This patch updates x2apic initializaition code to allow x2apic on VMware platform even without interrupt remapping support. The hypervisor_x2apic_available hook was added in x2apic initialization code and used by KVM and XEN, before this. I have also cleaned up that code to export this hook through the hypervisor_x86 structure. Compile tested for KVM and XEN configs, this patch doesn't have any functional effect on those two platforms. On VMware platform, verified that x2apic is used in physical mode on products that support this.
