The quilt patch titled
     Subject: m68k, kexec: fix the incorrect ifdeffery and build dependency of CONFIG_KEXEC
has been removed from the -mm tree.  Its filename was

Subject: m68k, kexec: fix the incorrect ifdeffery and build dependency of CONFIG_KEXEC
Date: Fri, 8 Dec 2023 15:30:33 +0800

The select of KEXEC for CRASH_DUMP in kernel/Kconfig.kexec will be
dropped, then compiling errors will be triggered if below config items are
set:

===
CONFIG_CRASH_CORE=y
CONFIG_KEXEC_CORE=y
CONFIG_CRASH_DUMP=y
===

Here, change the dependency of buinding machine_kexec.o relocate_kernel.o
and the ifdeffery in asm/kexe.h to CONFIG_KEXEC_CORE.
