Commit e5fabbe43f3f ("pinctrl: mediatek: paris: Support generic
PIN_CONFIG_DRIVE_STRENGTH_UA") added support for using
drive-strength-microamp instead of mediatek,drive-strength-adv.
Since there aren't any users of mediatek,drive-strength-adv on mt8192
yet, remove this property and add drive-strength-microamp in its place,
which has a clearer meaning.
Fixes: 4ac68333ff6d ("dt-bindings: pinctrl: mt8192: Add mediatek,drive-strength-adv property")

The XP-PEN Deco L (UGEE) needs to be initialized by sending a buffer of
magic data, discovered by sniffing the Windows driver traffic.
In order to differentiate UGEE tablets that need this kind of
initialization from the previous ones, name them v2 internally and
create an entry point for them.
After initialization, the template report descriptors can be discovered
by parsing a string descriptor, similar to the one exposed by HUION v1
devices.
Add all the required elements to support the device.

When handling userspace MSR filter updates, recompute interception for
possible passthrough MSRs if and only if KVM wants to disabled
interception. If KVM wants to intercept accesses, i.e. the associated
bit is set in vmx->shadow_msr_intercept, then there's no need to set the
intercept again as KVM will intercept the MSR regardless of userspace's
wants.
No functional change intended, the call to vmx_enable_intercept_for_msr()
really is just a gigantic nop.

Wrap the manipulation of @role and the manual mutex_{release,acquire}()
invocations in CONFIG_PROVE_LOCKING=y to squash a clang-15 warning. When
building with -Wunused-but-set-parameter and CONFIG_DEBUG_LOCK_ALLOC=n,
clang-15 seees there's no usage of @role in mutex_lock_killable_nested()
and yells. PROVE_LOCKING selects DEBUG_LOCK_ALLOC, and the only reason
KVM manipulates @role is to make PROVE_LOCKING happy.
To avoid true ugliness, use "i" and "j" to detect the first pass in the
loops; the "idx" field that's used by kvm_for_each_vcpu() is guaranteed
to be '0' on the first pass as it's simply the first entry in the vCPUs
XArray, which is fully KVM controlled. kvm_for_each_vcpu() passes '0'
for xa_for_each_range()'s "start", and xa_for_each_range() will not enter
the loop if there's no entry at '0'.

This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.
what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

The only user of io_req_complete32()-like functions is cmd
requests. Instead of keeping the whole complete32 family, remove them
and provide the extras in already added for inline completions
req->extra{1,2}. When fill_cqe_res() finds CQE32 option enabled
it'll use those fields to fill a 32B cqe.

We want just one function that will handle both normal cqes and 32B
cqes. Combine __io_fill_cqe_req() and __io_fill_cqe_req32(). It's still
not entirely correct yet, but saves us from cases when we fill an CQE of
a wrong size.

There are too many cqe filling helpers, kill __io_fill_cqe{32}_req(),
use __io_fill_cqe{32}_req_filled() instead, and then rename it. It'll
simplify fixing in following patches.

Appropriately change calls to {regmap/regmap_field}_update_bits()
with {regmap/regmap_field}_set_bits()
and {regmap/regmap_field}_clear_bits() for improved readability.

We have set/clear/test operations for regmap, but not for regmap_field yet.
So let's introduce regmap_field helpers too.
In many instances regmap_field_update_bits() is used for simple bit setting
and clearing. In these cases the last argument is redundant and we can
hide it with a static inline function.
This adds three new helpers for simple bit operations: set_bits,
clear_bits and test_bits (the last one defined as a regular function).

If system have some mirrored memory and mirrored feature is not specified
in boot parameter, the basic mirrored feature will be enabled and this will
lead to the following situations:
- memblock memory allocation prefers mirrored region. This may have some
unexpected influence on numa affinity.
- contiguous memory will be split into several parts if parts of them
is mirrored memory via memblock_mark_mirror().
To fix this, variable mirrored_kernelcore will be checked in
memblock_mark_mirror(). Mark mirrored memory with flag MEMBLOCK_MIRROR iff
kernelcore=mirror is added in the kernel parameters.

Commit 177e15f0c144 ("arm64: add the initrd region to the linear mapping explicitly")
remove all the flags of the memory used by initrd. This is fine since
MEMBLOCK_MIRROR is not used in arm64.
However with mirrored feature introduced to arm64, this will clear the mirrored
flag used by initrd, which will lead to error log printed by
find_zone_movable_pfns_for_nodes() if the lower 4G range has some non-mirrored
memory.
To solve this problem, only MEMBLOCK_NOMAP flag will be removed via
memblock_clear_nomap().

For a system only have limited mirrored memory or some numa node without
mirrored memory, the per node vmemmap page_structs prefer to allocate
memory from mirrored region, which will lead to vmemmap_verify() in
vmemmap_populate_basepages() report lots of warning message.
This patch change the frequency of "potential offnode page_structs" warning
messages to only once to avoid a very long print during bootup.

If system has mirrored memory, memblock will try to allocate mirrored
memory firstly and fallback to non-mirrored memory when fails, but if with
limited mirrored memory or some numa node without mirrored memory, lots of
warning message about memblock allocation will occur.
This patch ratelimit the warning message to avoid a very long print during
bootup.

Commit b05b9f5f9dcf ("x86, mirror: x86 enabling - find mirrored memory
ranges") introduce the efi_find_mirror() function on x86. In order to reuse
the API we make it public.
Arm64 can support mirrored memory too, so function efi_find_mirror() is added to
efi_init() to this support for arm64.
Since efi_init() is shared by ARM, arm64 and riscv, this patch will bring
mirror memory support for these architectures, but this support is only tested
in arm64.
