Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".
In other words, we are adopting the same practice in Linux kernel.

On UEFI UP2 board, APs might execute HLT before SOS kernel INIT them.
After SOS kernel take over and will re-init the APs directly. The flows
from HV perspective is like:
HLT trap:
wait_event(VCPU_EVENT_VIRTUAL_INTERRUPT) -> sleep_thread
SOS kernel INIT, SIPI APs:
pause_vcpu(ZOMBIE) -> sleep_thread
-> reset_vcpu
-> launch_vcpu -> wake_vcpu
However, the last wake_vcpu will fail because the cpu event
VCPU_EVENT_VIRTUAL_INTERRUPT had not got signaled.
This patch will reset all vcpu events in reset_vcpu. If the thread was
previously waiting for a event, its waiting status will be cleared and
launch_vcpu will wake it to running.

This simple event implemention can only support exclusive waiting
at same time. It mainly used by thread who want to wait for special event
happens.
Thread A who want to wait for some events calls
wait_event(struct sched_event *);
Thread B who can give the event signal calls
signal_event(struct sched_event *);
