Subject: [PATCH 0/4] x86/microcode: Some 4.10 fixes

From: Borislav Petkov <bp@...e.de>

Hi,

here are 4 fixes for tip/urgent which address issues Boris and Jürgen
reported while testing latest upstream on xen.

As a result, let's just not load it at all when running on a hypervisor
and be done with the d*icking around.

Please apply,
thanks.

Boris Ostrovsky (1):
  x86/microcode/AMD: Use native_cpuid() in load_ucode_amd_bsp()

Borislav Petkov (3):
  x86/microcode/AMD: Make find_proper_container() sane again
  x86/microcode/AMD: Sanitize apply_microcode_early_amd()
  x86/microcode/AMD: Do not load when running on a hypervisor
