Subject: [PATCH V4 1/5] riscv: atomic: Cleanup unnecessary definition
Date: Thu,  5 May 2022 11:55:22 +0800	[thread overview]
Message-ID: <20220505035526.2974382-2-guoren@kernel.org> (raw)
In-Reply-To: <20220505035526.2974382-1-guoren@kernel.org>

From: Guo Ren <guoren@linux.alibaba.com>

The cmpxchg32 & cmpxchg32_local are not used in Linux anymore. So
clean up asm/cmpxchg.h.
