Subject: [PATCH 14/18] locking/atomic: sparc: use s64 for atomic64
Date: Wed, 22 May 2019 14:22:46 +0100
Message-ID: <20190522132250.26499-15-mark.rutland@arm.com> (raw)
In-Reply-To: <20190522132250.26499-1-mark.rutland@arm.com>

As a step towards making the atomic64 API use consistent types treewide,
let's have the sparc atomic64 implementation use s64 as the underlying
type for atomic64_t, rather than long, matching the generated headers.

As atomic64_read() depends on the generic defintion of atomic64_t, this
still returns long. This will be converted in a subsequent patch.

Otherwise, there should be no functional change as a result of this patch.
