[PATCH 0/4] Some minor printf improvements

From: Rasmus Villemoes
Date: Fri Feb 20 2015 - 18:21:53 EST

While studying the kernel's printf internals in order to write the
kernel-specific format checking for smatch, I stumbled on a few things
one could do to shave an instruction here and there. Nothing

Rasmus Villemoes (4):
lib/vsprintf.c: Eliminate some branches
lib/vsprintf.c: Reduce stack use in number()
lib/vsprintf.c: Eliminate duplicate hex string array
lib/vsprintf.c: Another small hack
