[libvirt] [PATCH 0/2] implement crashloaded event for pvpanic

Guest may handle panic by itself, then just reboot without pvpanic notification. Then We can't separate the abnormal reboot from normal operation. Declear bit 1 for pvpanic as crashloaded event. It should work with guest kernel side. Link: https://lkml.org/lkml/2019/12/14/265 Before running kexec, guest could wirte this bit to notify host side. Host side handles crashloaded event, posts event to upper layer. Then guest side continues to run kexec. Test with libvirt, libvirt could recieve the new event. The patch of libvirt will be sent soon.
