[Xen-devel] [PATCH] x86 hvm: fix up the unified HAP nested-pagefault handler.

x86 hvm: fix up the unified HAP nested-pagefault handler.
A guest PFN may have been marked dirty and switched to p2m_ram_rw by
another CPU between the VMEXIT and lookup in this handler, so 
we can't just check for p2m_ram_logdirty.  Also, handle_mmio doesn't 
handle passthrough MMIO.
