Merge branch 'for-6.15/amd_sfh' into for-linus

From: Mario Limonciello <mario.limonciello@amd.com>

Some platforms include a human presence detection (HPD) sensor. When
enabled and a user is detected a wake event will be emitted from the
sensor fusion hub that software can react to.

Example use cases are "wake from suspend on approach" or to "lock
when leaving".

This is currently enabled by default on supported systems, but users
can't control it. This essentially means that wake on approach is
enabled which is a really surprising behavior to users that don't
expect it.

Instead of defaulting to enabled add a sysfs knob that users can
use to enable the feature if desirable and set it to disabled by
default.

Pull sysctl table constification from Joel Granados:
"All ctl_table declared outside of functions and that remain unmodified
after initialization are const qualified.

This prevents unintended modifications to proc_handler function
pointers by placing them in the .rodata section.

This is a continuation of the tree-wide effort started a few releases

sysctl API done in 78eb4ea25cd5 ("sysctl: treewide: constify the
ctl_table argument of proc_handlers")"

treewide: const qualify ctl_tables where applicable

Add the const qualifier to all the ctl_tables in the tree except for
watchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,
loadpin_sysctl_table and the ones calling register_net_sysctl (./net,
drivers/inifiniband dirs). These are special cases as they use a
registration function with a non-const qualified ctl_table argument or
modify the arrays before passing them on to the registration function.

Constifying ctl_table structs will prevent the modification of
proc_handler function pointers as the arrays would reside in .rodata.
This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide:
constify the ctl_table argument of proc_handlers") constified all the
proc_handlers.

Created this by running an spatch followed by a sed command:

* Code formatting was adjusted in xfs_sysctl.c to comply with code
conventions. The xfs_stats_clear_proc_handler,
xfs_panic_mask_proc_handler and xfs_deprecated_dointvec_minmax where
adjusted.

* The ctl_table argument in proc_watchdog_common was const qualified.
This is called from a proc_handler itself and is calling back into
another proc_handler, making it necessary to change it as part of the
proc_handler migration.

Merge tag 'sysctl-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl

Pull sysctl updates from Joel Granados:

- Remove "->procname == NULL" check when iterating through sysctl table
arrays

Removing sentinels in ctl_table arrays reduces the build time size
and runtime memory consumed by ~64 bytes per array. With all
ctl_table sentinels gone, the additional check for ->procname == NULL
that worked in tandem with the ARRAY_SIZE to calculate the size of
the ctl_table arrays is no longer needed and has been removed. The
sysctl register functions now returns an error if a sentinel is used.

- Preparation patches for sysctl constification

Constifying ctl_table structs prevents the modification of
proc_handler function pointers as they would reside in .rodata. The
ctl_table arguments in sysctl utility functions are const qualified
in preparation for a future treewide proc_handler argument
constification commit.

- Misc fixes

Increase robustness of set_ownership by providing sane default
ownership values in case the callee doesn't set them. Bound check
proc_dou8vec_minmax to avoid loading buggy modules and give sysctl
testing module a name to avoid compiler complaints.
