5dbc1ca26a Add an option "-a" to present the local apic in the XAPIC mode instead of the 
default X2APIC mode to the guest.

bc269b51af Add support for trapping MMIO writes to local apic registers and emulating them. 
The default behavior is still to present the local apic to the guest in the
x2apic mode.

c34be7b811 Add an explicit exit code 'SPINUP_AP' to tell the controlling process that an 
AP needs to be activated by spinning up an execution context for it.

The local apic emulation is now completely done in the hypervisor and it will
detect writes to the ICR_LO register that try to bring up the AP. In response
to such writes it will return to userspace with an exit code of SPINUP_AP.

c0caea8c2f Restructure the x2apic access code in preparation for supporting memory mapped 
access to the local apic.

The vlapic code is now aware of the mode that the guest is using to access the
local apic.

9f0c999f81 MSI-x interrupt support for PCI pass-thru devices. 
Includes instruction emulation for memory r/w access. This
opens the door for io-apic, local apic, hpet timer, and
legacy device emulation.

8c8399924a Get rid of redundant initialization of 'dmask'. It was being re-initialized 
shortly afterwards.
