Subject: [PATCH 3/3] s390/Kconfig: drop select of KEXEC
Date: Thu, 23 Nov 2023 15:36:52 +0800	[thread overview]
Message-ID: <20231123073652.507034-4-bhe@redhat.com> (raw)
In-Reply-To: <20231123073652.507034-1-bhe@redhat.com>

No proof is found to require that S390 architecture has to select
KEXEC. At least from my testing at below, dropping select of KEXEC won't
impact anything.

===testing 1===
CONFIG_CRASH_CORE=y
CONFIG_KEXEC_CORE=y
CONFIG_CRASH_DUMP=y
===

===testing 2===
CONFIG_CRASH_CORE=y
CONFIG_KEXEC_CORE=y
CONFIG_KEXEC_FILE=y
CONFIG_CRASH_DUMP=y
===

So drop the select of KEXEC now.
