XEN: Grant table address, xen_hvm_resume_frames, is a phys_addr not a pfn
From: Eric Trudeau <etrudeau@broadcom.com> xen_hvm_resume_frames stores the physical address of the grant table. englighten.c was incorrectly setting it as if it was a page frame number. This caused the table to be mapped into the guest at an unexpected physical address. Additionally, a warning is improved to include the grant table address which failed in xen_remap.
