cache Level ID(CLIDR)
architected system register. However in some cases it will provide
only the number of cache levels that are integrated into the processor
itself. In other words, it can't provide any information about the
caches that are external and/or transparent.

Some platforms require to export the information about all such external
caches to the userspace applications via the sysfs interface.

This patch adds support to override the cache levels using device tree
to take such external non-architected caches into account.

Alexander Graf 524dabe1c6 arm64: Fix swiotlb fallback allocation
Commit b67a8b29df introduced logic to skip swiotlb allocation when all memory
is DMA accessible anyway.

While this is a great idea, __dma_alloc still calls swiotlb code unconditionally
to allocate memory when there is no CMA memory available. The swiotlb code is
called to ensure that we at least try get_free_pages().

Without initialization, swiotlb allocation code tries to access io_tlb_list
which is NULL. That results in a stack trace like this:

  Unable to handle kernel NULL pointer dereference at virtual address 00000000
  [...]
  [<ffff00000845b908>] swiotlb_tbl_map_single+0xd0/0x2b0

  [<ffff000000b46a94>] vc4_drm_bind+0xec/0x168 [vc4]
  [...]

Thankfully swiotlb code just learned how to not do allocations with the FORCE_NO
option. This patch configures the swiotlb code to use that if we decide not to
initialize the swiotlb framework.

The rpmcc driver is providing the XO clock, which is the parent of almost
all clocks. But during boot, this driver may probe later and leave most of
the clocks without parent. The common clock framework currently reports
invalid rate for orphan clocks and this may confuse drivers.

To resolve this, use fixed clocks registration until we have some support
to deal with the this issue. Removing the generic rpmcc compatible is
enough to switch back to fixed factor XO clock.

their relative power efficiency. Higher weights express higher power
efficiency.  Weighting is relative such that if each cooling device has a

heterogeneous systems where two cooling devices may perform the same kind
of compute, but with different efficiency.

timer.  Bit positions of CNTHCTL_EL2 are changing depending on
HCR_EL2.E2H bit.  EL1PCEN and EL1PCTEN are 1st and 0th bits when E2H is
not set, but they are 11th and 10th bits respectively when E2H is set.

In fact, on VHE we only need to set those bits once, not for every world
switch. This is because the host kernel runs in EL2 with HCR_EL2.TGE ==
1, which makes those bits have no effect for the host kernel execution.
So we just set those bits once for guests, and that's it.

When CONFIG_RANDOMIZE_MODULE_REGION_FULL=y, the offset between loaded
modules and the core kernel may exceed 4 GB, putting symbols exported
by the core kernel out of the reach of the ordinary adrp/add instruction
pairs used to generate relative symbol references. So make the adr_l

Ard Biesheuvel 1abee99eaf crypto: arm64/aes - reimplement bit-sliced ARM/NEON implementation for arm64
This is a reimplementation of the NEON version of the bit-sliced AES
algorithm. This code is heavily based on Andy Polyakov's OpenSSL version
for ARM, which is also available in the kernel. This is an alternative for
the existing NEON implementation for arm64 authored by me, which suffers
from poor performance due to its reliance on the pathologically slow four
register variant of the tbl/tbx NEON instruction.

This version is about ~30% (*) faster than the generic C code, but only in
cases where the input can be 8x interleaved (this is a fundamental property
of bit slicing). For this reason, only the chaining modes ECB, XTS and CTR
are implemented. (The significance of ECB is that it could potentially be
used by other chaining modes)

* Measured on Cortex-A57. Note that this is still an order of magnitude
  slower than the implementations that use the dedicated AES instructions
  introduced in ARMv8, but those are part of an optional extension, and so
  it is good to have a fallback.

Ard Biesheuvel bed593c0e8 crypto: arm64/aes - add scalar implementation
This adds a scalar implementation of AES, based on the precomputed tables
that are exposed by the generic AES code. Since rotates are cheap on arm64,
this implementation only uses the 4 core tables (of 1 KB each), and avoids
the prerotated ones, reducing the D-cache footprint by 75%.

On Cortex-A57, this code manages 13.0 cycles per byte, which is ~34% faster
than the generic C code. (Note that this is still >13x slower than the code
that uses the optional ARMv8 Crypto Extensions, which manages <1 cycles per
byte.)

In addition to wrapping the AES-CTR cipher into the async SIMD wrapper,
which exposes it as an async skcipher that defers processing to process
context, expose our AES-CTR implementation directly as a synchronous cipher
as well, but with a lower priority.

This makes the AES-CTR transform usable in places where synchronous
transforms are required, such as the MAC802.11 encryption code, which
executes in sotfirq context, where SIMD processing is allowed on arm64.
Users of the async transform will keep the existing behavior.

2) ID_AA64DFR1_EL1 is RAZ and should use the table for RAZ register.

3) ftr_generic32 is used to represent a register with a 32bit feature

   we don't have a 64bit singe feature register, kill ftr_generic.

Mark Rutland 564279ff6f arm64: cpufeature: remove explicit RAZ fields
We currently have some RAZ fields described explicitly in our
arm64_ftr_bits arrays. These are inconsistently commented, grouped,
and/or applied, and maintaining these is error-prone.

Luckily, we don't need these at all. We'll never need to inspect RAZ
fields to determine feature support, and init_cpu_ftr_reg() will ensure
that any bits without a corresponding arm64_ftr_bits entry are treated
as RES0 with strict matching requirements. In check_update_ftr_reg()
we'll then compare these bits from the relevant cpuinfo_arm64
structures, and need not store them in a arm64_ftr_reg.

This patch removes the unnecessary arm64_ftr_bits entries for RES0 bits.

Mark Rutland b389d7997a arm64: cpufeature: treat unknown fields as RES0
Any fields not defined in an arm64_ftr_bits entry are propagated to the
system-wide register value in init_cpu_ftr_reg(), and while we require
that these strictly match for the sanity checks, we don't update them in
update_cpu_ftr_reg().

Generally, the lack of an arm64_ftr_bits entry indicates that the bits
are currently RES0 (as is the case for the upper 32 bits of all
supposedly 32-bit registers).

A better default would be to use zero for the system-wide value of
unallocated bits, making all register checking consistent, and allowing
for subsequent simplifications to the arm64_ftr_bits arrays.

This patch updates init_cpu_ftr_reg() to treat unallocated bits as RES0
for the purpose of the system-wide safe value. These bits will still be
sanity checked with strict match requirements, as is currently the case.

James Morse c8b06e3fdd arm64: Remove useless UAO IPI and describe how this gets enabled
Since its introduction, the UAO enable call was broken, and useless.
commit 2a6dcb2b5f ("arm64: cpufeature: Schedule enable() calls instead
of calling them via IPI"), fixed the framework so that these calls
are scheduled, so that they can modify PSTATE.

Now it is just useless. Remove it. UAO is enabled by the code patching
which causes get_user() and friends to use the 'ldtr' family of
instructions. This relies on the PSTATE.UAO bit being set to match
addr_limit, which we do in uao_thread_switch() called via __switch_to().

All that is needed to enable UAO is patch the code, and call schedule().
__apply_alternatives_multi_stop() calls stop_machine() when it modifies
the kernel text to enable the alternatives, (including the UAO code in
uao_thread_switch()). Once stop_machine() has finished __switch_to() is
called to reschedule the original task, this causes PSTATE.UAO to be set
appropriately. An explicit enable() call is not needed.

If C - A > D - B, then we end up over compensating for the time spent in
__switch_to giving rise to negative times in the trace output.

On x86, __switch_to is not traced if function graph tracer is enabled.
Do the same for arm64 as well.

Mark Rutland 9d84fb27fa arm64: restore get_current() optimisation
Commit c02433dd6d ("arm64: split thread_info from task stack")
inverted the relationship between get_current() and
current_thread_info(), with sp_el0 now holding the current task_struct
rather than the current thead_info. The new implementation of
get_current() prevents the compiler from being able to optimize repeated
calls to either, resulting in a noticeable penalty in some
microbenchmarks.

This patch restores the previous optimisation by implementing
get_current() in the same way as our old current_thread_info(), using a
non-volatile asm statement.

Recent changes made KERN_CONT mandatory for continued lines. In the
absence of KERN_CONT, a newline may be implicit inserted by the core
printk code.

In show_pte, we (erroneously) use printk without KERN_CONT for continued
prints, resulting in output being split across a number of lines, and
not matching the intended output, e.g.

[ff000000000000] *pgd=00000009f511b003

The root cause is that usb2-phy suspended earlier than ehci/ohci
(usb2-phy will be auto suspended if no devices plug-in). and the
clk-480m provided by it was disabled if no module used. However,
some suspend process related ehci/ohci are base on this clock,
so we should refer it into ehci/ohci driver to prevent this case.

The u2phy clock flow like this:
===
      u2phy ________________
           |                |    |-----> UTMI_CLK ---------> | EHCI |
OSC_24M ---|---> PHY_PLL----|----|
           |________^_______|    |-----> 480M_CLK ---|G|---> | USBPHY_480M_SRC| ----> USBPHY_480M for SoC
                    |
                    |

Sudeep Holla 1dff32d7df arm64: dts: vexpress: Support GICC_DIR operations
The GICv2 CPU interface registers span across 8K, not 4K as indicated in
the DT.  Only the GICC_DIR register is located after the initial 4K
boundary, leaving a functional system but without support for separately
EOI'ing and deactivating interrupts.

After this change the system supports split priority drop and interrupt
deactivation. This patch is based on similar one from Christoffer Dall:

Lv Zheng 6b11d1d677 ACPI / osl: Remove acpi_get_table_with_size()/early_acpi_os_unmap_memory() users
This patch removes the users of the deprectated APIs:
 acpi_get_table_with_size()
 early_acpi_os_unmap_memory()
The following APIs should be used instead of:
 acpi_get_table()
 acpi_put_table()

The deprecated APIs are invented to be a replacement of acpi_get_table()
during the early stage so that the early mapped pointer will not be stored
in ACPICA core and thus the late stage acpi_get_table() won't return a
wrong pointer. The mapping size is returned just because it is required by
early_acpi_os_unmap_memory() to unmap the pointer during early stage.

But as the mapping size equals to the acpi_table_header.length
(see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when
such a convenient result is returned, driver code will start to use it
instead of accessing acpi_table_header to obtain the length.

Thus this patch cleans up the drivers by replacing returned table size with
acpi_table_header.length, and should be a no-op.

Linus Torvalds 482c3e8835 ARM: 64-bit DT updates for v4.10
A couple of interesting new SoC platforms are now supported, these are
 the respective DTS sources:
 
 - Samsung Exynos5433 mobile phone platform, including an (almost) fully
   supported phone reference board.
 - Hisilicon Hip07 server platform and D05 board, the latest iteration
   of their product line, now with 64 Cortex-A72 cores across two
   sockets.
 - Allwinner A64 SoC, the first 64-bit chip from their "sunxi" product
   line, used in Android tablets and ultra-cheap development boards
 - NXP LS1046A Communication processor, improving on the earlier LS1043A
   with faster CPU cores
 - Qualcomm MSM8992 (Snapdragon 808) and MSM8994 (Snapdragon 810)
   mobile phone SoCs
 - Early support for the Nvidia Tegra Tegra186 SoC
 - Amlogic S905D is a minor variant of their existing Android consumer
   product line
 - Rockchip PX5 automotive platform, a close relative of their popular
   rk3368 Android tablet chips
 
 Aside from the respective evaluation platforms for the above
 chips, there are only a few consumer devices and boards added
 this time:
 
 - Huawei Nexus 6P (Angler) mobile phone
 - LG Nexus 5x (Bullhead) mobile phone
 - Nexbox A1 and A95X Android TV boxes
 - Pine64 development board based on Allwinner A64
 - Globalscale Marvell ESPRESSOBin community board based on Armada 3700
 - Renesas "R-Car Starter Kit Pro" (M3ULCB) low-cost automotive  board
 
 For the existing platforms, we get bug fixes and new peripheral support
 for Juno, Renesas, Uniphier, Amlogic, Samsung, Broadcom, Rockchip, Berlin,
 and ZTE.
 
 Conflicts:
 - Documentation/devicetree/bindings/arm/shmobile.txt: a
   rename/add conflict, keep both modifications and maintain
   alphabetical ordering.
 - arch/arm64/boot/dts/*/*.dtsi: nodes were added in netdev,

Linus Torvalds 786a72d791 ARM: DT updates for v4.10
Lots of changes as usual, so I'm trying to be brief here. Most of the
 new hardware support has the respective driver changes merged through
 other trees or has had it available for a while, so this is where things
 come together.
 
 We get a DT descriptions for a couple of new SoCs, all of them variants
 of other chips we already support, and usually coming with a new
 evaluation board:
 
 - Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
 - Qualcomm MDM9615 LTE baseband
 - NXP imx6ull, the latest and smallest i.MX6 application processor variant
 - Renesas RZ/G (r8a7743 and r8a7745) application processors
 - Rockchip PX3, a variant of the rk3188 chip used in Android tablets
 - Rockchip rk1108 single-core application processor
 - ST stm32f746 Cortex-M7 based microcontroller
 - TI DRA71x automotive processors
 
 These are commercially available consumer platforms we now support:
 - Motorola Droid 4 (xt894) mobile phone
 - Rikomagic MK808 Android TV stick based on Rockchips rx3066
 - Cloud Engines PogoPlug v3 based on OX820
 - Various Broadcom based wireless devices:
   - Netgear R8500 router
   - Tenda AC9 router
   - TP-LINK Archer C9 V1
   - Luxul XAP-1510 Access point
 - Turris Omnia open hardware router based on Armada 385
 
 And a couple of new boards targeted at developers, makers
 or industrial integration:
 - Macnica Sodia development platform for Altera socfpga (Cyclone V)
 - MicroZed board based on Xilinx Zynq FPGA platforms
 - TOPEET itop/elite based on exynos4412
 - WP8548 MangOH Open Hardware platform for IOT, based on
   Qualcomm MDM9615
 - NextThing CHIP Pro gadget
 - NanoPi M1 development board
 - AM571x-IDK industrial board based on TI AM5718
 - i.MX6SX UDOO Neo
 - Boundary Devices Nitrogen6_SOM2 (i.MX6)
 - Engicam i.CoreM6
 - Grinn i.MX6UL liteSOM/liteBoard
 - Toradex Colibri iMX6 module
 
 Other changes:
 - added peripherals on renesas, davinci, stm32f429, uniphier, sti,
   mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
   mvebu, allwinner, broadcom, exynos, zynq
 
 - Continued fixes for W=1 dtc warnings
 
 - The old STiH415/416 SoC support gets removed, these never made it into
   products and have served their purpose in the kernel as a template
   for teh newer chips from ST
 
 - The exynos4415 dtsi file is removed as nothing uses it.
 
 - Intel PXA25x can now be booted using devicetree
 
 Conflicts:

Linus Torvalds 3bd776bbda ARM: SoC 64-bit changes for v4.9
Changes to platform code for 64-bit ARM platforms. We are not adding
 any new platforms that require code or Kconfig changes this time, so
 it's basically just defconfig changes to enable support for more
 drivers used on the existing platforms.
 
 This is mainly interesting for the Raspberry Pi 3, which should
 now work much better with the default build.

Linus Torvalds 3ec5e8d82b ARM: SoC non-urgent fixes for v4.10
As usual, we queue up a few fixes that don't seem urgent enough to go in
 through -rc, or that just came a little too late given their size.
 
 The zx fixes make the platform finally boot on real hardware, the
 davinci and imx31 get the DT support working better for some of
 the machines that are still normally used with classic board files.
 One tegra fix is important for new bootloader versions, but the
 bug has been around for a while without anyone noticing.
 
 The other changes are mostly cosmetic.

Merge tag 'pci-v4.10-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci

Pull PCI updates from Bjorn Helgaas:
 "PCI changes:

   - add support for PCI on ARM64 boxes with ACPI. We already had this
     for theoretical spec-compliant hardware; now we're adding quirks
     for the actual hardware (Cavium, HiSilicon, Qualcomm, X-Gene)

   - add runtime PM support for hotplug ports

   - enable runtime suspend for Intel UHCI that uses platform-specific
     wakeup signaling

   - add yet another host bridge registration interface. We hope this is
     extensible enough to subsume the others

   - expose device revision in sysfs for DRM

   - to avoid device conflicts, make sure any VF BAR updates are done
     before enabling the VF

   - avoid unnecessary link retrains for ASPM

   - allow INTx masking on Mellanox devices that support it

   - allow access to non-standard VPD for Chelsio devices

   - update Broadcom iProc support for PAXB v2, PAXC v2, inbound DMA,
     etc

   - update Rockchip support for max-link-speed

   - add NVIDIA Tegra210 support

   - add Layerscape LS1046a support

   - update R-Car compatibility strings

   - add Qualcomm MSM8996 support

   - remove some uninformative bootup messages"
