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 <dilinger@queued.net> LKML-Reference: <20101111214526.5de7121b@queued.net> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
