Subject: [PATCH linux-next v3 10/14] sh, crash: wrap crash dumping code into crash related ifdefs
Date: Wed, 24 Jan 2024 13:12:50 +0800

Now crash codes under kernel/ folder has been split out from kexec
code, crash dumping can be separated from kexec reboot in config
items on SuperH with some adjustments.

wrap up crash dumping codes with CONFIG_CRASH_DUMP ifdeffery, and
use IS_ENABLED(CONFIG_CRASH_RESERVE) check to decide if compiling
in the crashkernel reservation code.
