find_first_*_bit() is simpler and faster than 'next' version [1], and they work identically if start == 0. But in many cases kernel code uses the 'next' version where 'first' can be used. This series addresses this issue. Patches 1-3 move find.h under include/linux as it simplifies development. Patches 4-8 switch the kernel and tools to find_first_*_bit() implementation where appropriate.
