[PATCH 0/3] x86/MSR: Add a MSR write callback

[Borislav Petkov]

From: Borislav Petkov <bp@xxxxxxx>

Hi all,

here's a small set which adds a callback to execute when a MSR is
written. Patch 3 explains the need for it.

Thx.

Borislav Petkov (3):
  x86/msr: Pass a single MSR value to __rwmsr_on_cpus() too
  x86/msr: Add wrmsrl_val_on_cpus()
  x86/msr: Add an MSR write callback
