[PATCH v12 0/8] pv event to notify host when the guest is panicked

[Hu Tao <hutao@cn.fujitsu.com>]

This series implements a new interface, kvm pv event, to notify host when
some events happen in guest. Right now there is one supported event: guest
panic.

changes from v11:

  - add a new patch 'save/load cpu runstate'
  - fix a bug of null-dereference when no -machine option is supplied
  - reserve RUN_STATE_GUEST_PANICKED during migration
  - add doc of enable_pv_event option
  - disable reboot-on-panic if pv_event is on
