From f7fe8781749bf2de2ca03147a1691244a7d93ec7 Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Thu, 5 May 2005 16:15:15 -0700 Subject: [PATCH] [PATCH] uml: obvious compile fixes for x86-64 Subarch and x86 regression fixes 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).
