Subject: [PATCH v6 05/14] arm64/kexec: refactor for kernel/Kconfig.kexec
Date: Wed, 12 Jul 2023 12:15:36 -0400 [thread overview]
Message-ID: <20230712161545.87870-6-eric.devolder@oracle.com> (raw)
In-Reply-To: <20230712161545.87870-1-eric.devolder@oracle.com>
The kexec and crash kernel options are provided in the common
kernel/Kconfig.kexec. Utilize the common options and provide
the ARCH_SUPPORTS_ and ARCH_SELECTS_ entries to recreate the
equivalent set of KEXEC and CRASH options.
