Xen devel - Mar 2008 - [PATCH] SVM: handle page faults in emaulted instruction fetches

Deal with failures in hvm_copy_from_guest_virt when fetching instructions
in the various SVM emulation paths.  Since we know that the instruction
was fetchable by the hardware, we can usually just return from the VMEXIT
and try again; whatever caused us to fail will cause the hardware to
fail next time and we''ll get the correct exit code.
