KASAN uses the routines in stacktrace.c to capture the call stack each
time memory gets allocated or freed. Some of these routines are also
used to log CPU and memory context when exceptions are taken, and so
in some cases, memory accesses may be made that are not strictly in
line with the KASAN constraints, and may therefore trigger false KASAN
positives.
So follow the example set by other architectures, and simply disable
KASAN instrumentation for these routines.

According to the datasheet (Rev. 1.9) the RTL8211F requires at least
72ms "for internal circuits settling time" before accessing the PHY
registers. On similar boards with the same PHY this fixes an issue where
Ethernet link would not come up when using ip link set down/up.

These definitions are evidently left over from the days when
sparsemem settings were platform specific. This was no longer
the case when the platform got merged.
There was no warning in the past, but now the asm/sparsemem.h
header ends up being included indirectly, causing this warning:
In file included from /git/arm-soc/arch/arm/mach-keystone/keystone.c:24:
arch/arm/mach-keystone/memory.h:10:9: warning: 'SECTION_SIZE_BITS' macro redefined [-Wmacro-redefined]

We can fix this by removing the ZSMALLOC_PGTABLE_MAPPING feature (which
contains the offending calling code) from zsmalloc.
Even though this option showed some amount improvement(e.g., 30%) in
some arm32 platforms, it has been headache to maintain since it have
abused APIs[1](e.g., unmap_kernel_range in atomic context).
Since we are approaching to deprecate 32bit machines and already made
the config option available for only builtin build since v5.8, lastly it
has been not default option in zsmalloc, it's time to drop the option
for better maintenance.

ARM Cortex-A57 and Cortex-A72 cores running in 32-bit mode are affected
by silicon errata #1742098 and #1655431, respectively, where the second
instruction of a AES instruction pair may execute twice if an interrupt
is taken right after the first instruction consumes an input register of
which a single 32-bit lane has been updated the last time it was modified.
This is not such a rare occurrence as it may seem: in counter mode, only
the least significant 32-bit word is incremented in the absence of a
carry, which makes our counter mode implementation susceptible to these
errata.
So let's shuffle the counter assignments around a bit so that the most
recent updates when the AES instruction pair executes are 128-bit wide.

CAN0 and CAN1 instances share the same message ram configured

According to current configuration of CAN0, we need 0x1c00 bytes
so that the CAN1 don't overlap its message ram:
64 x RX FIFO0 elements => 64 x 72 bytes
32 x TXE (TX Event FIFO) elements => 32 x 8 bytes
32 x TXB (TX Buffer) elements => 32 x 72 bytes
So a total of 7168 bytes (0x1C00).
Fix offset to match this needed size.

Currently, '--orphan-handling=warn' is spread out across four different
architectures in their respective Makefiles, which makes it a little
unruly to deal with in case it needs to be disabled for a specific
linker version (in this case, ld.lld 10.0.1).
To make it easier to control this, hoist this warning into Kconfig and
the main Makefile so that disabling it is simpler, as the warning will
only be enabled in a couple places (main Makefile and a couple of
compressed boot folders that blow away LDFLAGS_vmlinx) and making it
conditional is easier due to Kconfig syntax. One small additional
benefit of this is saving a call to ld-option on incremental builds
because we will have already evaluated it for CONFIG_LD_ORPHAN_WARN.
To keep the list of supported architectures the same, introduce
CONFIG_ARCH_WANT_LD_ORPHAN_WARN, which an architecture can select to
gain this automatically after all of the sections are specified and size
asserted. A special thanks to Kees Cook for the help text on this
config.

Linux now has incomplete support for the LED controller on Turris Omnia:
it can set brightness and colors for each LED.
The controller can also put these LEDs into HW controlled mode, in which
the LEDs are controlled by HW: for example the WAN LED is connected via
MCU to the WAN PHY LED pin.
The driver does not support these HW controlled modes yet, and on probe
puts the LEDs into SW controlled mode.
Add node describing the LED controller, but disable it for now.

Turris Omnia has an SFP cage that, together with WAN PHY, is connected
to eth2 SerDes via a SerDes multiplexor. When a SFP module is present,
the multiplexor switches the SerDes signal from PHY to SFP.
Describe the SFP cage, but leave it disabled. Until phylink has support
for such configuration, we are leaving it to U-Boot to enable SFP and
disable WAN PHY at boot time depending on whether a SFP module is
present.

Pull ARM SoC fixes from Arnd Bergmann:
"Another set of patches for devicetree files and Arm SoC specific
drivers:
- A fix for OP-TEE shared memory on non-SMP systems
- multiple code fixes for the OMAP platform, including one regression
for the CPSW network driver and a few runtime warning fixes
- Some DT patches for the Rockchip RK3399 platform, in particular
fixing the MMC device ordering that recently became
nondeterministic with async probe.
- Multiple DT fixes for the Tegra platform, including a regression
fix for suspend/resume on TX2
- A regression fix for a user-triggered fault in the NXP dpio driver
- A regression fix for a bug caused by an earlier bug fix in the
xilinx firmware driver
- Two more DTC warning fixes
- Sylvain Lemieux steps down as maintainer for the NXP LPC32xx
platform"

Merge tag 'omap-for-v5.10/fixes-rc5-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes
Fixes for omaps for various issues noticed during the -rc cycle:
- Earlier omap4 cpuidle fix was incomplete and needs to use a
configured idle state instead
- Fix am4 cpsw driver compatible to avoid invalid resource error
for the legacy driver
- Two kconfig fixes for genpd support that we added for for v5.10
for proper location of the option and adding missing option
- Fix ti-sysc reset status checking on enabling modules to ignore
quirky modules with reset status only usable when the quirk is
activated during reset. Also fix bogus resetdone warning for
cpsw and modules with no sysst register reset status bit
- Suppress a ti-sysc warning for timers reserved as system timers
- Fix the ordering of clocks for dra7 m_can

The current CPU thermal limit is a bit inappropriate for Nexus 7 once
device is getting used on a daily bases. For example, currently it's may
be impossible to watch a hardware accelerated 720p video without hitting
a severe CPU throttling, which ruins user experience. This patch improves
the thermal throttling thresholds.
In my experience setting CPU thermal threshold to 57C provides the most
reasonable result, where device is a bit warm under constant load and
not getting overly hot, in the same time performance is okay. Let's bump
the passive-cooling threshold from 50C to 57C and also lower the thermal
hysteresis to 0.2C in order to make throttling more reactive.

The actual syscon-reboot-mode child node can be added by a board.dts or

compatible needs to include simple-mfd. The binding now specifies this,

This patch adds support for STUSB1600 USB Type-C port controller, used on
I2C4 on stm32mp15xx-dkx.
The default configuration on this board, on Type-C connector, is:
- Dual Power Role (DRP), so set power-role to "dual";
- Vbus limited to 500mA, so set typec-power-opmode to "default" (it means
500mA in USB 2.0).
typec-power-opmode is used to reconfigure the STUSB1600 advertising of
current capability when its NVM is not in line with the board layout.
On stm32mp15xx-dkx, Vbus power source of STUSB1600 is 5V_VIN. So power
operation mode depends on the power supply used. To avoid any power
issues, it is better to limit Vbus to 500mA on this board.
ALERT# is the interrupt pin of STUSB1600. It needs an external pull-up, and
signal is active low.
USB OTG controller ID and Vbus signals are not connected on stm32mp15xx-dkx
boards, so disconnection are not detected.
Without DWC2 usb-role-switch:
- if you unplug the USB cable from the Type-C port, you have to manually
disconnect the USB gadget:
echo disconnect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect
- Then you can plug the USB cable again in the Type-C port, and manually
reconnect the USB gadget:
echo connect > /sys/devices/platform/soc/49000000.usb-otg/udc/49000000.usb-otg/soft_connect
With DWC2 usb-role-switch, USB gadget is dynamically disconnected or connected.

Previously we were not clearing non-uapi flag bits in
sigaction.sa_flags when storing the userspace-provided sa_flags or
when returning them via oldact. Start doing so.
This allows userspace to detect missing support for flag bits and
allows the kernel to use non-uapi bits internally, as we are already
doing in arch/x86 for two flag bits. Now that this change is in
place, we no longer need the code in arch/x86 that was hiding these
bits from userspace, so remove it.
This is technically a userspace-visible behavior change for sigaction, as
the unknown bits returned via oldact.sa_flags are no longer set. However,
we are free to define the behavior for unknown bits exactly because
their behavior is currently undefined, so for now we can define the
meaning of each of them to be "clear the bit in oldact.sa_flags unless
the bit becomes known in the future". Furthermore, this behavior is
consistent with OpenBSD [1], illumos [2] and XNU [3] (FreeBSD [4] and
NetBSD [5] fail the syscall if unknown bits are set). So there is some
precedent for this behavior in other kernels, and in particular in XNU,
which is probably the most popular kernel among those that I looked at,
which means that this change is less likely to be a compatibility issue.

Most architectures with the exception of alpha, mips, parisc and
sparc use the same values for these flags. Move their definitions into
asm-generic/signal-defs.h and allow the architectures with non-standard
values to override them. Also, document the non-standard flag values
in order to make it easier to add new generic flags in the future.
A consequence of this change is that on powerpc and x86, the constants'
values aside from SA_RESETHAND change signedness from unsigned
to signed. This is not expected to impact realistic use of these
constants. In particular the typical use of the constants where they
are or'ed together and assigned to sa_flags (or another int variable)
would not be affected.
