The I2C1 bus on early mcbin hardware is mis-wired, swapping SCL and SDA.
Work around this by using the i2c-gpio driver instead. XXX Caught early

Add pwm-fan support for controlling the fan speed, which allows the fan
speed to be controlled via sysfs. Alternatively, users can also add
their cooling maps to DT which will be specific to the environment that
they house the Macchiatobin, as well as their fan setup. For example,
one may connect PWM controlled case fans to this connector, and use
the PWM signal to control the case fans.

Configure the Macchiatobin 10G PHY LED modes to correct their polarity.
We keep the existing LED behaviours, but switch their polarity to
reflect how they are connected. Tweak the LED modes as well to be:
left: off = no link
solid green = RJ45 link up (not SFP+ cage)
flash green = traffic
right: off = no link
solid green = 10G
solid yellow = 1G
flash green = 100M

Make arch_kunwind_consume_entry() as __always_inline otherwise the
compiler might not inline it and allow attaching probes to it.
Without this, just probing arch_kunwind_consume_entry() via
<tracefs>/kprobe_events will crash the kernel on arm64.
The crash can be reproduced using the following compiler and kernel
combination:

Commit 09896da07315 ("arm64: dts: qcom: msm8996: Hook up MPM") has
hooked up the MPM irq chip on the MSM8996 platform. However this causes
my Dragonboard 820c crash during bootup (usually when probing IOMMUs).
Revert the offending commit for now. Quick debug shows that making
tlmm's wakeup-parent point to the MPM is enough to trigger the crash.

Limit the WiFi PCIe link speed to Gen2 speed (500 MB/s), which is the
speed that the boot firmware has brought up the link at (and that
Windows uses).
This is specifically needed to avoid a large amount of link errors when
restarting the link during boot (but which are currently not reported).
This also appears to fix intermittent failures to download the ath11k
firmware during boot which can be seen when there is a longer delay
between restarting the link and loading the WiFi driver (e.g. when using
full disk encryption).

The bit-sliced implementation of AES-CTR operates on blocks of 128
bytes, and will fall back to the plain NEON version for tail blocks or
inputs that are shorter than 128 bytes to begin with.
It will call straight into the plain NEON asm helper, which performs all
memory accesses in granules of 16 bytes (the size of a NEON register).
For this reason, the associated plain NEON glue code will copy inputs
shorter than 16 bytes into a temporary buffer, given that this is a rare
occurrence and it is not worth the effort to work around this in the asm
code.
The fallback from the bit-sliced NEON version fails to take this into
account, potentially resulting in out-of-bounds accesses. So clone the
same workaround, and use a temp buffer for short in/outputs.

- A couple of USB-C connector DT description revert to fix regression
on imx8mp-dhcom-pdk3 and imx8mn-var-som-symphony board.
- Fix valid range check for imx-weim bus driver.
- Disable UART4 on Data Modul i.MX8M Plus eDM SBC to avoid boot hang
in case that RDC protection is in place.

The fields in SMCR_EL1 reset to an architecturally UNKNOWN value. Since we
do not otherwise manage the traps configured in this register at runtime we
need to reconfigure them after a suspend in case nothing else was kind
enough to preserve them for us. Do so for SMCR_EL1.EZT0.

This reverts commit f9daab0ad01cf9d165dbbbf106ca4e61d06e7fe8.
Geert reports that his particular GCC 5.5 vintage toolchain fails to
build an arm64 defconfig because of this change:
| arch/arm64/include/asm/jump_label.h:25:2: error: invalid 'asm':
| invalid operand
| asm goto(
^
Aopparently, this is something we claim to support, so let's revert back
to the old jump label constraint for now while discussions about raising
the minimum GCC version are ongoing.

Pull KVM fixes from Paolo Bonzini:
"ARM:
- Avoid dropping the page refcount twice when freeing an unlinked
page-table subtree.
- Don't source the VFIO Kconfig twice
- Fix protected-mode locking order between kvm and vcpus
RISC-V:
- Fix steal-time related sparse warnings
x86:
- Cleanup gtod_is_based_on_tsc() to return "bool" instead of an "int"
- Make a KVM_REQ_NMI request while handling KVM_SET_VCPU_EVENTS if
and only if the incoming events->nmi.pending is non-zero. If the
target vCPU is in the UNITIALIZED state, the spurious request will
result in KVM exiting to userspace, which in turn causes QEMU to
constantly acquire and release QEMU's global mutex, to the point
where the BSP is unable to make forward progress.
- Fix a type (u8 versus u64) goof that results in pmu->fixed_ctr_ctrl
being incorrectly truncated, and ultimately causes KVM to think a
fixed counter has already been disabled (KVM thinks the old value
is '0').
- Fix a stack leak in KVM_GET_MSRS where a failed MSR read from
userspace that is ultimately ignored due to ignore_msrs=true
doesn't zero the output as intended.
Selftests cleanups and fixes:
- Remove redundant newlines from error messages.
- Delete an unused variable in the AMX test (which causes build
failures when compiling with -Werror).
- Fail instead of skipping tests if open(), e.g. of /dev/kvm, fails
with an error code other than ENOENT (a Hyper-V selftest bug
resulted in an EMFILE, and the test eventually got skipped).
- Fix TSC related bugs in several Hyper-V selftests.
- Fix a bug in the dirty ring logging test where a sem_post() could
be left pending across multiple runs, resulting in incorrect
synchronization between the main thread and the vCPU worker thread.
- Relax the dirty log split test's assertions on 4KiB mappings to fix
false positives due to the number of mappings for memslot 0 (used
for code and data that is NOT being dirty logged) changing, e.g.
due to NUMA balancing"

Doug Anderson observed that ChromeOS crashes are being reported which
include failing allocations of order 7 during core dumps due to ptrace
allocating storage for regsets:
chrome: page allocation failure: order:7,
mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO),
nodemask=(null),cpuset=urgent,mems_allowed=0
...
regset_get_alloc+0x1c/0x28
elf_core_dump+0x3d8/0xd8c
do_coredump+0xeb8/0x1378
with further investigation showing that this is:
[ 66.957385] DOUG: Allocating 279584 bytes
which is the maximum size of the SVE regset. As Doug observes it is not
entirely surprising that such a large allocation of contiguous memory might
fail on a long running system.
The SVE regset is currently sized to hold SVE registers with a VQ of
SVE_VQ_MAX which is 512, substantially more than the architectural maximum
of 16 which we might see even in a system emulating the limits of the
architecture. Since we don't expose the size we tell the regset core
externally let's define ARCH_SVE_VQ_MAX with the actual architectural
maximum and use that for the regset, we'll still overallocate most of the
time but much less so which will be helpful even if the core is fixed to
not require contiguous allocations.
Specify ARCH_SVE_VQ_MAX in terms of the maximum value that can be written
into ZCR_ELx.LEN (where this is set in the hardware). For consistency
update the maximum SME vector length to be specified in the same style
while we are at it.
We could also teach the ptrace core about runtime discoverable regset sizes
but that would be a more invasive change and this is being observed in
practical systems.

The px30 has two spi controllers with two chip-selects each.
The num-cs property is specified as the total number of chip
selects a controllers has and is used since 2020 to find uses
of chipselects outside that range in the Rockchip spi driver.
Without the property set, the default is 1, so spi devices
using the second chipselect will not be created.
