Pull KVM fixes from Paolo Bonzini:
 "Quite a few fixes for x86: nested virtualization save/restore, AMD
  nested virtualization and virtual APIC, 32-bit fixes, an important fix
  to restore operation on older processors, and a bunch of hyper-v
  bugfixes. Several are marked stable.

  There are also fixes for GCC warnings and for a GCC/objtool interaction"
