Subject: [PATCH 0/5] KVM: some x86 MMU cleanup and new tracepoints

Given the attention to pgprintk, here are the patches I had locally
to add new tracepoints to __direct_map, FNAME(fetch) and mmu_set_spte().
These tracepoints actually come from a recent debugging session, so they
have proved their usefulness. :)  And because I'm feeling both lazy *and*
generous, I'm including a couple free cleanups from the series that I was
debugging!

Junaid Shahid (1):
  kvm: x86: Do not release the page inside mmu_set_spte()

Paolo Bonzini (4):
  KVM: x86: make FNAME(fetch) and __direct_map more similar
  KVM: x86: remove now unneeded hugepage gfn adjustment
  KVM: x86: change kvm_mmu_page_get_gfn BUG_ON to WARN_ON
  KVM: x86: add tracepoints around __direct_map and FNAME(fetch)
