Subject: [RFC PATCH v2 11/31] kvx: Add atomic/locking headers
Date: Fri, 20 Jan 2023 15:09:42 +0100 [thread overview]
Message-ID: <20230120141002.2442-12-ysionneau@kalray.eu> (raw)
In-Reply-To: <20230120141002.2442-1-ysionneau@kalray.eu>
Add common headers (atomic, bitops, barrier and locking) for basic
kvx support.

Notes:
V1 -> V2:
- use {READ,WRITE}_ONCE for arch_atomic64_{read,set}
- use asm-generic/bitops/atomic.h instead of __test_and_*_bit
- removed duplicated includes
- rewrite xchg and cmpxchg in C using builtins for acswap insn
