The attached patch: 1. Converts the shutdown driver and xend to use the store instead of control messages, 2. Includes Anthony''s xenstore notification code, and 3. Changes xend so that sysrq''s are no longer sent as "special case" shutdown messages. Store keys are cheap, so making the sysrq delivery less obscure is good. I think I have made all of the

...ts unregistered on runtime suspend, and we also want to intercept ACPI_VIDEO_NOTIFY_PROBE when runtime suspended. Signed-off-by: Hans de Goede <hdegoede at redhat.com> --- Note that ACPI_VIDEO_NOTIFY_PROBE currently is a private define in drivers/acpi/acpi_video.c, since it is passed to acpi_notifier_call_chain() it really should be in a public header, so I've submitted a patch to the acpi subsys to move it to include/acpi/video.h . In the mean time this patch defines it with a #ifndef guard to allow merging without introducing inter subsys dependencies. I will submit a follow up patch removing...
