Subject: [RFC PATCH 0/4] riscv: Add basic percpu operations
Date: Mon, 8 Aug 2022 04:05:56 -0400 [thread overview]
Message-ID: <20220808080600.3346843-1-guoren@kernel.org> (raw)
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
