Subject: [PATCH v2 0/2] CR4 fixes (one is urgent)

Hi Ingo, etc:

Patch 1 fixes a boot regressions that's new in 4.8.

Patch 2 cleans the whole mess up.  It's probably not 4.8 material,
but I'm sending it as part of this series for ease of review.  If
you like, you could apply patch 1 to x86/urgent, merge into x86/asm,
and apply patch 3 on top.

Changes from v1:
 - Drop the patch that was already applied.
 - Get rid of pointless CPUID check, which simplifies it a bit (Borislav)

Andy Lutomirski (2):
  x86/boot: Fix another __read_cr4() case on 486
  x86/asm: Get rid of __read_cr4_safe()
