[Xen-devel] [PATCH] Allow ACPI state change with active cpupools

[Juergen Gross <juergen.gross@xxxxxxxxxxxxxx>]

Changing the ACPI state (e.g. power off) while not all cpus are in cpupool 0
will currently crash the hypervisor during disabling the other cpus.
This patch avoids the crash by adding the reason for disabling a cpu (either
permanent e.g. in case of cpu hotplug or temporary in case of ACPI state
change).
This requires an additional parameter for cpu callbacks. All callbacks are
changed to take a structure as parameter instead of only the cpu number.
