Subject: [PATCH 0/4] Some minor printf improvements

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
earth-shattering.

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
