| | | | | | | | | | Introduce helper function acpi_set_cpu_present_bit() to simplify acpi_cpu_plug_cb and acpi_cpu_hotplug_init, so that we can keep bit setting in one place.

* acpi: Assert sts array limit on AcpiCpuHotplug_add()Eduardo Habkost2014-03-181-0/+1
| | | | | | | | | | | AcpiCpuHotplug_add() can't handle vCPU arch IDs larger than ACPI_CPU_HOTPLUG_ID_LIMIT. Instead of corrupting memory in case the vCPU ID is too large, use g_assert() to ensure we are not over the limit.
