From 3948ec9406f9a60a43d63f23f6f5284db6529b9c Mon Sep 17 00:00:00 2001 From: John Keller Date: Fri, 22 Dec 2006 11:50:04 -0600 Subject: ACPI: Altix: ACPI _PRT support Provide ACPI _PRT support for SN Altix systems. The SN Altix platform does not conform to the IOSAPIC IRQ routing model, so a new acpi_irq_model (ACPI_IRQ_MODEL_PLATFORM) has been defined. The SN platform specific code sets acpi_irq_model to this new value, and keys off of it in acpi_register_gsi() to avoid the iosapic code path.
