[PATCH] uml: obvious compile fixes for x86-64 Subarch and x86 regression fixes

Browse source 
This patch does some totally trivial compilation fixes.  It also restores the
debugregs manipulation, which was commented out simply because it doesn't
compile on x86_64 (we haven't yet implemented there debugregs handling).
