[Xen-devel] [PATCH] Fix IPI handling before vcpu launched

["Jiang, Yunhong" <yunhong.jiang@xxxxxxxxx>]

Fix IPI handling before vcpu launched

When sending IPI, the target vcpu may not be launched (like
INIT/Start-Up IPI), and the local apic is not initialized. Fix handling
on such case.

Also fix one bug in apic_round_robin function.
