The patch titled
     asm-generic/atomic.h: fix type used in atomic_clear_mask
has been removed from the -mm tree.  Its filename was
     asm-generic-atomich-fix-type-used-in-atomic_clear_mask.patch

This patch was dropped because it was merged into mainline or a subsystem tree

The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: asm-generic/atomic.h: fix type used in atomic_clear_mask
From: Mike Frysinger <vapier@gentoo.org>

The atomic helpers are supposed to take an atomic_t pointer, not a random
unsigned long pointer.  So convert atomic_clear_mask over.

While we're here, also add some nice documentation to the func.
