* KVM: Move arch dependent files to new directory arch/x86/kvm/Avi Kivity2008-01-301-289/+0
| | | | | | | This paves the way for multiple architecture support. Note that while ioapic.c could potentially be shared with ia64, it is also moved. Signed-off-by: Avi Kivity <avi@qumranet.com>

* KVM: MMU: Fix inherited permissions for emulated guest pte updatesAvi Kivity2008-01-301-2/+2
| | | | | | | | When we emulate a guest pte write, we fail to apply the correct inherited permissions from the parent ptes. Now that we store inherited permissions in the shadow page, we can use that to update the pte permissions correctly. Signed-off-by: Avi Kivity <avi@qumranet.com>

| | | | | | | | Split kvm_arch_vcpu_create() into kvm_arch_vcpu_create() and kvm_arch_vcpu_setup(), enabling preemption notification between the two. This mean that we can now do vcpu_load() within kvm_arch_vcpu_setup(). Signed-off-by: Avi Kivity <avi@qumranet.com>

* KVM: Replace 'light_exits' stat with 'host_state_reload'Avi Kivity2008-01-301-1/+1
| | | | | | | | This is a little more accurate (since it counts actual reloads, not potential reloads), and reverses the sense of the statistic to measure a bad event like most of the other stats (e.g. we want to minimize all counters). Signed-off-by: Avi Kivity <avi@qumranet.com>
