[IA64] - Altix: hotplug after intr redirect can crash system
When redirecting a device interrupt on SN, not all links between platform specific structures are being updated. This can result in a system crash if an interrupt redirection is followed by an unplug of that device. The complete fix also requires a prom update. Though, this patch is backward compatable and not dependent on the prom patch. Signed-off-by: John Keller <jpk@sgi.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
