Pull __TIME__/__DATE__ removal from Michal Marek:
 "This series by Josh finishes the removal of __DATE__ and __TIME__ from
  the kernel.  The last patch adds -Werror=date-time to KBUILD_CFLAGS to
  stop these from reappearing.

  Part of the series went through Greg's trees during this merge window,
  which is why this pull request is not based on v3.13-rc1"

* 'drop-time' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
  Makefile: Build with -Werror=date-time if the compiler supports it
  x86: math-emu: Drop already-disabled print of build date
  net: wireless: brcm80211: Drop debug version with build date/time
  mtd: denali: Drop print of build date/time
