[Xen-devel] [PATCH 02/10] x86/guest-walk: use unambiguous register names

["Jan Beulich" <JBeulich@xxxxxxxx>]

This is in preparation of eliminating the mis-naming of 64-bit fields
with 32-bit register names (eflags instead of rflags etc). Use the
guaranteed 32-bit underscore prefixed names for now where appropriate.
