Subject: [PATCH 03/33] locking/atomic: h8300: use asm-generic exclusively
Date: Mon, 10 May 2021 10:37:23 +0100 [thread overview]
Message-ID: <20210510093753.40683-4-mark.rutland@arm.com> (raw)
In-Reply-To: <20210510093753.40683-1-mark.rutland@arm.com>
As h8300's implementation of the atomics isn't using any arch-specific
functionality, and its implementation of cmpxchg only uses assembly to
non-atomically swap two elements in memory, we may as well use the
asm-generic atomic.h and cmpxchg.h, and avoid the duplicate code.
