[PATCH 1/1] - Altix: more ACPI PRT support

From: John Keller
Date: Fri Feb 02 2007 - 15:54:39 EST


The SN Altix platform does not conform to the
IOSAPIC IRQ routing model. Add code in acpi_unregister_gsi()
to check if (acpi_irq_model == ACPI_IRQ_MODEL_PLATFORM) and
return.

Due to an oversight, this code was not added previously when
similar code was added to acpi_register_gsi().
