Subject: [PATCH v2 00/13] KVM: x86: break the xAPIC barrier

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]
