## Intel-Kernel Issue
#I5ODSC

## Test

1, build and boot succeed with CONFIG_SMP enabled or disabled.
2, Use IPI benchmark (https://lore.kernel.org/kvm/20171219085010.4081-1-ynorov@caviumnetworks.com) to do unicast IPI testing ("Normal IPI" case in the benchmark):
 - With host disabled IPI virtualization, and guest enable x2apic mode, we can see a lot of MSR_WR_VMEXITs
 - With host enabled IPI virtualization, and guest enable x2apic mode, MSR_WR_VMEXITs caused by IPI disappears.

## Known Issue
N/A

## Default Config Change
