Subject: [PATCH v3 00/14] KVM: x86: break the xAPIC barrier

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

v3:
[6/14] ignore APIC ID register in x2apic mode [Zhang and Paolo]
[10/14]
* use sub-feature flags -- they allow userspace to postpone enablement
* check invalid msi route in kvm_arch_set_irq_inatomic [Zhang]
[11/14] new

v2: http://www.spinics.net/lists/kvm/msg135220.html


Radim Krčmář (14):
  KVM: x86: bump KVM_SOFT_MAX_VCPUS to 240
  KVM: x86: add kvm_apic_map_get_dest_lapic
  KVM: x86: use physical LAPIC array for logical x2APIC
  KVM: x86: dynamic kvm_apic_map
  KVM: x86: use generic function for MSI parsing
  KVM: x86: use hardware-compatible format for APIC ID register
  KVM: x86: reset APIC ID when enabling LAPIC
  KVM: VMX: optimize APIC ID read with APICv
  KVM: x86: reset lapic base in kvm_lapic_reset
  KVM: pass struct kvm to kvm_set_routing_entry
  KVM: x86: add KVM_CAP_X2APIC_API
  KVM: x86: add a flag to disable KVM x2apic broadcast quirk
  KVM: x86: bump MAX_VCPUS to 288
  KVM: x86: bump KVM_MAX_VCPU_ID to 1023
