Subject: [PATCH v10 1/8] crash: introduce arch/*/asm/crash.h
Date: Thu, 21 Jul 2022 14:17:40 -0400 [thread overview]
Message-ID: <20220721181747.1640-2-eric.devolder@oracle.com> (raw)
In-Reply-To: <20220721181747.1640-1-eric.devolder@oracle.com>
The use of __weak is being eliminated within kexec sources.
The technique uses macros mapped onto inline functions in
order to replace __weak.
This patchset was using __weak and so in order to replace
__weak, this patch introduces arch/*/asm/crash.h, patterned
after how kexec is moving away from __weak and to the macro
definitions.
No functionality changed, yet.
