summary:     Cleanup x86/x86_64 apic.c files.

SAME ISSUE AS BEFORE

x460:

x86_32:

Status:

- dom0 boots fine
- xend loads fine
- single HVM domain loads fine
- Multiple HVM domains load fine
- destruction of any HVM domain causes dom0 to reboot

Issues affecting HVM:

* During xm-test, dom0 reboots. This happens during 
"11_create_concurrent_pos" test case. The destroy call is causing the 
reboot.

Details:


dom0 will also reboot with the following console messages:
