soc: fixes for 7.1, part 2
Following the previous set of fixes, this addresses another significant
number of small issues found in firmware drivers (tee, optee, qcomtee,
qcom ice, exynos acpm) drivers through various tools. This is about
error handling, resource leaks, concurrency and a use-after-free bug.
The fixes for the Qualcomm ICE driver also introduce interface changes
in the UFS and MMC drivers using it.
Outside of firmware drivers, there are a few fixes across the tree:
- Minor driver code mistakes in the Atmel EBI memory controller,
the i.MX soc ID driver and socfpga boot logic
- A defconfig change to avoid a boot time regression on multiple
qualcomm boards
- Device tree fixes for qualcomm, at91 and gemini, addressing
mostly minor configuration mistakes

firmware: samsung: acpm: Fix infinite loop on sequence number exhaustion
Sashiko identified a possible infinite loop [1].
ACPM IPC sequence numbers are tracked via a 64-bit bitmap. Previously,
acpm_prepare_xfer() used a do...while loop to search for a free
sequence number.
If all 63 available sequence numbers are leaked due to transient
hardware timeouts or mailbox failures, the bitmap becomes full.
The next call to acpm_prepare_xfer() would enter an infinite loop.
Fix this by utilizing the kernel's optimized bitmap search functions
(find_next_zero_bit / find_first_zero_bit). If the pool is completely
exhausted, log the failure and return -EBUSY to allow the kernel to
fail gracefully instead of hanging.
Furthermore, drop the allocation loop entirely. Because
acpm_prepare_xfer() is strictly called under the 'tx_lock' mutex,
sequence number allocations are perfectly serialized. If
find_next_zero_bit() locates a free bit, a single
test_and_set_bit_lock() is mathematically guaranteed to succeed.
To enforce this locking invariant, wrap the allocation in a
WARN_ON_ONCE. If the atomic set fails, it indicates the driver's
mutex serialization is fundamentally broken. The warning generates a
stack trace for debugging, while returning -EIO immediately aborts the
transfer to prevent silent payload corruption.

firmware: samsung: acpm: Fix missing LKMM barriers in sequence allocator
Sashiko identified memory ordering races in [1].
The ACPM driver uses a globally shared 'bitmap_seqnum' to track
available sequence numbers. Even though threads now strictly free their
own sequence numbers, the allocation and freeing of these bits across
concurrent threads are effectively lockless operations and require
explicit LKMM memory barriers.
Previously, the driver used plain bitwise operators (test_bit, set_bit,
clear_bit), which lack ordering guarantees. This creates two race
conditions on weakly ordered architectures like ARM64:
1. Polling Release Violation: The polling thread copies its payload and
calls clear_bit(). Without a release barrier, the CPU can reorder
the memory operations, making the cleared bit globally visible
before the payload reads have fully completed.
2. TX Acquire Violation: The TX thread loops on test_bit(), calls
set_bit(), and then wipes the payload buffer via memset(). Without
an acquire barrier, the CPU can speculatively execute the memset()
before the bit is safely and formally claimed.
If these reorderings overlap, a new TX thread can claim the sequence
number and overwrite the buffer while the original polling thread is
still actively reading from it.
Fix this by upgrading the bitwise operators. Wrap the TX allocation in
test_and_set_bit_lock() to establish formal LKMM Acquire semantics, and
pair it with clear_bit_unlock() in the polling path to enforce Release
semantics.

firmware: samsung: acpm: Fix false timeouts and Use-After-Free in polling
Sashiko identified severe races in the polling state machine [1].
In the ACPM driver's polling mode, threads waited for responses by
monitoring the globally shared 'bitmap_seqnum'. This caused false
timeouts because if a thread processed its response and freed the
sequence number, a concurrent TX thread could immediately reallocate
it before the polling thread woke up.
Additionally, the driver suffered from a cross-thread Use-After-Free
(UAF) preemption race. Previously, acpm_get_rx() cleared the sequence
number of whichever RX message it drained from the hardware queue. This
meant Thread A could globally free Thread B's sequence slot while
Thread B was asleep. A new Thread C could then steal the slot,
overwrite the buffer, and leave Thread B to wake up to corrupted state
or a timeout.
Fix this by rewriting the polling state machine:
1. Decouple polling from the global allocator by introducing a per-slot
'completed' flag, synchronized via smp_store_release() and
smp_load_acquire().
2. Strip acpm_get_saved_rx() out of acpm_get_rx() to make it a pure
queue-draining function. Introduce a 'native_match' boolean argument
which evaluates to true only if the thread natively processed its
own sequence number during the call. This explicitly informs the
polling loop whether it must retrieve its payload from the
cross-thread cache.
3. Centralize the cache fallback and sequence number free (clear_bit)
inside the polling loop. Crucially, the free operation now strictly
targets the thread's own TX sequence number (xfer->txd[0]), rather
than the drained RX sequence number. This enforces strict ownership:
a thread only ever frees its own allocated sequence slot, and only
at the exact moment it completes its poll, eliminating the UAF
window.
Furthermore, explicitly guard the 'native_match' assignment with an
if (rx_seqnum == tx_seqnum) check, even for zero-length (no payload)
responses. While an unguarded assignment wouldn't crash (because the
cache fallback acpm_get_saved_rx() safely returns early on zero-length
transfers) doing so would "lie" to the state machine. If a thread
drained the queue and found another thread's zero-length message,
setting native_match = true would falsely convince the polling loop
that it natively handled its own response. Maintaining a rigorous state
machine requires that native_match is only set when a thread explicitly
processes its own sequence number.

efi/loongarch: Randomize kernel preferred address for KASLR
Introduce efi_get_kimg_kaslr_address() helper to compute the preferred kernel image load address dynamically when CONFIG_RANDOMIZE_BASE is enabled. The function derives a random offset by using the EFI-provided randomness combined with the timer tick value, and constrains it within CONFIG_RANDOMIZE_BASE_MAX_OFFSET. Update EFI_KIMG_PREFERRED_ADDRESS to call this helper so that the EFI stub can select a randomized load address when KASLR is active, while preserving the original base address behavior when KASLR is disabled or "nokaslr" is specified. Note: LoongArch can't KASLR for hibernation, so set efi_nokaslr to true if "resume=<devname>" is explicitly specified in cmdline.

firmware: samsung: acpm: Fix mailbox channel leak on probe error
Sashiko identified the leak at [1].
The ACPM driver allocates hardware mailbox channels using
`mbox_request_channel()` during `acpm_channels_init()`. However, the
driver lacked a `.remove` callback and did not free these channels on
subsequent error paths inside `acpm_probe()`.
Additionally, if `acpm_achan_alloc_cmds()` failed during the channel
initialization loop, the function returned immediately, bypassing the
manual cleanup and permanently leaking any channels successfully
requested in previous loop iterations.
Fix this by modifying `acpm_free_mbox_chans()` to match the `devres`
action signature and registering it via `devm_add_action_or_reset()`.

firmware: samsung: acpm: Fix cross-thread RX length corruption
Sashiko identified a cross-thread RX length corruption bug when
reviewing the thermal addition to ACPM [1].
When multiple threads concurrently send IPC requests, the ACPM polling
mechanism can encounter responses belonging to other threads. To drain
the queue, the driver saves these concurrent responses into an internal
cache (`rx_data->cmd`) to be retrieved later by the owning thread.
Previously, the driver incorrectly used `xfer->rxcnt` (the expected
receive length of the *current* polling thread) when copying data for
*other* threads into this cache. If the threads expected responses of
different lengths, this resulted in buffer underflows (leading to reads
of uninitialized memory) or potential buffer overflows.
Fix this by replacing the boolean `response` flag in
`struct acpm_rx_data` with `rxcnt`, caching the exact expected receive
length for each specific transaction during transfer preparation. Use
this cached length when saving concurrent responses.
Consequently, ensure that `xfer->rxcnt` is explicitly zeroed in driver
helpers (e.g., `acpm_dvfs_set_xfer`) for fire-and-forget messages to
prevent uninitialized stack garbage from being interpreted as a massive
expected receive length.

firmware: psci: Set pm_set_resume/suspend_via_firmware() for SYSTEM_SUSPEND
PSCI specification defines the SYSTEM_SUSPEND feature which enables the firmware to implement the suspend to RAM (S2RAM) functionality by transitioning the system to a deeper low power state. When the system enters such state, the power to the peripheral devices might be removed. So the respective device drivers must prepare for the possible removal of the power by performing actions such as shutting down or resetting the device in their system suspend callbacks. The Linux PM framework allows the platform drivers to convey this info to device drivers by calling the pm_set_suspend_via_firmware() and pm_set_resume_via_firmware() APIs. Hence, if the PSCI firmware supports SYSTEM_SUSPEND feature, call the above mentioned APIs in the psci_system_suspend_begin() and psci_system_suspend_enter() callbacks.

Both notification handlers currently look up a notifier callback under

Copy the callback pointer and callback data while notify_lock is

the target cpu. Routing that path back through smp_call_function_single()
re-enters the call-function IPI path and executes the notification

firmware: arm_ffa: Avoid collapsing NPI work from different CPUs
Notification pending interrupts are registered as per-CPU IRQs, but the driver queues all NPI handling through a single shared work_struct. That allows queue_work_on() calls from different CPUs to collapse onto a single pending work item even though the work function uses the CPU it runs on to fetch and handle per-CPU notifications. Move notif_pcpu_work into the per-CPU ffa_pcpu_irq state and initialize one work item per CPU. This keeps NPI handling independent per CPU and avoids losing notifications when multiple CPUs queue work concurrently.

firmware: arm_ffa: Skip free_pages on RX buffer alloc failure
If the RX buffer allocation fails in ffa_init(), the error path jumps to
free_pages even though no buffer has been allocated yet. Route that case
directly to free_drv_info so the cleanup path is only used after at
least one RX/TX buffer allocation has succeeded.

firmware: arm_ffa: Check for NULL FF-A ID table while driver registration
The bus match callback assumes that every FF-A driver provides an
id_table and dereferences it unconditionally. Enforce that contract at
registration time so a buggy client driver cannot crash the bus during
match.

efi/libstub: Synchronize instruction cache after kernel relocation
The relocated kernel image is copied to its new location using memcpy(). On architectures with separate instruction and data caches, the copied instructions may remain stale in the instruction cache, leading to the execution of outdated contents. Call efi_cache_sync_image() after the relocation copy to ensure the instruction cache is synchronized with the updated memory contents before control is transferred to the relocated kernel.

efi/libstub: Move efi_relocate_kernel() into its only remaining user
LoongArch is the only arch that still uses efi_relocate_kernel(), so before making changes to it that LoongArch needs, turn it into a private function. Move efi_low_alloc_above() into mem.c while at it, and drop the relocate.c source file altogether.

efi: pstore: Drop efivar lock when efi_pstore_open() returns with an error
If kzalloc fails, the function returns -ENOMEM without calling
efivar_unlock(). Since open() returned an error, the calling site
in pstore_get_backend_records() won't call the close() function, so
the lock is never released. Thus drop the lock in case of errors here.

gpio updates for v7.1-rc1
GPIO core:
- defer probe on software node lookups when the remote software node
exists but has not been registered as a firmware node yet
- unify GPIO hog handling by moving code duplicated in OF and ACPI
modules into GPIO core and allow setting up hogs with software nodes
- allow matching GPIO controllers by secondary firmware node if matching
by primary does not succeed

using software nodes which don't support fw_devlink yet
- disable the legacy GPIO character device uAPI v1 supprt in Kconfig by
default
- rework several core functions in preparation for the upcoming Revocable
helper library for protecting resources against sudden removal, this
reduces the number of SRCU dereferences in GPIO core
- simplify file descriptor logic in GPIO character device code by using
FD_PREPARE()
- introduce a header defining symbols used by both GPIO consumers and
providers to avoid having to include provider-specific headers from
drivers which only consume GPIOs

Pull gpio updates from Bartosz Golaszewski:
"For this merge window we have two new drivers: support for
GPIO-signalled ACPI events on Intel platforms and a generic
GPIO-over-pinctrl driver using the ARM SCMI protocol for

Several things have been reworked in GPIO core: we unduplicated GPIO
hog handling, reduced the number of SRCU locks and dereferences,
improved support for software-node-based lookup and removed more
legacy code after converting remaining users to modern alternatives.

efi/capsule-loader: fix incorrect sizeof in phys array reallocation
The krealloc() call for cap_info->phys in __efi_capsule_setup_info() uses sizeof(phys_addr_t *) instead of sizeof(phys_addr_t), which might be causing an undersized allocation. The allocation is also inconsistent with the initial array allocation in efi_capsule_open() that allocates one entry with sizeof(phys_addr_t), and the efi_capsule_write() function that stores phys_addr_t values (not pointers) via page_to_phys(). On 64-bit systems where sizeof(phys_addr_t) == sizeof(phys_addr_t *), this goes unnoticed. On 32-bit systems with PAE where phys_addr_t is 64-bit but pointers are 32-bit, this allocates half the required space, which might lead to a heap buffer overflow when storing physical addresses. This is similar to the bug fixed in commit |

efi: Tag memblock reservations of boot services regions as RSRV_KERN
By definition, EFI memory regions of type boot services code or data have no special significance to the firmware at runtime, only to the OS. In some cases, the firmware will allocate tables and other assets that are passed in memory in regions of this type, and leave it up to the OS to decide whether or not to treat the allocation as special, or simply consume the contents at boot and recycle the RAM for ordinary use. The reason for this approach is that it avoids needless memory reservations for assets that the OS knows nothing about, and therefore doesn't know how to free either. This means that any memblock reservations covering such regions can be marked as MEMBLOCK_RSRV_KERN - this is a better match semantically, and is useful on x86 to distinguish true reservations from temporary reservations that are only needed to work around firmware bugs.

efi/memattr: Fix thinko in table size sanity check
While it is true that each PE/COFF runtime driver in memory can generally be split into 3 different regions (the header, the code/rodata region and the data/bss region), each with different permissions, it does not mean that 3x the size of the memory map is a suitable upper bound. This is due to the fact that all runtime drivers could be coalesced into a single EFI runtime code region by the firmware, and if the firmware does a good job of keeping the fragmentation down, it is conceivable that the memory attributes table has more entries than the EFI memory map itself. So instead, base the sanity check on whether the descriptor size matches the EFI memory map's descriptor size closely enough (which is not mandated by the spec but extremely unlikely to differ in practice), and whether the size of the whole table does not exceed 64k entries.

soc fixes for 7.0, part 2
The largest part here are devicetree fixes for Qualcomm, and NXP i.MX, addressing a few regressions and incorrect settings in board and SoC pecific dts files. The largest single commits are a revert of a cleanup patch for i.MX that caused regressions for the NAND flash controller and a fixup for an incomplete cleanup of the PCIe controller on Qualcomm platforms that broke because the state was left incompatible with both the old and new behavior.

Qualcomm driver updates for v7.1
Add ECS LIVA QC710, Glymur CRD, Mahua CRD, Purwa IoT EVK, and Asus Vivobook to the QSEECOM allow-list, to enable UEFI variable access through uefisecapp. Register the Gunyah watchdog device if the SCM driver finds itself running under Gunyah. Clean up some locking using guards. Handle possible cases where AOSS cooling state is given a non-boolean state. Replace LLCC per-slice activation bitmap with reference counting. Also add SDM670 support. Improve probe deferral handling in the OCMEM driver. Add Milos, QCS615, Eliza, Glymur, and Mahua support to the pd-mapper. Add support for SoCCP-based pmic-glink, as found in Glymur and Kaanapali. Add common QMI service ids to the main qmi headerfile, to avoid spreading these constants in various drivers. Add support for version 2 of SMP2P and implement the irqchip state reading support. Add CQ7790, SA8650P, SM7450, SM7450P, and IPQ5210 SoC and the PM7550BA PMIC identifiers to the socinfo driver. Add Eliza and Mahua support to the UBWC driver, introduce helpers for drivers to read out min_acc length and other programmable values, and disable bank swizzling for Glymur. Simplify the logic related to allocation of NV download request in the WCNSS control driver. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmnMQNQACgkQCx85Pw2Z rcWpmA//QDo8m9t4GgAdqJLSyH40Hcw0Uotv4DhzquUe1hYXTQb4NwNoJ+JZVPvO 70BDuJTOQcnQCKeagW1Zq5ycJtA11khRL9ZWwzJB3fq3UTHI+n0EfHDmshAxz37Y h8x71dWKcI3NnEHWBFglRyYbv/eKFxcc2CFP0HrAB3UOxPClqsOVB5iNNM/JA3Jp eppYK6473VAF89q+q7+F3kEhz2p4sgyI9G2Sm/vFqXV3CLY0WV98FjQAHi1nXuNV pCz4oPkccBAcu7FQffMIydbtoIBPZDoI7pueJ4GlgewkkunuiJew/Rq0GEKnyzsN SqzfnBnbfsbQPOtZTBNY6tDgnSMQV2fMtgyBqkmgnSCs6A1AU6XVPFq4wWDpr6t/ +y9QpA/Jfb1txeHp7xY/9bOAl2/vorZDLp9O8CR828z6Ptg/CGO8Gws/X0g4QWvZ 6+UjRHTB5BnJENjzJGoxhrO59gyASUExoM02b6pQmz4ayw9q1PHGMVdSAPCygrDH r9+yMcTO8kfUAYtliJrygDTDlhwxMDfd2z82BOZGpSbAbR8zfFKKJmIaSQGNHCjl u3G9Kb5L7QlAVBGVcRYaArp1MQWD6oP+IU1W9YMra5cySwt/nXtSsQZRdhoP5Qp6 YO8YMdldkf37DNar/+wrN012yaYSWj/k9x/f0phAn106oq1o8+0= =1zur -----END PGP SIGNATURE----- gpgsig -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAmnO3XkACgkQmmx57+YA GNlXDRAAkXYODhxU+T1AyT5OgDBzKgfVBte2vne+NOuirAX6+4U6v+0lCVx+fs4z kTfeveRoXtWlSSF3Vyv+rw1fZvpUOwZ9Y+u405fgveAxtDUkjzJGsnlrfMGIWD4a Q99WFz9L+kTcaf03uNLhrg9UAx0SpkfQQm2riY+ueHVY/0dOTsNzjv71A9sJrmvq oSEH3xquCOgd8diR3evE+2KhD4yQkzMmVeBuujDhWwIJmY8aSpZFIJIXYL5sRo+V l1bd5EwPH2Ku0bXaKh5mLDS/MvdKk7EPKru7ST0+IVfBXBnZf6KefAqljCvVuR66 RRNDN2kcWU+aoih2vuVI+y3w1XGMX9AbFlviaGZWCY1mL2FTFvWfrQ4vLTz2bRlB 8gFPmxMtVZQxu5hBOxAprnYrValRddYamh8cPQcpu9BGIG/ZIqx8cSOXZsQTiARk 9DPRBQsQmaGXXl1YxbcYibQn1TL3ozmqQn0dhZ2Ojkxv0cyD3ymvdv68QKXPf7dm j2LU6BgNiK5IGZ2VUk5mk3hp5Kc+6qpmMqg7l/HIf1zUULCCFWu6l/IobuaX7ynj b5EU0feXMCJ9B17G1lgdFsZ0oI3RhkROjCi2huklNh1fA/xThwTsZsZQ9NmEKQHw TDCcavPXh64fSVtv4qePd9HV+KcHeBeA18m+6njdqByT36qMeC0= =nCjL -----END PGP SIGNATURE----- Merge tag 'qcom-drivers-for-7.1' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers Qualcomm driver updates for v7.1 Add ECS LIVA QC710, Glymur CRD, Mahua CRD, Purwa IoT EVK, and Asus Vivobook to the QSEECOM allow-list, to enable UEFI variable access through uefisecapp. Register the Gunyah watchdog device if the SCM driver finds itself running under Gunyah.
