From a2f809b08ae4dddc1015c7dcd8659e5729e45b3e Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 27 Apr 2009 18:01:20 -0700 Subject: [PATCH] irq: change ACPI GSI APIs to also take a device argument We want to use dev_to_node() later on, to be aware of the 'home node' of the GSI in question. [ Impact: cleanup, prepare the IRQ code to be more NUMA aware ] Signed-off-by: Yinghai Lu Acked-by: Len Brown Cc: Andrew Morton Cc: Suresh Siddha Cc: "Eric W.
