We just fix up the reference parameters as the others are dealt with by arithmetic promotion rules and don't cause warnings. This removes warnings like this: arch/powerpc/platforms/ps3/interrupt.c:327: warning: passing argument 1 of 'lv1_construct_event_receive_port' from incompatible pointer type Also, these: drivers/ps3/ps3-vuart.c:462: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type drivers/ps3/ps3-vuart.c:592: warning: passing argument 4 of 'ps3_vuart_raw_read' from incompatible pointer type Signed-off-by: NStephen Rothwell <sfr@canb.auug.org.au> Acked-by: NGeoff Levand <geoffrey.levand@am.sony.com> Signed-off-by: NBenjamin Herrenschmidt <benh@kernel.crashing.org>

Currently if you don't specify a match callback for your irq_host it's assumed you match everything. This is a kind of opt-out approach, and turns out to be the exception rather than the rule. So change the semantics to be opt-in, ie. you don't match anything unless you provide a match callback. This in itself isn't very useful, but will allow us to provide a default match implementation in a subsequent patch.

The majority of irq_host implementations (3 out of 4) are associated with a device_node, and need to stash it somewhere. Rather than having it somewhere different for each host, add an optional device_node pointer to the irq_host structure.

PS3 vuart updates to reflect the new PS3 unified device support. - Move vuart devices to the PS3 system bus. - Replace use of ps3_vuart_port_device with ps3_system_bus_device. - Make the PS3 vuart bus driver a loadable module. - Add remove() and shutdown() routines. - Move ps3_vuart_work into ps3_vuart_port_priv.tx_list. - Remove redundant spinlock ps3_vuart_work.lock. - No longer free ps3_vuart_port_device.priv on shutdown. - Cleanup Kconfig defs. - Export symbols needed for modular port drivers. - Arrange to use port numbers found in repository. - Fix bugs in ps3_vuart_read_async() and polled reading - Cleanup handling of shared interrupt with ps3_vuart_bus_interrupt_get() and ps3_vuart_bus_interrupt_put() - Add more comments to vuart.c.

Rework the PS3 system bus to unify device support. - DMA region sizes must be a power of two - storage bus DMA updates: - Small fixes for the PS3 DMA core: o fix alignment bug o kill superfluous test o indentation o spelling o export ps3_dma_region_{create,free}() - ps3_dma_region_init(): o Add `addr' and `len' parameters, so you can create a DMA region that does not cover all memory (use `NULL' and `0' to cover all memory). This is needed because there are not sufficient IOMMU resources to have all DMA regions cover all memory. o Uninline - Added remove and shutdown routines to all drivers. - Added loadable module support to all drivers. - Added HV calls for iopte management (needed by sound driver).
