[PATCH] kexec: x86_64: restore apic virtual wire mode on shutdown
When coming out of apic mode attempt to set the appropriate apic back into virtual wire mode. This improves on previous versions of this patch by by never setting bot the local apic and the ioapic into veritual wire mode. This code looks at data from the mptable to see if an ioapic has an ExtInt input to make this decision. A future improvement is to figure out which apic or ioapic was in virtual wire mode at boot time and to remember it. That is potentially a more accurate method, of selecting which apic to place in virutal wire mode.
