Merge branch 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
* 'x86-microcode-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86, microcode, AMD: Add microcode revision to /proc/cpuinfo x86, microcode: Correct microcode revision format coretemp: Get microcode revision from cpu_data x86, intel: Use c->microcode for Atom errata check x86, intel: Output microcode revision in /proc/cpuinfo x86, microcode: Don't request microcode from userspace unnecessarily Fix up trivial conflicts in arch/x86/kernel/cpu/amd.c (conflict between moving AMD BSP code to cpu_dev helper function and adding AMD microcode revision to /proc/cpuinfo code)
