[PATCH 0/5] x86/CPU: Improve AMD Erratum 400 workaround

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Hi,

here's the final version of the pile we've been working on for a while
now, trying to remove that rdmsr on the idle path.

@jolsa: just wait until it lands in tip and then you can run it on your
box.

Thanks.

Borislav Petkov (2):
  x86/cpufeature: Provide helper to set bugs bits
  x86/amd: Simplify AMD E400 aware idle routine

Thomas Gleixner (3):
  x86/bugs: Separate AMD E400 erratum and C1E bug
  x86/amd: Check for the C1E bug post ACPI subsystem init
  x86: Remove empty idle.h header
