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 ------------------------------------------------------ From: Eric DeVolder 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.
