Merge branch 'drop-time' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild
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
