Subject: ppc, crash: enforce KEXEC and KEXEC_FILE to select CRASH_DUMP
Date: Wed, 24 Jan 2024 13:12:48 +0800
In PowerPC, the crash dumping and kexec reboot share code in
arch_kexec_locate_mem_hole(), in which struct crash_mem is used.
Here enfoce enforce KEXEC and KEXEC_FILE to select CRASH_DUMP for now.
