The LEDs are driven by the GPIO{15,16} pins of the North Bridge GPIO controller. These pins are part of the 'spi_quad' pin group for which the 'spi' function is selected via the default pinctrl state of the 'spi' node. This is wrong however, since in order to allow controlling the LEDs, the pins should use the 'gpio' function. Before the commit mentined above, the 'spi' function is selected first by the pinctrl core before probing the spi driver, but then it gets overridden to 'gpio' implicitly via the devm_gpiod_get_index_optional() call from the 'leds-gpio' driver. After the commit, the LED subsystem gets initialized before the SPI subsystem, so the function of the pin group remains 'spi' which in turn prevents controlling of the LEDs. Despite the change of the initialization order, the root cause is that the pinctrl state definition is wrong since its initial commit 0d45062cfc89 ("arm64: dts: marvell: Add device tree for uDPU board"), To fix the problem, override the function in the 'spi_quad_pins' node to 'gpio' and move the pinctrl state definition from the 'spi' node into the 'leds' node.

[PATCH] ACPI/IORT: Fix memory leak in iort_rmr_alloc_sids()

by Miaoqian Lin

If krealloc_array() fails in iort_rmr_alloc_sids(), the function returns NULL but does not free the original 'sids' allocation. This results in a memory leak since the caller overwrites the original pointer with the NULL return value.

[PATCH v6.16.y] drm/dp: Change AUX DPCD probe address to DP_TRAINING_PATTERN_SET

by Imre Deak

commit d34d6feaf4a76833effcec0b148b65946b04cde8 upstream. Change the AUX DPCD probe address to DP_TRAINING_PATTERN_SET. Using DP_DPCD_REV for this is not compliant with the DP Standard and it leads to link training failures at least on a DP2.0 docking station when using UHBR link rates. This patch is a revert of commit 944e732be9c3 ("drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS") and the corresponding fix for commit 05981233cf2e ("Revert "drm/dp: Change AUX DPCD probe address from DPCD_REV to LANE0_1_STATUS") in the v6.16.y tree.

[GIT PULL 6.18 1/2] xfs: improve online repair reap calculations

by Darrick J. Wong

Hi Carlos, Please pull this branch with changes for xfs. As usual, I did a test-merge with the main upstream branch as of a few minutes ago, and didn't see any conflicts. Please let me know if you encounter any problems. --D The following changes since commit b320789d6883cc00ac78ce83bccbfe7ed58afcf0: Linux 6.17-rc4 (2025-08-31 15:33:07 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/djwong/xfs-linux.git tags/fix-scrub-reap-calculations_2025-09-05 for you to fetch changes up to 07c34f8cef69cb8eeef69c18d6cf0c04fbee3cb3: xfs: use deferred reaping for data device cow extents (2025-09-05 08:48:23 -0700) ---------------------------------------------------------------- xfs: improve online repair reap calculations [6.18 v2 1/2] A few months ago, the multi-fsblock untorn writes patchset added a bunch of log intent item helper functions to estimate the number of intent items that could be added to a particular transaction. Those helpers enabled us to compute a safe upper bound on the number of blocks that could be written in an untorn fashion with filesystem-provided out of place writes. Currently, the online fsck code employs static limits on the number of intent items that it's willing to accrue to a single transaction when it's trying to reap what it thinks are the old blocks from a corrupt structure. There have been no problems reported with this approach after years of testing, but static limits are scary and gross because overestimating the intent item limit could result in transaction overflows and dead filesystems; and underestimating causes unnecessary overhead. This series uses the new log intent item size helpers to estimate the limits dynamically based on worst-case per-block repair work vs. the size of the scrub transaction. After several months of testing this, there don't seem to be any problems here either. v2: rearrange patches, add review tags This has been running on the djcloud for months with no problems. Enjoy!

[PATCHSET 6.18 v2 1/2] xfs: improve online repair reap calculations

by Darrick J. Wong

Hi all, A few months ago, the multi-fsblock untorn writes patchset added a bunch of log intent item helper functions to estimate the number of intent items that could be added to a particular transaction. Those helpers enabled us to compute a safe upper bound on the number of blocks that could be written in an untorn fashion with filesystem-provided out of place writes. Currently, the online fsck code employs static limits on the number of intent items that it's willing to accrue to a single transaction when it's trying to reap what it thinks are the old blocks from a corrupt structure. There have been no problems reported with this approach after years of testing, but static limits are scary and gross because overestimating the intent item limit could result in transaction overflows and dead filesystems; and underestimating causes unnecessary overhead. This series uses the new log intent item size helpers to estimate the limits dynamically based on worst-case per-block repair work vs. the size of the scrub transaction. After several months of testing this, there don't seem to be any problems here either. v2: rearrange patches, add review tags If you're going to start using this code, I strongly recommend pulling from my git trees, which are linked below. This has been running on the djcloud for months with no problems. Enjoy! Comments and questions are, as always, welcome. --D kernel git tree: https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git/log/?h=fi… --- Commits in this patchset: * xfs: use deferred intent items for reaping crosslinked blocks * xfs: prepare reaping code for dynamic limits * xfs: convert the ifork reap code to use xreap_state * xfs: compute per-AG extent reap limits dynamically * xfs: compute data device CoW staging extent reap limits dynamically * xfs: compute realtime device CoW staging extent reap limits dynamically * xfs: compute file mapping reap limits dynamically * xfs: remove static reap limits from repair.h * xfs: use deferred reaping for data device cow extents --- fs/xfs/scrub/repair.h | 8 - fs/xfs/scrub/trace.h | 45 ++++ fs/xfs/scrub/newbt.c | 9 + fs/xfs/scrub/reap.c | 622 +++++++++++++++++++++++++++++++++++++++---------- fs/xfs/scrub/trace.c | 1 5 files changed, 554 insertions(+), 131 deletions(-)

[PATCH] x86/boot/compressed/64: clear high flags from pgd entry in configure_5level_paging

by Eric Hagberg

In commit d0ceea662d45 ("x86/mm: Add _PAGE_NOPTISHADOW bit to avoid updating userspace page tables") we started setting _PAGE_NOPTISHADOW (bit 58) in identity map PTEs created by kernel_ident_mapping_init. In configure_5level_paging when transiting from 5-level paging to 4-level paging we copy the first p4d to become our new (4-level) pgd by dereferencing the first entry in the current pgd, but we only mask off the low 12 bits in the pgd entry. When kexecing, the previous kernel sets up an identity map using kernel_ident_mapping_init before transiting to the new kernel, which means the new kernel gets a pgd with entries with bit 58 set. Then we mask off only the low 12 bits, resulting in a non-canonical address, and try to copy from it, and fault.
