Subject: x86/guest-walk: use unambiguous register names
X-Git-Tag: archive/raspbian/4.11.1-1+rpi1~1^2~66^2~3073
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=1622b8543378e41e01fb8bc197acd0c1d9f79a16;p=xen.git

x86/guest-walk: use unambiguous register names

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.
