Subject: lib: delete lib/find_last_bit.c
has been removed from the -mm tree. Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Yury Norov <yury.norov@xxxxxxxxx>
Subject: lib: delete lib/find_last_bit.c
File find_next_bit.c was deleted in patch "lib: move find_last_bit to
lib/find_next_bit.c" from Feb, 22, but not in master (commit 8f6f19dd51).
This is just a fix for wrong merge.
