Subject: [PATCH 0/2] Fix the #PF injection logic for smaller MAXPHYADDR in nested.

KVM shall inject the #PF directly to L2 when L2 has a smaller MAXPHYADDR
and L1 has no desire to intercept it, yet currently the #PF will be
delivered to L1 anyway.

Patch 1 fixes this, by initializing the 'fault' variable.
Patch 2 is just a cleanup for the comments.

Yu Zhang (2):
  KVM: X86: Initialize 'fault' in kvm_fixup_and_inject_pf_error().
  KVM: X86: Fix the comments in prepare_vmcs02_rare()
