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)
