Subject: [PATCH 0/3] x86/mce: Fix more noinstr fun

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

Hi all,

here's a second small set of fixes for objtool noinstr validation issues
in the MCE code.

It goes ontop of tip:locking/core where there are some more commits
changing generic helpers to be always inlined.

As always, comments and suggestions are appreciated.

Thx.

Borislav Petkov (3):
  cpumask: Add a x86-specific cpumask_clear_cpu() helper
  x86/ptrace: Always inline v8086_mode() for instrumentation
  x86/mce: Use arch atomic and bit helpers
