This is the first set of bugfixes for ARM SoCs, fixing a couple
of stability problems, mostly on TI OMAP and Rockchips platforms:
- OMAP2 hwmod clocks must be enabled in the correct order
- OMAP3 Wakeup from resume through PRM IRQ was unreliable
- One regression on OMAP5 caused by a kexec fix
- Rockchip ethernet needs some settings for stable operation on Rock64
- Rockchip based Chrombook Plus needs another clock setting for
stable display suspend/resume
- Rockchip based phyCORE-RK3288 was able to run at an invalid
CPU clock frequency
- Rockchip MMC link was sometimes unreliable
- Multiple fixes to avoid crashes in the Broadcom STB DPFE driver
Other minor changes include:
- Devicetree fixes for incorrect hardware description (rockchip,
omap, Gemini, amlogic)
- Some MAINTAINER file updates to correct email and git addresses
- Some fixes addressing 'make W=1' dtc warnings (broadcom, amlogic,
cavium, qualcomm, hisilicon, zx)
- Fixes for LTO-compilation (orion, davinci, clps711x)
- One fix for an incorrect Kconfig errata selection

Jon attempted to fix the amount of RAM on the BCM958625HR in commit
c53beb47f6 ("ARM: dts: NSP: Correct RAM amount for BCM958625HR board")
but it seems like we tripped over some poorly documented schematics.
The top-level page of the schematics says the board has 2GB, but when
you end-up scrolling to page 6, you see two chips of 4GBit (512MB) but
what the bootloader really initializes only 512MB, any attempt to use
more than that results in data aborts. Fix this again back to 512MB.

This stops the driver from trying to probe the ATA slave
interface. The vendor code enables the slave interface
but the driver in the vendor tree does not make use of
it.
Setting it to muxmode 0 disables the slave interface:
the hardware only has the master interface connected
to the one harddrive slot anyways.
Without this change booting takes excessive time, so it
is very annoying to end users.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve as a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

A section type mismatch warning shows up when building with LTO,
since orion_ge00_mvmdio_bus_name was put in __initconst but not marked
const itself:
include/linux/of.h: In function 'spear_setup_of_timer':
arch/arm/mach-spear/time.c:207:34: error: 'timer_of_match' causes a section type conflict with 'orion_ge00_mvmdio_bus_name'
static const struct of_device_id timer_of_match[] __initconst = {
^
arch/arm/plat-orion/common.c:475:32: note: 'orion_ge00_mvmdio_bus_name' was declared here
static __initconst const char *orion_ge00_mvmdio_bus_name = "orion-mii";
^
As pointed out by Andrew Lunn, it should in fact be 'const' but not
'__initconst' because the string is never copied but may be accessed
after the init sections are freed. To fix that, I get rid of the
extra symbol and rewrite the initialization in a simpler way that
assigns both the bus_id and modalias statically.
I spotted another theoretical bug in the same place, where d->netdev[i]
may be an out of bounds access, this can be fixed by moving the device
assignment into the loop.

Building with LTO revealed that three spi_board_info arrays are marked
__initconst, but not const:
arch/arm/mach-davinci/board-dm365-evm.c: In function 'dm365_evm_init':
arch/arm/mach-davinci/board-dm365-evm.c:729:30: error: 'dm365_evm_spi_info' causes a section type conflict with 'dm646x_edma_device'

This marks them const as well, as was originally intended.

The array of string pointers is put in __initconst, and the strings themselves
are marke 'const' but the the pointers are not, which caused a warning when
built with LTO:
arch/arm/mach-clps711x/board-dt.c:72:20: error: 'clps711x_compat' causes a section type conflict with 'feroceon_ids'
static const char *clps711x_compat[] __initconst = {
This marks the array itself const as well, which was certainly the
intention originally.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
and
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:
https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve as a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

Trying to boot an RK3328 box with an HS200-capable eMMC, I see said eMMC
fail to initialise as it can't run its tuning procedure, because the
sample clock is missing. Upon closer inspection, whilst the clock is
present in the DT, its name is subtly incorrect per the binding, so
__of_clk_get_by_name() never finds it. By inspection, the drive clock
suffers from a similar problem, so has never worked properly either.
This error has propagated across the 32-bit DTs too, so fix those up.

In banked-sr.c, we use a top-level '__asm__(".arch_extension virt")'
statement to allow compilation of a multi-CPU kernel for ARMv6
and older ARMv7-A that don't normally support access to the banked
registers.
This is considered to be a programming error by the gcc developers
and will no longer work in gcc-8, where we now get a build error:
/tmp/cc4Qy7GR.s:34: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_usr'
/tmp/cc4Qy7GR.s:41: Error: Banked registers are not available with this architecture. -- `mrs r3,ELR_hyp'

/tmp/cc4Qy7GR.s:76: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_abt'
Passign the '-march-armv7ve' flag to gcc works, and is ok here, because
we know the functions won't ever be called on pre-ARMv7VE machines.
Unfortunately, older compiler versions (4.8 and earlier) do not understand
that flag, so we still need to keep the asm around.
Backporting to stable kernels (4.6+) is needed to allow those to be built
with future compilers as well.

The pinmuxing was missing for I2C1 which was causing intermittent issues
with the PMIC which is connected to I2C1. The bootloader did not quite
configure the I2C1 either, so when running at 2.6MHz, it was generating
errors at times.

When exposing data access through debugfs, the correct
debugfs_create_*() functions must be used, depending on data type.
Remove all casts from data pointers passed to debugfs_create_*()
functions, as such casts prevent the compiler from flagging bugs.
Correct all wrong usage:
- clk.rate is unsigned long, not u32,
- clk.flags is u8, not u32, which exposed the successive
clk.rate_offset and clk.src_offset fields.

HS omaps use irq_save_secure_context() instead of irq_save_context()
so sar_base will never get initialized and irq_sar_clear() gets called
with a wrong address for HS omaps from irq_restore_context().
Starting with commit f4b9f40ae9 ("ARM: OMAP4+: Initialize SAR RAM
base early for proper CPU1 reset for kexec") we have it available,
and this ideally would been fixed with that commit already.

For platform_suspend_ops, the finish call is too late to re-enable wake
irqs and we need re-enable wake irqs on wake call instead.
Otherwise noirq resume for devices has already happened. And then
dev_pm_disarm_wake_irq() has already disabled the dedicated wake irqs
when the interrupt triggers and the wake irq is never handled.
For devices that are already in PM runtime suspended state when we
enter suspend this means that a possible wake irq will never trigger.
And this can lead into a situation where a device has a pending padconf
wake irq, and the device will stay unresponsive to any further wake
irqs.
This issue can be easily reproduced by setting serial console log level
to zero, letting the serial console idle, and suspend the system from
an ssh terminal. Then try to wake up the system by typing to the serial
console.
Note that this affects only omap3 PRM interrupt as that's currently
the only omap variant that does anything in omap_pm_wake().
In general, for the wake irqs to work, the interrupt must have either
IRQF_NO_SUSPEND or IRQF_EARLY_RESUME set for it to trigger before
dev_pm_disarm_wake_irq() disables the wake irqs.

When more than one GP timers are used as kernel system timers and the
corresponding nodes in device-tree are marked with the same "disabled"
property, then the "attr" field of the property will be initialized
more than once as the property being added to sys file system via
__of_add_property_sysfs().
In __of_add_property_sysfs(), the "name" field of pp->attr.attr is set
directly to the return value of safe_name(), without taking care of
whether it's already a valid pointer to a memory block. If it is, its
old value will always be overwritten by the new one and the memory block
allocated before will a "ghost", then a kmemleak happened.
That the same "disabled" property being added to different nodes of device
tree would cause that kind of kmemleak overhead, at least once.
To fix it, allocate the property dynamically, and delete static one.

A new feature of SMCCC 1.1 is that it offers firmware-based CPU
workarounds. In particular, SMCCC_ARCH_WORKAROUND_1 provides
BP hardening for CVE-2017-5715.
If the host has some mitigation for this issue, report that
we deal with it using SMCCC_ARCH_WORKAROUND_1, as we apply the
host workaround on every guest exit.

The new SMC Calling Convention (v1.1) allows for a reduced overhead
when calling into the firmware, and provides a new feature discovery
mechanism.
Make it visible to KVM guests.

As we're about to update the PSCI support, and because I'm lazy,
let's move the PSCI include file to include/kvm so that both
ARM architectures can find it.

KVM doesn't follow the SMCCC when it comes to unimplemented calls,
and inject an UNDEF instead of returning an error. Since firmware
calls are now used for security mitigation, they are becoming more
common, and the undef is counter productive.
Instead, let's follow the SMCCC which states that -1 must be returned
to the caller when getting an unknown function number.

cache objects. This is good, but still leaves a lot of kernel memory
available to be copied to/from userspace in the face of bugs. To further
restrict what memory is available for copying, this creates a way to
whitelist specific areas of a given slab cache object for copying to/from
userspace, allowing much finer granularity of access control. Slab caches
that are never exposed to userspace can declare no whitelist for their
objects, thereby keeping them unavailable to userspace via dynamic copy
operations. (Note, an implicit form of whitelisting is the use of constant
sizes in usercopy operations and get_user()/put_user(); these bypass all
hardened usercopy checks since these sizes cannot change at runtime.)
This new check is WARN-by-default, so any mistakes can be found over the
next several releases without breaking anyone's system.

- remove %p and improve reporting with offset
- prepare infrastructure and whitelist kmalloc
- update VFS subsystem with whitelists
- update SCSI subsystem with whitelists

- update process memory with whitelists

to the clk rate protection support added by Jerome Brunet. This feature
will allow consumers to lock in a certain rate on the output of a clk so
that things like audio playback don't hear pops when the clk frequency
changes due to shared parent clks changing rates. Currently the clk
API doesn't guarantee the rate of a clk stays at the rate you request
after clk_set_rate() is called, so this new API will allow drivers
to express that requirement. Beyond this, the core got some debugfs
pretty printing patches and a couple minor non-critical fixes.
Looking outside of the core framework diff we have some new driver
additions and the removal of a legacy TI clk driver. Both of these hit
high in the dirstat. Also, the removal of the asm-generic/clkdev.h file
causes small one-liners in all the architecture Kbuild files. Overall, the
driver diff seems to be the normal stuff that comes all the time to
fix little problems here and there and to support new hardware.
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals
- Qualcomm Alpha PLL variants
- Divider code was using container_of() on bad pointers
- Allwinner DE2 clks on H3
- Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
- Mediatek clk driver compile test support
- AT91 PMC clk suspend/resume restoration support
- PLL issues fixed on si5351
- Broadcom IProc PLL calculation updates
- DVFS support for Armada mvebu CPU clks
- Allwinner fixed post-divider support
- TI clkctrl fixes and support for newer SoCs

high in the dirstat. Also, the removal of the asm-generic/clkdev.h
file causes small one-liners in all the architecture Kbuild files.
Overall, the driver diff seems to be the normal stuff that comes all
the time to fix little problems here and there and to support new
hardware.
Summary:
Core:
- Clk rate protection
- Symbolic clk flags in debugfs output
- Clk registration enabled clks while doing bookkeeping updates
New Drivers:
- Spreadtrum SC9860
- HiSilicon hi3660 stub
- Qualcomm A53 PLL, SPMI clkdiv, and MSM8916 APCS
- Amlogic Meson-AXG
- ASPEED BMC
Removed Drivers:
- TI OMAP 3xxx legacy clk (non-DT) support
- asm*/clkdev.h got removed (not really a driver)
Updates:
- Renesas FDP1-0 module clock on R-Car M3-W
- Renesas LVDS module clock on R-Car V3M
- Misc fixes to pr_err() prints
- Qualcomm MSM8916 audio fixes
- Qualcomm IPQ8074 rounded out support for more peripherals
- Qualcomm Alpha PLL variants
- Divider code was using container_of() on bad pointers
- Allwinner DE2 clks on H3
- Amlogic minor data fixes and dropping of CLK_IGNORE_UNUSED
- Mediatek clk driver compile test support
- AT91 PMC clk suspend/resume restoration support
- PLL issues fixed on si5351
- Broadcom IProc PLL calculation updates
- DVFS support for Armada mvebu CPU clks
- Allwinner fixed post-divider support
- TI clkctrl fixes and support for newer SoCs"
