Subject: [GIT PULL] x86/cpu changes for v5.8

Linus,

Please pull the latest x86/cpu git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-cpu-2020-06-01

   # HEAD: 3d81b3d1e55a518837c3d1f722c6d93abe34aa85 x86/cpu: Use RDRAND and RDSEED mnemonics in archrandom.h

Misc updates:

 - Extend the x86 family/model macros with a steppings dimension,
   because x86 life isn't complex enough and Intel uses steppings to
   differentiate between different CPUs. :-/

 - Convert the TSC deadline timer quirks to the steppings macros.

 - Clean up asm mnemonics.

 - Fix the handling of an AMD erratum, or in other words, fix a kernel erratum.
