Subject: [PATCH 1/6] sh: Move cmpxchg-xchg.h to asm-generic
Date: Mon, 14 Oct 2019 00:13:05 +0200	[thread overview]
Message-ID: <20191013221310.30748-2-sebastian@breakpoint.cc> (raw)
In-Reply-To: <20191013221310.30748-1-sebastian@breakpoint.cc>

The header file is very generic and could be reused by other
architectures as long as they provide __cmpxchg_u32().

Move sh's cmpxchg-xchg.h to asm-generic.
