Pull staging driver updates from Greg KH:
"Here is the big set of staging driver updates for 7.2-rc1.
Nothing major in here, just constant grind of tiny cleanups and coding
style fixes and wrapper removals. Overall more code was removed than
added, always a nice sign that things are progressing forward.
Changes outside of drivers/staging/ was due to the octeon driver
changes, which for some reason also lives partially in the mips
subsystem, someday that all will be untangled and cleaned up, or just
removed entirely, it's hard to tell which is going to be its fate.
Other than octeon driver cleanups, in here are the usual:
- rtl8723bs driver reworking and cleanups, being the bulk of this
merge window given all of the issues and wrappers involved in that
beast of a driver
- most driver cleanups
- sm750fb driver cleanups (which might be done, as this really should
be moved to the drm layer one of these days...)

The driver allocates domain generic chips using
irq_alloc_domain_generic_chips() during probe and sets up chained
handlers using irq_set_chained_handler_and_data(). However, on driver
removal, the generic chips are not freed and the chained handlers are
not removed.
The generic chips remain on the global gc_list and may later be accessed by
generic interrupt chip suspend, resume, or shutdown callbacks after the
driver has been removed, potentially resulting in a use-after-free and
kernel crash.
The chained handlers that were installed in probe for peripheral and
syswake interrupts are also left dangling, which can lead to spurious
interrupts accessing freed memory.
Fix these issues by:
- Setting IRQ_DOMAIN_FLAG_DESTROY_GC flag in domain->flags, so the
core code automatically removes generic chips when irq_domain_remove()
is called
- Clearing all chained handlers with NULL in pdc_intc_remove()

Pull firewire updates from Takashi Sakamoto:
- firewire drivers have been able to assign an arbitrary value in the
mod_device entry, which is typed as kernel_ulong_t.
While storing the pointer value is legitimate, conversion back to a
pointer has been performed without preserving the const qualifier.
Uwe Kleine-König introduced an union to provide safer and more robust
conversions, as part of the ongoing CHERI enhancement work for ARM
and RISC-V architectures. This includes changes to the sound
subsystem, since the conversion pattern is widely used in ALSA
firewire stack.
- Userspace applications can request the core function to perform
isochronous resource management procedures. Dingsoul reported a
reference-count leak when these procedures are processed in workqueue
contexts.
This refactors the relevant code paths following a divide and conquer
approach. Consequently, it became clear that the issue still remain
in the path when userspace applications delegate automatic resource
reallocation after bus resets to the core.
In practice, the leak is rarely triggered, and a complete fix is
still in progress.

crossbar_domain_free() resets the domain data and then uses the nulled
out irq_data->hwirq member as index to reset the irq_map[] entry and to
write the relevant crossbar register with a safe entry. That means it
never frees the correct index and keeps the crossbar register connection
to the source interrupt active.
If it would not reset the domain data, then this would be even worse as
irq_data->hwirq holds the source interrupt number, but both the map and
register index need the corresponding GIC SPI number and not the source
interrupt number. This might even result in an out of bounds access as
the source interrupt number can be higher than the maximal index space.
Fix this by using the GIC SPI index from the parent domain's irq_data.

The primary interrupt handler (imx_mu_isr()) no longer invokes any
callbacks it only masks the interrupt source and returns. In a
forced-threaded environment the IRQ-core will force-thread the primary
handler which can be avoided.
The primary handler uses a spinlock_t to protect the RMW operation in
imx_mu_xcr_rmw() - nothing that may introduce long latencies.
The lock can be turned into a raw_spinlock_t and then the primary
handler can run in hardirq context even on PREEMPT_RT skipping one
thread.
Make struct imx_mu_priv::xcr_lock a raw_spinlock_t and skip
force-threading the primrary handler by marking it IRQF_NO_THREAD.

Move RX callback handling into the threaded handler. This is similar to
the TX side except that we explicitly mask the source interrupt in the
primary handler and unmask it in the threaded handler again after
success. This was done automatically in the TX part.
The masking/ unmasking can be removed from imx_mu_specific_rx() since it
already happens in the primary/ threaded handler before invoking the
channel specific callback.

Split the mailbox irq handling into a primary handler (imx_mu_isr()) and
a threaded handler (imx_mu_isr_th()). The primary handler masks the
interrupt event so the threaded handler can run without raising the
interrupt again.
The goal here is to invoke the mailbox core functions (such as
mbox_chan_received_data(), mbox_chan_txdone()) in preemptible context which is
made possible by using an threaded interrupt handler. This in turn means that
mailbox's client callbacks are invoked in preemptible context, too. This then
allows the mailbox client callback to skip an indirection via a workqueue if
it requries preemptible callback.
As a first step, prepare the logic and move TX handling part.

imx_mu_specific_rx() masks channel 0 and unmasks it again at the end of
the function. Given that at startup the channel index got unmasked it
should do the right job.
This here either unmasks the actual channel or another one but should
have no impact given that it reverses its doing at the end.
Peng Fan commented here:
| For specific rx channel, whether it is i.MX8 SCU or i.MX ELE, actually there is
| only 1 channel as of now, but it seems better to use cp->idx in case more
| channels in future.
Use the channel index instead of zero.

The driver uses of_platform_populate() but does not remove the added

followed by adding the module again.

sashiko complained about early usage of the device while probe isn't
completed. This can be mitigated by delaying the pm_runtime_enable()
into the removal path instead doing it early. This ensures that in an
error case the device is removed (and imx_mu_shutdown()) before
pm_runtime_disable() so we don't have to do this manually.
For the order to work, lets move devm_mbox_controller_register() until
after the pm-runtime part. So the reverse order will be mbox-controller
removal followed by disabling pm runtime.
Use devm_pm_runtime_enable(), remove manual pm_runtime_disable()
invocations and move the pm_runtime handling in probe before
devm_mbox_controller_register().

The RX event remains enabled because in this short window the RX event
was disabled in ->shutdown() while the interrupt was active and then
enabled again by the ISR while ->shutdown waited in free_irq().
This race requires timing and if happens can be problematic on shared
handlers if the "removed" channel triggers an interrupt. In this case
the irq-core will shutdown the interrupt with the "nobody cared"
message.
Introduce imx_mu_con_priv::shutdown to signal that the channel is
shutting down. This flag is set with the lock held (by
imx_mu_xcr_clr_shut()). The unmask side uses imx_mu_xcr_set_act() which
only enables the event if the channel has not been shutdown and
serialises on the same lock.

Commit 186d124f07da ("tpm_eventlog.c: fix binary_bios_measurements")
split the output to write the endian-converted event header first and
then the variable-length event data.
However, the split was at sizeof(struct tcpa_event) - 1, even though
event_data was a zero-length array, and later a flexible array member,
both of which already excluded the event data.
Therefore, the current code writes the first three bytes of event_size
from the endian-converted header and then the last byte from the raw
header, which can emit a corrupted event_size on PPC64, where
do_endian_conversion() maps to be32_to_cpu().
Split one byte later to write the full endian-converted header first,
followed by the variable-length event->event_data.

probe tpm_crb_ffa forcefully when it's built-in to integrate with IMA.
However, IMA now provides the IMA_INIT_LATE_SYNC build option, which
initialises IMA at the late_initcall_sync level, so this change is no
longer required.

tpm_buf_append_salt() in drivers/char/tpm/tpm2-sessions.c calls
crypto_kpp_generate_public_key() and crypto_kpp_compute_shared_secret()
without installing a completion callback, discards both return values,
and immediately frees the kpp_request via kpp_request_free(). When the
resolved ecdh-nist-p256 KPP backend is asynchronous (atmel-ecc, HPRE,
keembay-ocs), either operation returns -EINPROGRESS and the deferred
completion worker dereferences the freed request.
The path fires automatically from the hwrng_fillfn kernel thread via
tpm_get_random -> tpm2_get_random -> tpm2_start_auth_session ->
tpm_buf_append_salt on every entropy poll, without any userland action.
Install crypto_req_done as the completion callback, wrap both KPP
operations in crypto_wait_req(), and propagate errors to the caller.
The wait is a no-op for synchronous backends.

Some TPMs fail to grant locality when requested immediately after being
relinquished. In this case, the TPM_ACCESS_REQUEST_USE bit of the
TPM_ACCESS register is cleared immediately without setting
TPM_ACCESS_ACTIVE_LOCALITY.
This issue can be seen at boot since tpm_chip_start, called right
after locality is relinquished, will fail. This causes the probe to
fail:
tpm_tis MSFT0101:00: probe with driver tpm_tis failed with error -1
This occurs on some older Dell Latitudes. For the Nuvoton TPM used in
these machines, add a delay after locality is relinquished.

The entire 32 bit did_vid is read from the device, but only the 16 bit
vendor id portion was stored in the tpm_tis_data structure. Storing the
entire value allows the device id to be used to handle quirks. Printing
the vid and did in the error case also helps identify problem devices.

Every platform driver can be forced to match a device that doesn't match
its list of device IDs because of device_match_driver_override(), so
platform drivers that rely on the existence of a device's ACPI companion
object need to verify its presence.
Accordingly, add a requisite ACPI_COMPANION() check against NULL to the
tpm_crb driver.

wait_event_interruptible_timeout() evaluates its condition after setting
the current task state to TASK_INTERRUPTIBLE.
With CONFIG_DEBUG_ATOMIC_SLEEP this triggers a warning when the IRQ wait
path is used:
tpm_tis_status()
tpm_tis_spi_read_bytes()
tpm_tis_spi_transfer_full()
spi_bus_lock()
mutex_lock()
Address this with the following measures:
1. Call wait_tpm_stat_cond() only while tasking is running.
2. Use wait_woken() to wait for changes.

tpm_buf_append_name() supports callers passing a pre-computed name
for handles. When name is non-NULL, the code skips the
tpm2_read_public() path but leaves name_size_alg uninitialized
before it is used as the memcpy size argument.
No current in-tree caller passes a non-NULL name, but future use
cases such as name caching would exercise this path. Initialize
name_size_alg by calling name_size() on the caller-provided name,
sharing the error check and assignment with the existing
tpm2_read_public() path. This prevents unmasking a latent bug when
the non-NULL name path is eventually used.

Commit 207696b17f38 ("tpm: use a map for tpm2_calc_ordinal_duration()")
inadvertently reduced the timeout for TPM2 key creation commands
(`CREATE_PRIMARY`, `CREATE`, `CREATE_LOADED`) from 300 seconds to 30
seconds.
This causes intermittent timeout failures, with several failures observed
across hundreds of test runs on some Intel platforms using Infineon
SLB9670 and SLB9672 TPM modules. Restore the timeout to 300 seconds to
avoid spurious failures.

Remove some noise from the MM selftests build
- "mm: Free contiguous order-0 pages efficiently" (Ryan Roberts)
Speed up the freeing of a batch of 0-order pages by first scanning
them for coalescing opportunities. This is applicable to vfree() and
to the releasing of frozen pages
- "mm/damon: introduce DAMOS failed region quota charge ratio"
(SeongJae Park)
Address a DAMOS usability issue: The DAMOS quota often exhausts
prematurely because it charges for all memory attempted, causing slow
and inconsistent performance when actions fail on unreclaimable
memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing

Pull kvm updates from Paolo Bonzini:
"arm64:
This is a bit of an odd merge window on the KVM/arm64 front. There
is absolutely no new feature in the pull request. It is purely
fixes, because it is simply becoming too hard to review new stuff
when so many AI-fuelled fixes hit the list.
- Significant cleanup of the vgic-v5 PPI support which was merged in
7.1. This makes the code more maintainable, and squashes a couple
of bugs in the meantime
- Set of fixes for the handling of the MMU in an NV context,
particularly VNCR-triggered faults. S1POE support is fixed as well
- Large set of pKVM fixes, mostly addressing recurring issues around
hypervisor tracking of donated pages in obscure cases where the
donation could fail and leave things in a bizarre state
- Fixes for the so-called "lazy vgic init", which resulted in
sleeping operations in non-preemptible sections. This turned out to
be far more invasive than initially expected..
- Reduce the overhead of L1/L2 context switch by not touching the FP
registers
- Fix the way non-implemented page sizes are dealt with when a guest
insist on using them for S2 translation
- The usual set of low-impact fixes and cleanups all over the map
Loongarch:
- On a request for lazy FPU load, load all FPU state that the VM
supports instead of enabling only the part (FPU, LSX or LASX) that
caused the FPU load request
- Some enhancements about interrupt injection
- Some bug fixes and other small changes
RISC-V:
- Batch G-stage TLB flushes for GPA range based page table updates
- Convert HGEI line management to fully per-HART
- Fix missing CSR dirty marking when FWFT state updated via ONE_REG
- Fix stale FWFT feature exposure to Guest/VM
- Speed up dirty logging write faults using MMU rwlock and atomic PTE
updates using cmpxchg() for permission-only changes
- Use flexible array for APLIC IRQ state
- Use kvm_slot_dirty_track_enabled() for logging enable check on a
memslot
- Avoid skipping valid pages in kvm_riscv_gstage_wp_range()
- Avoid skipping valid pages in kvm_riscv_gstage_unmap_range()
- Use endian-specific __lelong for NACL shared memory
S390:
- KVM_PRE_FAULT_MEMORY support
- Support for 2G hugepages
- Support for the ASTFLEIE 2 facility
- Support for fast inject using kvm_arch_set_irq_inatomic
- Fix potential leak of uninitialized bytes
- A few more misc gmap fixes
x86:
- Generic support for the more granular permissions allowed by EPT,
namely "read" (which was previously usurping the U bit) and
separate execution bits for kernel and userspace
- Do not assume that all page tables start with U=1/W=1/NX=0 at the
root, as AMD GMET needs to have U=0 at the root
- Introduce common assembly macros for use within Intel and AMD
vendor-specific vmentry code. This touches the SPEC_CTRL handling,
which is now entirely done in assembly for Intel (by reusing the
AMD code that already existed), and register save/restore which
uses some macro magic to compute the offsets in the struct. Both of
these are preparatory changes for upcoming APX support
- Clean up KVM's register tracking and storage, primarily to prepare
for APX support, which expands the maximum number of GPRs from 16
to 32
- Keep a single copy of the PDPTRs rather than two, since
architecturally there is just one
- Handle EXIT_FASTPATH_EXIT_USERSPACE in vendor code to ensure vendor
code gets a chance to handle things like reaping the PML buffer
- Update KVM's view of PV async enabling if and only if the MSR write
fully succeeds
- Fix a variety of issues where the emulator doesn't honor
guest-debug state, and clean up related code along the way
- Synthesize EPT Violation and #NPF "error code" bits when injecting
faults into L1 that didn't originate in hardware (in which case the
VMCS/VMCB doesn't hold relevant information)
- Add support for virtualizing (well, emulating) AMD's flavor of
CPL>0 CPUID faulting
- Clean up the GPR APIs so that KVM's use of "raw" is consistent, and
fix a variety of minor bugs along the way
- Fix an OOB memory access due to not checking the VP ID when
handling a Hyper-V PV TLB flush for L2
- Fix a bug in the mediated PMU's handling of fixed counters that
allowed the guest to bypass the PMU event filter
- Allow userspace to return EAGAIN when handling SNP and TDX
hypercalls, so the KVM can forward a "retry" status code to the
guest, and reserve all unused error codes for future usage
- Overhaul the TDP MMU => S-EPT code to move as much S-EPT specific
logic as possible into the TDX code, and to funnel (almost) all
S-EPT updates into a single chokepoint. The motivation is largely
to prepare for upcoming Dynamic PAMT support, but the cleanups are
nice to have on their own
- Plug a hole in shadow page table handling, where KVM fails to
recursively zap nested EPT/NPT shadow page tables when the nested
hypervisor tears down its own EPT/NPT page tables from the bottom
up
x86 (Intel):
- Support for nested MBEC (Mode-Based Execute Control), see above in
the generic section; also run with MBEC enabled even for non-nested
mode
- Use the kernel's "enum pg_level" in the TDX APIs instead of the
TDX-Module's level definitions (which are 0-based)
- Rework the TDX memory APIs to not require/assume that guest memory
is backed by "struct page" (in prepartion for guest_memfd hugepage
support)
- Fix a largely benign bug where KVM TDX would incorrectly state it
could emulate several x2APIC MSRs
- Use the "safe" WRMSR API when proxying LBR MSR writes as the
to-be-written value is guest controlled and completely unvalidated
x86 (AMD):
- Support for nested GMET (Guest Mode Execution Trap), see above in
the generic section; also run with GMET enabled even for non-nested
mode
- Fixes and minor cleanups to GHCB handling, on top of the earlier
work already merged into 7.1-rc
- Ensure KVM's copy of CR0 and CR3 are up-to-date prior to invoking
fastpath handlers
- Add support for virtualizing gPAT (KVM previously just used L1's
PAT when running L2)
- Fix goofs where KVM mishandles side effects (e.g. single-step and
PMC updates) when emulating VMRUN
- Fix a variety of bugs in AVIC's handling of x2APIC MSR
interception, most notably where KVM didn't disable interception of
IRR, ISR, and TMR regs
- Add support for virtualizing Host-Only/Guest-Only bits in the
mediated PMU
- Don't advertise support for unusable VM types, and account for VM
types that are disabled by firmware, e.g. to mitigate security
vulnerabilities
- Rewrite the SEV {en,de}crypt debug ioctls as they were riddle with
bugs and unnecessarily complicated, and add comprehensive tests
- Clean up and deduplicate the SEV page pinning code
- Fix minor goofs related to writing back CPUID information after
firmware rejects a CPUID page for an SNP vCPU
Generic:
- Rename invalidate_begin() to invalidate_start() throughout KVM to
follow the kernel's nomenclature, e.g. for mmu_notifiers
- Use guard() to cleanup up various KVM+VFIO flows
- Minor cleanups
guest_memfd:
- Return -EEXIST instead of -EINVAL if userspace attempts to bind a
gmem range to multiple memslots, and fix the test that was supposed
to ensure KVM returns -EEXIST
- Treat memslot binding offsets and sizes as unsigned values to fix a
bug where KVM interprets a large "offset + size" as a negative
value and allows a nonsensical offset
- Use the inode number instead of the page offset for the NUMA
interleaving index to fix a bug where the effective index would
jump by two for consecutive pages (the caller also adds in the page
offset)
Selftests:
- Randomize the dirty log test's delay when reaping the bitmap on the
first pass, as always waiting only 1ms hid a KVM RISC-V bug as the
test reaped the bitmap before KVM could build up enough state to
hit the bug
- A pile of one-off fixes and cleanups"
