Pull gpio updates from Bartosz Golaszewski:
 "GPIO core:
   - extend the gpio-regmap abstraction layer with more features
     allowing users to override configuration setting, translate
     register values and masks and enable/disable interrupts
   - extend GPIO kunit tests with suites verifying probe ordering by
     software node devlink support and software node hogs
   - shrink GPIO kunit initialization code
   - coding style updates (remove commas from sentinels where
     applicable)
   - with all users now converted treewide to using real firmware node
     links for software node GPIO lookup: remove the deprecated
     label-matching mechanism from from GPIO core
   - drop redundant return value check of nonseekable_open() in
     gpiolib-cdev
   - use IRQ trigger helpers where applicable

  Driver updates:
   - refactor error paths and logging in gpio-nomadik
   - use more modern interfaces for getting resources in gpio-rockchip,
     gpio-bt8xx and gpio-pca9570
   - add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610
   - drop unused FILONOFF macro from gpio-rcar
   - extend build coverage of ioport GPIO drivers with COMPILE_TEST=y
   - only enable the gpio-rtd driver by default with ARCH_REALTEK=y to
     avoid bloating the build
   - refactor coding style in several drivers
   - use correct endianess translation in gpio-pcf85x
   - add wake-up interrupt support to gpio-mvebu
   - apply initial value in direction output setter in gpio-by-pinctrl

  Misc:
   - replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h
     which now exports all the deprecated APIs
   - select GPIOLIB_LEGACY in Kconfig where required treewide
   - use software nodes for gpio-keys in MFD drivers

  Devicetree bindings:
   - describe the realtek rtd1625 GPIO controller
   - document new models for gpio-pca95xx and gpio-cadence
   - document new property in gpio-rockchip"

2026-07-24T18:12:48+00:00

linux/gpio.h should no longer be used, convert these instead to
linux/gpio/legacy.h for the sh boards using the legacy interfaces,
or remove it where it is not needed at all.

This has been scheduled for removal more than a decade ago and the comments
related to it have been dutifully ignored. The last dependencies are gone.

Remove it along with various now empty asm/timex.h files.

uaccess: unify inline vs outline copy_{from,to}_user() selection

2026-05-29T04:24:44+00:00

The kernel allows arches to select between inline and outline
implementations of the copy_{from,to}_user() by defining individual
INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER, correspondingly.  However,
all arches enable or disable them always together.

Without the real use-case for one helper being inlined while the other
outlined, having independent controls is excessive and error prone.

Switch the codebase to the single unified INLINE_COPY_USER control.

ring-buffer: Flush and stop persistent ring buffer on panic

2026-05-21T12:20:58+00:00

On real hardware, panic and machine reboot may not flush hardware cache
to memory. This means the persistent ring buffer, which relies on a
coherent state of memory, may not have its events written to the buffer
and they may be lost. Moreover, there may be inconsistency with the
counters which are used for validation of the integrity of the
persistent ring buffer which may cause all data to be discarded.

To avoid this issue, stop recording of the ring buffer on panic and
flush the cache of the ring buffer's memory.

sh: Fix fallout from ZERO_PAGE consolidation

2026-05-03T14:35:40+00:00

Consolidation of empty_zero_page declarations broke boot on sh.

sh stores its initial boot parameters in a page reserved in
arch/sh/kernel/head_32.S. Before commit 6215d9f4470f ("arch, mm:
consolidate empty_zero_page") this page was referenced in C code
as an array and after that commit it is referenced as a pointer.

This causes wrong code generation and boot hang.

Declare boot_params_page as an array to fix the issue.

Merge tag 'sh-for-v7.1-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux

2026-04-20T23:41:19+00:00

Pull sh updates from John Paul Adrian Glaubitz:
 "Two patches from Thomas Zimmermann, one by Tim Bird and one by Thomas
  Weißschuh.

  The first patch by Thomas Zimmermann adds a missing include in dac.h
  for SH-3 which became necessary after 243ce64b2b37 ("backlight: Do not
  include  in header file") which made __raw_readb() and
  __raw_writeb() inaccessible in dac.h.

  Thomas' second patch drops CONFIG_FIRMWARE_EDID for SH as it depends
  on X86 or EFI_GENERIC_STUB which are not defined on SH for obvious
  reasons.

  The patch by Tim Bird fixes just a small typo in two SPDX ID lines
  which he stumbled over by accident.

  And, least but not last, the patch by Thomas Weißschuh removes the
  CONFIG_VSYSCALL reference from UAPI. This was necessary as the
  definition of AT_SYSINFO_EHDR was gated between CONFIG_VSYSCALL to
  avoid a default gate VMA to be created. However that default gate VMA
  was removed entirely in commit a6c19dfe3994 (arm64,ia64,ppc,s390,
  sh,tile,um,x86,mm: remove default gate area)"

sh: Remove CONFIG_VSYSCALL reference from UAPI

2026-04-18T08:23:15+00:00

AT_SYSINFO_EHDR defines the auxvector index representing the vDSO
entrypoint. Its value or presence does not depend on whether a vDSO
is actually provided by the kernel.

The definition of AT_SYSINFO_EHDR was gated between CONFIG_VSYSCALL to
avoid a default gate VMA to be created. However that default gate VMA
was removed entirely in commit a6c19dfe3994
("arm64,ia64,ppc,s390,sh,tile,um,x86,mm: remove default gate area").

Remove the now unnecessary conditional.
