KVM: Move irqchip declarations into new ioapic.h and lapic.h This allows reuse of ioapic in ia64. Signed-off-by: Zhang Xiantao <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@qumranet.com>

KVM: unify part of generic timer handling Hide the internals of vcpu awakening / injection from the in-kernel emulated timers. This makes future changes in this logic easier and decreases the distance to more generic timer handling.

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).

KVM: consolidate ioapic/ipi interrupt delivery logic Use kvm_apic_match_dest() in kvm_get_intr_delivery_bitmask() instead of duplicating the same code. Use kvm_get_intr_delivery_bitmask() in apic_send_ipi() to figure out ipi destination instead of reimplementing the logic.
