2021-04-18	simplify AND(x >= 0, x < C) --> (unsigned)x < C	Luc Van Oostenryck	1	-1/+0
	Such compares with a signed value are relatively common and can be easily be simplified into a single unsigned compare. So, do it. Note: This simplification triggers only 27 times in a x86-64 defconfig kernel. I expected more but I suppose it's because most checks aren't done against a constant or are done with unsigned values.
