Merge tag 'amd_ucode_fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/bp/bp into x86/urgent
Pull AMD microcode fixes from Borislav Petkov: " Those are basically two fixes which correct the AMD early ucode loader from accessing cpu_data too early, i.e. before smp_store_cpu_info() has copied the boot_cpu_data ontop and overwritten an already empty structure (which we shouldn't access that early in the first place anyway). The second patch is kinda largish for that late in the game but it shouldn't be problematic because we're simply switching from using cpu_data to use the CPU family number directly and thus again, not use uninitialized cpu_data structure. " Signed-off-by: Ingo Molnar <mingo@kernel.org>
