The swab() is massively over complicated
Simplify it with compiler builtins and fallback to plain C function
if undefined.
Update components to switch to this new swap bytes.
Lin Liu (7):
xen: implement byteswap.h
crypto/vmac: Simplify code with byteswap.h
arm64/find_next_bit: Remove ext2_swab()
arm: Switch to byteswap.h
xen/xsm: Switch to byteswap.h
