The patch titled
Subject: lib/bitmap.c: make the bits parameter of bitmap_remap unsigned
has been removed from the -mm tree. Its filename was
lib-bitmap-make-the-bits-parameter-of-bitmap_remap-unsigned.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Rasmus Villemoes <linux@xxxxxxxxxxxxxxxxxx>
Subject: lib/bitmap.c: make the bits parameter of bitmap_remap unsigned
Also, rename bits to nbits. Both changes for consistency with other
bitmap_* functions.
