Avi Kivity b93463aa59 KVM: Accelerated apic support
This adds a mechanism for exposing the virtual apic tpr to the guest, and a
protocol for letting the guest update the tpr without causing a vmexit if
conditions allow (e.g. there is no interrupt pending with a higher priority
than the new tpr).

Avi Kivity b209749f52 KVM: local APIC TPR access reporting facility
Add a facility to report on accesses to the local apic tpr even if the
local apic is emulated in the kernel.  This is basically a hack that
allows userspace to patch Windows which tends to bang on the tpr a lot.

Avi Kivity 565f1fbd9d KVM: Print data for unimplemented wrmsr
This can help diagnosing what the guest is trying to do.  In many cases
we can get away with partial emulation of msrs.

Zhang Xiantao 5736199afb KVM: Move kvm_vcpu_kick() to x86.c
Moving kvm_vcpu_kick() to x86.c. Since it should be
common for all archs, put its declarations in <linux/kvm_host.h>

Move ioapic code to common, since IA64 also needs it.

Avi Kivity edf884172e 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.
