From: Guo Ren <guoren@linux.alibaba.com>
The series try to add basic percpu operations for riscv. HAVE_CMPXCHG_LOCAL would let people confuse with cmpxchg(64)_local, so make the name more accurate (HAVE_CMPXCHG_PERCPU_BYTE). Last, remove RISC-V's cmpxchg(64)_local definition because it's no use.
Guo Ren (4): vmstat: percpu: Rename HAVE_CMPXCHG_LOCAL to HAVE_CMPXCHG_PERCPU_BYTE arm64: percpu: Use generic PERCPU_RW_OPS riscv: percpu: Implement this_cpu operations riscv: cmpxchg: Remove unused cmpxchg(64)_local
