From edf884172e9828c6234b254208af04655855038d Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Sun, 16 Dec 2007 11:02:48 +0200 Subject: KVM: Move arch dependent files to new directory arch/x86/kvm/ This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved.
