[PATCH v3 0/7] KVM: MMU: fix release pfn in mmu code

[Xiao Guangrong]

Changlog:
changes from Avi's comments:
 - comment for FNAME(fetch)
 - add annotations (__acquires, __releases) for page_fault_start and
   page_fault_end

changes from Marcelo's comments:
 - remove mmu_is_invalid
 - make release noslot pfn path more readable

The last patch which introduces page_fault_start and page_fault_end is
controversial, i hope we can try it since it wrap the ugly pfn release
path up, but i respect your idea. :)

Release pfn in the mmu code is little special for we allow no-slot pfn
go to spte walk on page fault path, that means, on page fault fail path,
we can not directly call kvm_release_pfn_clean.

This patchset fixes the bug which release no-slot pfn on fail path and
clean up all the paths where kvm_release_pfn_clean is called
