The patch titled
Subject: lib: bitmap: make nbits parameter of bitmap_complement unsigned
has been removed from the -mm tree. Its filename was
lib-bitmap-make-nbits-parameter-of-bitmap_complement-unsigned.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: lib: bitmap: make nbits parameter of bitmap_complement unsigned
The compiler can generate slightly smaller and simpler code when it knows
that "nbits" is non-negative. Since no-one passes a negative bit-count,
this shouldn't affect the semantics.
