TCR2_ELx.E0POE is set during smp_init().
However, this bit is not reprogrammed when the CPU enters suspension and
later resumes via cpu_resume(), as __cpu_setup() does not re-enable E0POE
and there is no save/restore logic for the TCR2_ELx system register.
As a result, the E0POE feature no longer works after cpu_resume().
To address this, save and restore TCR2_EL1 in the cpu_suspend()/cpu_resume()
path, rather than adding related logic to __cpu_setup(), taking into account
possible future extensions of the TCR2_ELx feature.

# vmalloc_helpers_tags: try faulted
not ok 67 vmalloc_helpers_tags
Commit a06494adb7ef ("arm64: mm: use untagged address to calculate page index")
fixed a KASAN warning in the BPF subsystem by adding kasan_reset_tag() to
the index calculation. In the execmem flow:
bpf_prog_pack_alloc()
-> bpf_jit_alloc_exec()
-> execmem_alloc()
The returned address from execmem_vmalloc/execmem_cache_alloc is passed
through kasan_reset_tag(), so start has no tag while area->addr still
retains the original tag. The fix correctly handled this case by resetting
the tag on area->addr:
(start - (unsigned long)kasan_reset_tag(area->addr)) >> PAGE_SHIFT
However, in normal vmalloc paths, both start and area->addr have matching
tags(or no tags). Resetting only area->addr causes a mismatch when
subtracting a tagged address from an untagged one, resulting in an
incorrect index.
Fix this by resetting tags on both addresses in the index calculation.
This ensures correct results regardless of the tag state of either address.
Tested with KASAN KUnit tests under CONFIG_KASAN_GENERIC,
CONFIG_KASAN_SW_TAGS, and CONFIG_KASAN_HW_TAGS - all pass. Also verified
the original BPF KASAN warning from [1] is still fixed.

"snps,tx_de_emphasis*" properties
"snps,tx_de_emphasis" is supposed to be a u8, not a u32. Since it is big
endian, 0 will be read rather than 1. The DWC3 Linux driver simply ORs
the value if "snps,tx_de_emphasis_quirk" is set, so the 2 properties
have no effect. (The driver doesn't clear the field either which is
another problem).
"snps,gctl-reset-quirk" is not documented nor used in the driver, so
drop it as well.

i.MX8M Plus DHCOM
Add missing 'clocks' property to LAN8740Ai PHY node, to allow the PHY driver
to manage LAN8740Ai CLKIN reference clock supply. This fixes sporadic link
bouncing caused by interruptions on the PHY reference clock, by letting the
PHY driver manage the reference clock and assure there are no interruptions.
This follows the matching PHY driver recommendation described in commit
bedd8d78aba3 ("net: phy: smsc: LAN8710/20: add phy refclk in support")

On this SoM eqos is the primary ethernet interface, Ka-Ro fuses the
address for it in eth_mac1, eth_mac2 seems to be left unfused. In their
downstream u-boot they fetch it from eth_mac1 [1][2], by setting alias
of eqos to ethernet0, the driver then fetches the mac address based on
the alias number.
Set eqos to read from eth_mac1 instead of eth_mac2. Also set fec to
point at eth_mac2 as it may be fused later even though it is disabled
by default.
With this changed barebox is now capable of loading the correct address.

operation, it need sd card supply voltage to be lower than 0.5v and keep
over 1ms, otherwise, next time power back the sd card supply voltage to

When we exec a new task we forget to flush the set of locked GCS mode bits.
Since we do flush the rest of the state this means that if GCS is locked
the new task will be unable to enable GCS, it will be locked as being
disabled. Add the expected flush.

Since commit 7137a203b251 ("arm64/fpsimd: Permit kernel mode NEON with
IRQs off"), the only condition under which the fallback path is taken
for FP/SIMD preserve/restore across a EFI runtime call is when it is
called from hardirq or NMI context.
In practice, this only happens when the EFI pstore driver is called to
dump the kernel log buffer into a EFI variable under a panic, oops or
emergency_restart() condition, and none of these can be expected to
result in a return to user space for the task in question.
This means that the existing EFI-specific logic for preserving and
restoring SVE/SME state is pointless, and can be removed.
Instead, kill the task, so that an exceedingly unlikely inadvertent
return to user space does not proceed with a corrupted FP/SIMD state.
Also, retain the preserve and restore of the base FP/SIMD state, as that
might belong to kernel mode use of FP/SIMD. (Note that EFI runtime calls
are never invoked reentrantly, even in this case, and so any interrupted
kernel mode FP/SIMD usage will be unrelated to EFI)

TL;DR: checking force_pte_mapping() in arch_kfence_init_pool() is
sufficient
Commit ce2b3a50ad92 ("arm64: mm: Don't sleep in
split_kernel_leaf_mapping() when in atomic context") recently added
an arm64 implementation of arch_kfence_init_pool() to ensure that
the KFENCE pool is PTE-mapped. Assuming that the pool was not
initialised early, block splitting is necessary if the linear
mapping is not fully PTE-mapped, in other words if
force_pte_mapping() is false.
arch_kfence_init_pool() currently makes another check: whether
BBML2-noabort is supported, i.e. whether we are *able* to split
block mappings. This check is however unnecessary, because
force_pte_mapping() is always true if KFENCE is enabled and
BBML2-noabort is not supported. This must be the case by design,
since KFENCE requires PTE-mapped pages in all cases. We can
therefore remove that check.
The situation is different in split_kernel_leaf_mapping(), as that
function is called unconditionally regardless of the configuration.
If BBML2-noabort is not supported, it cannot do anything and bails
out. If force_pte_mapping() is true, there is nothing to do and it
also bails out, but these are independent checks.
Commit 53357f14f924 ("arm64: mm: Tidy up force_pte_mapping()")
grouped these checks into a helper, split_leaf_mapping_possible().
This isn't so helpful as only split_kernel_leaf_mapping() should
check both. Revert the parts of that commit that introduced the
helper, reintroducing the more accurate comments in
split_kernel_leaf_mapping().

The buffer provided to kernel_neon_begin() is only used if the task is
scheduled out while the FP/SIMD is in use by the kernel, or when such a
section is interrupted by a softirq that also uses the FP/SIMD.
IOW, this happens rarely, and even if it happened often, there is still
no reason for this buffer to be cleared beforehand, which happens
unconditionally, due to the use of a compound literal expression.
So define that buffer variable explicitly, and mark it as
__uninitialized so that it will not get cleared, even when
-ftrivial-auto-var-init is in effect.
This requires some preprocessor gymnastics, due to the fact that the
variable must be defined throughout the entire guarded scope, and the
expression
({ struct user_fpsimd_state __uninitialized st; &st; })
is problematic in that regard, even though the compilers seem to
permit it. So instead, repeat the 'for ()' trick that is also used in
the implementation of the guarded scope helpers.

Commit 9a7c987fb92b ("crypto: arm64/ghash - Use API partial block

ghash_do_simd_update(). As a result, ghash-neon now produces incorrect
outputs when the message length isn't divisible by 16 bytes. Fix this.
(I didn't notice this earlier because this code is reached only on CPUs
that support NEON but not PMULL. I haven't yet found a way to get
qemu-system-aarch64 to emulate that configuration.)

Analogically to the x86 commit 881a9c9cb785 ("bpf: Do not audit
capability check in do_jit()"), change the capable() call to
ns_capable_noaudit() in order to avoid spurious SELinux denials in audit
log.
The commit log from that commit applies here as well:
"""
The failure of this check only results in a security mitigation being
applied, slightly affecting performance of the compiled BPF program. It
doesn't result in a failed syscall, an thus auditing a failed LSM
permission check for it is unwanted. For example with SELinux, it causes
a denial to be reported for confined processes running as root, which
tends to be flagged as a problem to be fixed in the policy. Yet
dontauditing or allowing CAP_SYS_ADMIN to the domain may not be
desirable, as it would allow/silence also other checks - either going
against the principle of least privilege or making debugging potentially
harder.
Fix it by changing it from capable() to ns_capable_noaudit(), which
instructs the LSMs to not audit the resulting denials.

Merge the two ksimd scopes in the implementation of SM4-XTS to prevent

The ciphertext stealing logic in the AES-XTS implementation creates a
separate ksimd scope to call into the FP/SIMD core routines, and in some
cases (CONFIG_KASAN_STACK is one, but there might be others), the 528
byte kernel mode FP/SIMD buffer that is allocated inside this scope is
not shared with the preceding ksimd scope, resulting in unnecessary
stack bloat.
Considering that
a) the XTS ciphertext stealing logic is never called for block
encryption use cases, and XTS is rarely used for anything else,
b) in the vast majority of cases, the entire input block is processed
during the first iteration of the loop,
we can combine both ksimd scopes into a single one with no practical
impact on how often/how long FP/SIMD is en/disabled, allowing us to
reuse the same stack slot for both FP/SIMD routine calls.

in small chunks
- Fix guest page fault within HLV* instructions
- Flush VS-stage TLB after VCPU migration for Andes cores
s390:
- Always allocate ESCA (Extended System Control Area), instead of
starting with the basic SCA and converting to ESCA with the
addition of the 65th vCPU. The price is increased number of exits
(and worse performance) on z10 and earlier processor; ESCA was
introduced by z114/z196 in 2010
- VIRT_XFER_TO_GUEST_WORK support
- Operation exception forwarding support
- Cleanups
x86:
- Skip the costly "zap all SPTEs" on an MMIO generation wrap if MMIO
SPTE caching is disabled, as there can't be any relevant SPTEs to
zap
- Relocate a misplaced export
- Fix an async #PF bug where KVM would clear the completion queue
when the guest transitioned in and out of paging mode, e.g. when
handling an SMI and then returning to paged mode via RSM
- Leave KVM's user-return notifier registered even when disabling
virtualization, as long as kvm.ko is loaded. On reboot/shutdown,
keeping the notifier registered is ok; the kernel does not use the
MSRs and the callback will run cleanly and restore host MSRs if the
CPU manages to return to userspace before the system goes down
- Use the checked version of {get,put}_user()
- Fix a long-lurking bug where KVM's lack of catch-up logic for
periodic APIC timers can result in a hard lockup in the host
- Revert the periodic kvmclock sync logic now that KVM doesn't use a
clocksource that's subject to NTP corrections
- Clean up KVM's handling of MMIO Stale Data and L1TF, and bury the
latter behind CONFIG_CPU_MITIGATIONS
- Context switch XCR0, XSS, and PKRU outside of the entry/exit fast
path; the only reason they were handled in the fast path was to
paper of a bug in the core #MC code, and that has long since been
fixed
- Add emulator support for AVX MOV instructions, to play nice with
emulated devices whose guest drivers like to access PCI BARs with
large multi-byte instructions
x86 (AMD):
- Fix a few missing "VMCB dirty" bugs
- Fix the worst of KVM's lack of EFER.LMSLE emulation
- Add AVIC support for addressing 4k vCPUs in x2AVIC mode
- Fix incorrect handling of selective CR0 writes when checking
intercepts during emulation of L2 instructions
- Fix a currently-benign bug where KVM would clobber SPEC_CTRL[63:32]
on VMRUN and #VMEXIT
- Fix a bug where KVM corrupt the guest code stream when re-injecting
a soft interrupt if the guest patched the underlying code after the
VM-Exit, e.g. when Linux patches code with a temporary INT3
- Add KVM_X86_SNP_POLICY_BITS to advertise supported SNP policy bits
to userspace, and extend KVM "support" to all policy bits that
don't require any actual support from KVM
x86 (Intel):
- Use the root role from kvm_mmu_page to construct EPTPs instead of
the current vCPU state, partly as worthwhile cleanup, but mostly to
pave the way for tracking per-root TLB flushes, and elide EPT
flushes on pCPU migration if the root is clean from a previous
flush
- Add a few missing nested consistency checks
- Rip out support for doing "early" consistency checks via hardware
as the functionality hasn't been used in years and is no longer
useful in general; replace it with an off-by-default module param
to WARN if hardware fails a check that KVM does not perform
- Fix a currently-benign bug where KVM would drop the guest's
SPEC_CTRL[63:32] on VM-Enter
- Misc cleanups
- Overhaul the TDX code to address systemic races where KVM (acting
on behalf of userspace) could inadvertantly trigger lock contention
in the TDX-Module; KVM was either working around these in weird,
ugly ways, or was simply oblivious to them (though even Yan's
devilish selftests could only break individual VMs, not the host
kernel)
- Fix a bug where KVM could corrupt a vCPU's cpu_list when freeing a
TDX vCPU, if creating said vCPU failed partway through
- Fix a few sparse warnings (bad annotation, 0 != NULL)
- Use struct_size() to simplify copying TDX capabilities to userspace
- Fix a bug where TDX would effectively corrupt user-return MSR
values if the TDX Module rejects VP.ENTER and thus doesn't clobber
host MSRs as expected
Selftests:
- Fix a math goof in mmu_stress_test when running on a single-CPU
system/VM
- Forcefully override ARCH from x86_64 to x86 to play nice with
specifying ARCH=x86_64 on the command line
- Extend a bunch of nested VMX to validate nested SVM as well
- Add support for LA57 in the core VM_MODE_xxx macro, and add a test
to verify KVM can save/restore nested VMX state when L1 is using
5-level paging, but L2 is not
- Clean up the guest paging code in anticipation of sharing the core
logic for nested EPT and nested NPT
guest_memfd:
- Add NUMA mempolicy support for guest_memfd, and clean up a variety
of rough edges in guest_memfd along the way
- Define a CLASS to automatically handle get+put when grabbing a
guest_memfd from a memslot to make it harder to leak references
- Enhance KVM selftests to make it easer to develop and debug
selftests like those added for guest_memfd NUMA support, e.g. where
test and/or KVM bugs often result in hard-to-debug SIGBUS errors
- Misc cleanups
Generic:
- Use the recently-added WQ_PERCPU when creating the per-CPU
workqueue for irqfd cleanup
- Fix a goof in the dirty ring documentation
- Fix choice of target for directed yield across different calls to
kvm_vcpu_on_spin(); the function was always starting from the first
vCPU instead of continuing the round-robin search"

Pull gpio updates from Bartosz Golaszewski:
"There's one new driver, lots of various updates to existing ones, some
refactoring support for new models and misc tweaks and fixes.
The biggest new feature in GPIO core is adding support for managed,
enable-counted sharing of GPIO pins, something that - until now - was
only hacked around with the GPIOD_FLAGS_BIT_NONEXCLUSIVE request flag
which basically allowed drivers to "fight it out" for the descriptor
and provided no synchronization. It was enabled on Qualcomm platforms
(and thus is enabled on arm64 defconfig) and I plan on removing
GPIOD_FLAGS_BIT_NONEXCLUSIVE once all drivers using it are switched to
the new mechanism.
GPIO core:
- add proper support for shared GPIOs that's aiming to replace the
current sharing mechanism (which provides no synchronization ot
enable counting) and enable it for Qualcomm platforms
- improve the software node GPIO lookup by using the fwnode
representation instead of the software node's name which was prone
to bugs (GPIO controllers don't have to use the software node's
name as their kernel label)
- remove the last user of legacy-of-mm-gpiochip.h and drop the header
- move closer to removing the legacy gpio_request_one() routine
- rename some symbols for consistency
- shrink GPIO printk() helpers by reusing existing code
- remove some redundant kernel messages
- use min() instead of min_t() in GPIO ACPI code
- use system_percpu_wq instead of system_wq in GPIO character device
code
New drivers:
- add a driver for the QIXIS FPGA GPIO controller
Driver improvements:
- use modernized variants of power management macros across a wide
array of drivers in order to avoid having to use the __maybe_unused
attribute
- convert gpio-elkhartlake and reset-gpio to using the auxiliary bus
instead of the platform bus as they are not really described in
firmware
- use lock guards and update symbol prefixes in gpio-mmio
- support the bryx radio interface kit in gpio-mpsse + refactor the
driver
- use software nodes for configuring the reset-gpio driver, including
setting up the reference to the shared "reset" pin
- check and propagate the return value of gpiod_set_value() to
user-space in gpio-virtuser (this was previously not possible as
this function returned void)
- extend the gpio-regmap helper with more features (bypass cache for
aliased inputs, force writes for aliased data registers, add a new
configuration parameter)
- remove unneeded includes from gpio-aspeed and gpio-latch
- add support for Tegra410 to gpio-tegra186
- replace PCI-specific PM with generic device-level PM in gpio-bt8xx
- use dynamic GPIO range allocation in gpio-loongson-64bit
- improve handling of level-triggered interrupts in gpio-pca953x
- add suspend/resume support to gpio-fxl6408
- add support for more models to gpio-menz127
- optimize gpio-mvebu interrupt handling by avoiding unnecessary
calls to mvebu_gpio_irq_handler()
- make locking more consistent in gpio-grgpio
Device-tree bindings:
- document new NXP and Microchip models
Documentation:
- add a comprehensive compatibility and feature list for
gpio-pca953x, which is a great addition as it's probably the most
commonly used GPIO expander driver
- kernel-doc tweaks
Late fixes:
- use BYTE_CTRL_MODE for 2K2000/3000 models in gpio-loongson"

Pull drm updates from Dave Airlie:
"There was a rather late merge of a new color pipeline feature, that
some userspace projects are blocked on, and has seen a lot of work in
