Subject: [PATCH v2 08/14] ppc, crash: enforce KEXEC and KEXEC_FILE to select CRASH_DUMP
Date: Fri, 19 Jan 2024 22:52:35 +0800 [thread overview]
Message-ID: <20240119145241.769622-9-bhe@redhat.com> (raw)
In-Reply-To: <20240119145241.769622-1-bhe@redhat.com>
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.
