Subject: arch/loongarch: clean up the left code and Kconfig item related to CRASH_CORE
Date: Fri, 29 Mar 2024 21:28:24 +0800

Patch series "crash: clean up outdated codes and doc related to
CRASH_CORE".

As Geert pointed out that there are still left codes and doc related to
CRASH_CORE in arch/loongarch and Documentation.  So make these two patches
to clean them up.  Thanks to Geert.


This patch (of 2):

In commit 85fcde402db1 ("kexec: split crashkernel reservation code out
from crash_core.c"), crashkernel reservation code is split out from
crash_core.c, and add CRASH_RESERVE to control it.  And also rename each
ARCH's <asm/crash_core.h> to <asm/crash_reserve.h> accordingly.

But the relevant part in loongarch is missed. Do it now.
