locking/atomic, s390: Use s64 for atomic64
As a step towards making the atomic64 API use consistent types treewide,
let's have the s390 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.
The s390-internal __atomic64_*() ops are also used by the s390 bitops,
and expect pointers to long. Since atomic64_t::counter will be converted
to s64 in a subsequent patch, pointes to this are explicitly cast to
pointers to long when passed to __atomic64_*() ops.
Otherwise, there should be no functional change as a result of this
patch.
