Subject[PATCH 0/3] CR4 fixes (some are urgent)
Date
Hi Ingo, etc:

Patches 1 and 2 fix boot regressions. Patch 1 needs to be
backported. Patch 2 doesn't because the regression is new in 4.8
(although it's probably unobservable because the regression fixed in
patch 1 also prevented bootup on affected CPUs).

Patch 3 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 patches 1 and 2 to x86/urgent, merge into
x86/asm, and apply patch 3 on top.

Andy Lutomirski (3):
x86/init: Fix cr4_init_shadow() on CR4-less machines
x86/boot: Fix another __read_cr4() case on 486
x86/asm: Get rid of __read_cr4_safe()
