From 1747fb71fd7c9389696e91f354d2f841b5c85790 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 6 Sep 2007 01:21:32 +1000 Subject: KVM: Hoist SVM's get_cs_db_l_bits into core code. SVM gets the DB and L bits for the cs by decoding the segment. This is in fact the completely generic code, so hoist it for kvm-lite to use.
