Subject: [RFC PATCH 4/4] riscv: cmpxchg: Remove unused cmpxchg(64)_local
Date: Mon,  8 Aug 2022 04:06:00 -0400	[thread overview]
Message-ID: <20220808080600.3346843-5-guoren@kernel.org> (raw)
In-Reply-To: <20220808080600.3346843-1-guoren@kernel.org>

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

Only cmpxchg64_local is used in drivers/iommu/intel/iommu.c, and
cmpxchg_local has been deprecated in common part. So cmpxchg_local
is unecessary to riscv.
