[PATCH] Altix: more ACPI PRT support
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(). http://marc.theaimsgroup.com/?l=linux-acpi&m=116680983430121&w=2 Signed-off-by: John Keller <jpk@sgi.com> Acked-by: Len Brown <lenb@kernel.org> Cc: "Luck, Tony" <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
