KVM: clean up kvm_(set|get)_apic_base
Gleb Natapov [Sun, 5 Aug 2012 12:58:26 +0000 (15:58 +0300)]
kvm_get_apic_base() needlessly checks irqchip_in_kernel although it does
the same no matter what result of the check is. kvm_set_apic_base() also
checks for irqchip_in_kernel, but kvm_lapic_set_base() can handle this
case.
