The patch titled
x86: bitops take an unsigned long *
has been removed from the -mm tree. Its filename was
x86-bitops-take-an-unsigned-long.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: x86: bitops take an unsigned long *
From: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx>
All (or most) other architectures do this. So should x86. Fix.
