Subject: crash_core: change the prototype of function parse_crashkernel()
has been removed from the -mm tree. Its filename was
crash_core-change-the-prototype-of-function-parse_crashkernel.patch

Subject: crash_core: change the prototype of function parse_crashkernel()
Date: Thu, 14 Sep 2023 11:31:35 +0800
Add two parameters 'low_size' and 'high' to function parse_crashkernel(),
later crashkernel=,high|low parsing will be added. Make adjustments in
all call sites of parse_crashkernel() in arch.
