However, if the vma of the accessing vaddr is VM_PFNMAP, walk_page_range() will skip the vma in walk_page_test() and return 0. Before commit aaf99ac2ceb7 ("mm/hwpoison: do not send SIGBUS to processes with recovered clean pages"), kill_accessing_process() will return EFAULT. For x86, the current task will be killed in kill_me_maybe(). However, after this commit, kill_accessing_process() simplies return 0, that means UCE is handled properly, but it doesn't actually. In such case, the user task will trigger UCE infinitely. To fix it, add .test_walk callback for hwpoison_walk_ops to scan all vmas.

As long as "sym" doesn't contain any odd characters, no quoting is required for its use with .quad / .long. In fact the quotation gets in the way with gas 2.25; it's only from 2.26 onwards that quoted symbols are half-way properly supported. However, assembly being different from C anyway, drop __ADDRESSABLE_ASM_STR() and its helper macro altogether. A simple .global directive will suffice to get the symbol "declared", i.e. into the symbol table. While there also stop open-coding STATIC_CALL_TRAMP() and STATIC_CALL_KEY().

This allows the driver to be safely used with DMA-enabled SPI controllers. The buffer array is also converted to a struct with a union to make the usage of the memory in the buffer more clear and ensure proper alignment.

FAILED: patch "[PATCH] iio: imu: inv_icm42600: change invalid data error to -EBUSY" failed to apply to 6.16-stable tree

by gregkh＠linuxfoundation.org

The patch below does not apply to the 6.16-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>.

If both accel and gyro are off, the temperature sensor is also automatically turned off and returns invalid data. In this case, returning -EBUSY error code is better then -EINVAL and indicates userspace that it needs to retry reading temperature in another context.

PPC GPU hangs patch

by Mario Limonciello

Hi, Some GPU hangs are reported on PowerPC with some dGPUs. This patch is reported [1] to improve them: commit 0ef2803173f1 ("drm/amdgpu/vcn1: read back register after written") The other VCN versions are already in 6.15.9, this one didn't come back though AFAICT. Can you take it back to remaining stable trees? [1] https://gitlab.freedesktop.org/drm/amd/-/issues/3787 Thanks,
