[Bugfix 3/3] xen/irq: Override ACPI IRQ management callback __acpi_unregister_gsi

2015-01-19 Thread Jiang Liu
Xen overrides __acpi_register_gsi and leaves __acpi_unregister_gsi as is. That means, an IRQ allocated by acpi_register_gsi_xen_hvm() or acpi_register_gsi_xen() will be freed by acpi_unregister_gsi_ioapic(), which may cause undesired effects. So override __acpi_unregister_gsi to NULL for safety. S
