[Xen-devel] [PATCH] Handle PoD case in hvm_hap_nested_page_fault()

[George Dunlap <dunlapg@xxxxxxxxx>]

The new combined nested page fault handling doesn't consider the case
where the gfn_to_mfn() translation caused the page to be transparently
populated.  Attached patch is one solution; a more robust solution
would be to take the access type (read or write) and check it against
the type returned by gfn_to_mfn() to handle spurious NPFs as well (if
such things ever happen).
