The patch titled
alpha: fix bitops
has been removed from the -mm tree. Its filename was
alpha-fix-bitops.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: alpha: fix bitops
From: Nick Piggin <npiggin@xxxxxxx>
Documentation/atomic_ops.txt defines these primitives must contain a memory
barrier both before and after their memory operation. This is consistent with
the atomic ops implementation on alpha.
