The quilt patch titled
     Subject: reboot: retire hw_protection_reboot and hw_protection_shutdown helpers
has been removed from the -mm tree.  Its filename was
     reboot-retire-hw_protection_reboot-and-hw_protection_shutdown-helpers.patch

This patch was dropped because it was merged into the mm-nonmm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: reboot: retire hw_protection_reboot and hw_protection_shutdown helpers
Date: Mon, 17 Feb 2025 21:39:52 +0100

The hw_protection_reboot and hw_protection_shutdown functions mix
mechanism with policy: They let the driver requesting an emergency action
for hardware protection also decide how to deal with it.

This is inadequate in the general case as a driver reporting e.g.  an
imminent power failure can't know whether a shutdown or a reboot would be
more appropriate for a given hardware platform.

With the addition of the hw_protection parameter, it's now possible to
configure at runtime the default emergency action and drivers are expected
to use hw_protection_trigger to have this parameter dictate policy.

As no current users of either hw_protection_shutdown or
hw_protection_shutdown helpers remain, remove them, as not to tempt driver
authors to call them.

Existing users now either defer to hw_protection_trigger or call
__hw_protection_trigger with a suitable argument directly when they have
inside knowledge on whether a reboot or shutdown would be more
appropriate.
