		 * With x2apic, architectural x2apic MSRs are equivalent to the

		 * the apic accessors.  The only exception is

		 * hv_apic_eoi_write, because it benefits from lazy EOI when

		 * available, but it works for both xapic and x2apic modes.

		 * When in x2apic mode, don't use the Hyper-V specific APIC

		 * accessors since the field layout in the ICR register is

		 * different in x2apic mode. Furthermore, the architectural

		 * x2apic MSRs function just as well as the Hyper-V

		 * synthetic APIC MSRs, so there's no benefit in having

		 * separate Hyper-V accessors for x2apic mode. The only

		 * exception is hv_apic_eoi_write, because it benefits from

		 * lazy EOI when available, but the same accessor works for

		 * both xapic and x2apic because the field layout is the same.
