Subject: [PATCH v5 06/10] arm64: lse: Remove unused 'alt_lse' assembly macro
Date: Thu, 29 Aug 2019 16:48:30 +0100 [thread overview]
Message-ID: <20190829154834.26547-7-will@kernel.org> (raw)
In-Reply-To: <20190829154834.26547-1-will@kernel.org>
The 'alt_lse' assembly macro has been unused since 7c8fc35dfc32
("locking/atomics/arm64: Replace our atomic/lock bitop implementations
with asm-generic").
Remove it.
