The quilt patch titled

has been removed from the -mm tree.  Its filename was
     sh-kexec-refactor-for-kernel-kconfigkexec.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: sh/kexec: refactor for kernel/Kconfig.kexec
Date: Wed, 12 Jul 2023 12:15:44 -0400

The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.

-	  kexec is a system call that implements the ability to shutdown your

-	  but it is independent of the system firmware.  And like a reboot
-	  you can start any kernel with it, not just Linux.
