[PATCH] mm: fill arch atomic64 gaps
alpha, sparc64, x86_64 are each missing some primitives from their atomic64 support: fill in the gaps I've noticed by extrapolating asm, follow the groupings in each file. But powerpc and parisc still lack atomic64. Signed-off-by: Hugh Dickins <hugh@veritas.com> Cc: Richard Henderson <rth@twiddle.net> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: "David S.
