[ARM] 3252/1: help gcc do the best with ___arch__swab32 Patch from Nicolas Pitre Depending on your gcc version, the current C-only implementation would produce suboptimal code, ranging from a bad register selection forcing an additional mov instruction to a failure to merge the eor and the ror in a single instruction. With a little help gcc always produces the best code. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
