The cpu_has_saa feature macro was added along with Cavium Octeon CPU
support back in commit 5b3b16880f40 ("MIPS: Add Cavium OCTEON processor
support files to arch/mips/cavium-octeon.") but has never been used.

when it's not suitably configured.
- Set struct cacheinfo's cpu_map_populated field to true, indicating
that we filled in cache info detected from cop0 registers & avoiding
complaints about that info being (intentionally) missing in

ARM64 randdconfig builds regularly run into a build error, especially
when NUMA_BALANCING and SPARSEMEM are enabled but not SPARSEMEM_VMEMMAP:
#error "KASAN: not enough bits in page flags for tag"
The last-cpuid bits are already contitional on the available space, so
the result of the calculation is a bit random on whether they were
already left out or not.
Adding the kasan tag bits before last-cpuid makes it much more likely to
end up with a successful build here, and should be reliable for
randconfig at least, as long as that does not randomize NR_CPUS or
NODES_SHIFT but uses the defaults.
In order for the modified check to not trigger in the x86 vdso32 code
where all constants are wrong (building with -m32), enclose all the
definitions with an #ifdef.

The __SYSCALL macro's arguments are system call number,
system call entry name and number of arguments for the
system call.
Argument- nargs in __SYSCALL(nr, entry, nargs) is neither
calculated nor used anywhere. So it would be better to
keep the implementaion as __SYSCALL(nr, entry). This will
unifies the implementation with some other architetures
too.

Move all the platform data to devicetree.
The only bit dropped is the PWM beeper, which requires the PWM driver
to be updated. I figured it's okay to remove it here since it's really
a non-critical device, and it'll be re-introduced soon enough.
The other change is the CS line of the SPI is now set as active low. The
SPI core would have forced "active low" anyway, unless the 'spi-cs-high'
property is set.
In the process of moving to devicetree, we also switched to new drivers:
- We use the simple-audio-card and simple-amplifier drivers instead of
the custom ASoC code;
- We use the new Ingenic DRM driver coupled with the GiantPlus GPM940B0
DRM panel driver instead of the old framebuffer driver;
- We use the new jz4780-dma driver instead of the old jz4740-dma one;
- We use the ingenic-nand and jz4740-ecc drivers instead of the old
jz4740-nand driver;
- We use ingenic-battery instead of jz4740-battery;
- We use iio-hwmon instead of jz4740-hwmon;
- We use ingenic-iio instead of the old jz4740-adc MFD driver.

The Netgear R6200 v1 uses a BCM4718A1 SOC and a BCM4352/BCM4360 for 5GHz
wireless. This patch adds support for detecting this model board and
registers the 3 buttons.
I have tested that the device can boot kernels 4.14 and 4.19 under
OpenWRT.
There is one issue that the LEDs on the device are controlled by a
74HC164 that uses bit-banging instead of SPI so it isn't accessible to
the kernel without adding a workaround. Without any workaround the
device on boot will flash all LEDs once then the power LED will remain
amber as all other LEDs stay off.

This adds initial support for huge pages to 32-bit MIPS systems.
Systems with extended addressing enabled (EVA,XPA,Alchemy/Netlogic)
are not yet supported.
With huge pages enabled, this implementation will increase page table
memory overhead to match that of a 64-bit MIPS system. However, the
cache-friendliness of page table walks is not affected significantly.

In preparation for 32-bit MIPS huge page support.
EVA,XPA are extended-addressing modes for 32-bit MIPS systems. Because
huge pages aren't currently supported in 32-bit MIPS, this doesn't take
any features away from EVA,XPA-enabled systems. However, the soon-to-
come 32-bit MIPS huge page support doesn't yet support them.
This also disables CPU_SUPPORTS_HUGEPAGES for the small number of 32-bit
MIPS CPUs from Alchemy/Netlogic that support a custom 36-bit extended
addressing. It's unknown if they even support huge pages in hardware.

There's an intentional switch case fall-through in Cavium Octeon USB
code, which triggers compile errors with -Wimplicit-fallthrough due to
-Werror being enabled for arch/mips.
This can be encountered when building cavium_octeon_defconfig.
Fix the build issue by annotating the intentional fall-through.

kvm_compute_return_epc contains a switch statement with an intentional
fall-through from a case handling jal (jump and link) instructions to
one handling j (jump) instructions. With -Wimplicit-fallthrough this
triggers a compile error (due to -Werror being enabled for arch/mips).
This can be reproduced using malta_kvm_defconfig.
Fix this by annotating the intentional fall-through.

Because CONFIG_OF defined for MIPS, cacheinfo attempts to fill information
from DT, ignoring data filled by architecture routine. This leads to error
reported
cacheinfo: Unable to detect cache hierarchy for CPU 0
Way to fix this provided in
commit fac51482577d ("drivers: base: cacheinfo: fix x86 with
CONFIG_OF enabled")
Utilize same mechanism to report that cacheinfo set by architecture

side. The two main highlights in the core framework are the addition of an bulk
clk_get API that handles optional clks and an extra debugfs file that tells the
developer about the current parent of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is mostly
because that SoC has started converting to the clk_hw style of clk
registration. The next big update is in the Amlogic meson clk driver that
gained some support for audio, cpu, and temperature clks while fixing some PLL
issues. Finally, the biggest thing that stands out is the conversion of a large
part of the Allwinner sunxi-ng driver to the new clk parent scheme that uses
less strings and more pointer comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks here and
there to clk data along with the normal addition of a handful of new drivers
and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
Updates:
- Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers
- Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
- Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
- Add clks for new Exynos5422 Dynamic Memory Controller driver
- Clock definition for Exynos4412 Mali
- Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
- Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
- TI clock probing done from DT by default instead of firmware
- Fix Amlogic Meson mpll fractional part and spread sprectrum issues
- Add Amlogic meson8 audio clocks
- Add Amlogic g12a temperature sensors clocks
- Add Amlogic g12a and g12b cpu clocks
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas R-Car H3, M3-W, and M3-N

Architectures which support kprobes have very similar boilerplate around
calling kprobe_fault_handler(). Use a helper function in kprobes.h to
unify them, based on the x86 code.
This changes the behaviour for other architectures when preemption is
enabled. Previously, they would have disabled preemption while calling
the kprobe handler. However, preemption would be disabled if this fault
was due to a kprobe, so we know the fault was not due to a kprobe
handler and can simply return failure.
This behaviour was introduced in commit a980c0ef9f6d ("x86/kprobes:
Refactor kprobes_fault() like kprobe_exceptions_notify()")
