Subject: Documentation: kdump: clean up the outdated description
Date: Fri, 29 Mar 2024 21:28:25 +0800
After commit 443cbaf9e2fd ("crash: split vmcoreinfo exporting code out
from crash_core.c"), Kconfig item CRASH_CORE has gone away in kernel.
Items VMCORE_INFO and CRASH_RESERVE are used instead.
So clean up the outdated description about CRASH_CORE and update it
accordingly.
