find_fisrt_{zero_}bit are too heavy for bitmap_{full,empty}. We don't
need to calculate and compare the position of bitmap. This set of patch
instroduces lightweight api and replaces the heavy one.
Jia He (3):
linux/bitmap: Move 2 mask macro from bitmap.h to bitops.h
lib: Introduce 2 find bit api: all_is_bit_{one,zero}
linux/bitmap: Replace find_fisrt_{zero_}bit with the new lightweight api
