[RFC PATCH 4/4] riscv: cmpxchg: Remove unused cmpxchg(64)_local

From: guoren
Date: Mon Aug 08 2022 - 04:07:11 EST


From: Guo Ren <guoren@xxxxxxxxxxxxxxxxx>

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.
