Its filename is m68k-kexec-refactor-for-kernel-kconfigkexec.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/m68k-kexec-refactor-for-kernel-kconfigkexec.patch This patch will later appear in the mm-nonmm-unstable branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next via the mm-everything branch at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm and is updated there every 2-3 working days ------------------------------------------------------ From: Eric DeVolder Subject: m68k/kexec: refactor for kernel/Kconfig.kexec Date: Thu, 6 Jul 2023 18:20:21 -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.
