I've also fixed the format of the new X86_BUG_OLD_MICROCODE entry to
the canonical format used in <asm/cpufeatures.h> (see the delta patch
below), and pre-merged tip:x86/cpu with fixes/changes by Boris in that
area. This avoids a tip:master conflict as well. The current commit is:
4e2c719782a8 x86/cpu: Help users notice when running old Intel microcode
Thanks,
Ingo
