[PATCH]x86:x2apic: Disable x2apic on x86-32 permanently
x86:x2apic: Disable x2apic on x86-32 permanently
x2apic initialization on x86_32 uses vcpu pointer before it is initialized. As x2apic is unlikely to be used on x86_32, this patch disables x2apic permanently on x86_32. It also asserts the sanity of vcpu pointer before dereference to prevent further misuse.
