This series allows userspace to create and send interrupts to VCPUs with
APIC ID > 255.

v2:
dropped "KVM: x86: use u16 for logical VCPU mask in lapic" [Paolo]
[1,5,8,9,12/13] r-b Paolo
[7,10,13/13] new [Paolo]
[2/13] do not point to out-of-scope value (return &src) [Paolo]
[3/13]
* split from the next patch [Paolo]
* handle all sizes of the lapic array [Paolo]
[4/13]
* replaced size with max_apic_id to minimize chances of overflow [Andrew]
* fixed allocation size [Paolo]
[6/13]
* removed an obvious comment about recalculate_apic_id in state_set
* refactor kvm_apic_state_fixup and kvm_apic_post_state_restore [Paolo]
* reset apic id on xapic->disabled->xapic transitions [Paolo]
[11/13]
* pass struct kvm into kvm_set_msi_irq [Paolo]
* trace address_hi [David]
* use hex dst, like other tracepoins
* strict reserved MSI bits checking [Paolo]
* loose reserved capability bits checking [Paolo]
* improved documentation [Paolo]
