[Qemu-devel] [PATCH 0/5 v3] convert system_powerdown command to notifiers

[Igor Mammedov <imammedo@redhat.com>]

global variable qemu_system_powerdown in sysemu.h is the only dep for qemu_irq
and qemu_rise_irq is not a generic way to signal guest that it should shutdown.

replace it by notifiers and allow each implementation to have it's own way
to notify guest.

git repo for testing:
    https://github.com/imammedo/qemu/tree/shutdown_notifier.v3

compile tested:
   target-list=x86_64-linux-user,x86_64-softmmu,sparc-softmmu,arm-softmmu
runtime tested:
   x86_64-softmmu + win7 guest

v3-v2:
    - fixed bisectably issues of series
    - make series independed of cpu_as_device series
 
Igor Mammedov (5):
  Introduce powerdown_notifiers
  acpi: use notifier for signaling guest system_powerdown command
  target-arm: use notifier for signaling guest system_powerdown command
  target-sparc: use notifier for signaling guest system_powerdown
    command
  Cleanup unused global var qemu_system_powerdown
