From 4722d194e648fb5755faecee895b96b26f9732f3 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Fri, 12 Nov 2010 05:45:26 +0000 Subject: x86, of: Define irq functions to allow drivers/of/* to build on x86 - Define a stub irq_create_of_mapping for x86 as a stop-gap solution until drivers/of/irq is further along. - Define irq_dispose_mapping for x86 to appease of_i2c.c These are needed to allow stuff in drivers/of/ to build on x86. This stuff will eventually get replaced; quoting Grant, "The long term plan is to have the drivers/of/ code handling the mapping intelligently like powerpc currently does." But for now, just provide these functions. Signed-off-by: Andres Salomon LKML-Reference: <20101111214526.5de7121b@queued.net> Signed-off-by: H.
