* 'modsplit-Oct31_2011' of git://git.kernel.org/pub/scm/linux/kernel/git/paulg/linux: (230 commits) Revert "tracing: Include module.h in define_trace.h" irq: don't put module.h into irq.h for tracking irqgen modules. bluetooth: macroize two small inlines to avoid module.h ip_vs.h: fix implicit use of module_get/module_put from module.h nf_conntrack.h: fix up fallout from implicit moduleparam.h presence include: replace linux/module.h with "struct module" wherever possible include: convert various register fcns to macros to avoid include chaining crypto.h: remove unused crypto_tfm_alg_modname() inline uwb.h: fix implicit use of asm/page.h for PAGE_SIZE pm_runtime.h: explicitly requires notifier.h linux/dmaengine.h: fix implicit use of bitmap.h and asm/page.h miscdevice.h: fix up implicit use of lists and types stop_machine.h: fix implicit use of smp.h for smp_processor_id of: fix implicit use of errno.h in include/linux/of.h of_platform.h: delete needless include acpi: remove module.h include from platform/aclinux.h miscdevice.h: delete unnecessary inclusion of module.h device_cgroup.h: delete needless include net: sch_generic remove redundant use of net: inet_timewait_sock doesnt need ... Fix up trivial conflicts (other header files, and removal of the ab3550 mfd driver) in - drivers/media/dvb/frontends/dibx000_common.c - drivers/media/video/{mt9m111.c,ov6650.c} - drivers/mfd/ab3550-core.c - include/linux/dmaengine.h

linux/dmaengine.h: fix implicit use of bitmap.h and asm/page.h

2011-10-31T23:32:30Z

The implicit presence of module.h and all its sub-includes was masking these implicit header usages: include/linux/dmaengine.h:684: warning: 'struct page' declared inside parameter list include/linux/dmaengine.h:684: warning: its scope is only this definition or declaration, which is probably not what you want include/linux/dmaengine.h:687: warning: 'struct page' declared inside parameter list include/linux/dmaengine.h:736:2: error: implicit declaration of function 'bitmap_zero' With input from Stephen Rothwell Signed-off-by: Paul Gortmaker

dmaengine: remove struct scatterlist for header

2011-08-16T11:11:41Z

Commit 90b44f8 introduces dmaengine_prep_slave_single API which adds scatterlist.h in dmaengine.h, so defining struct scatterlist is not required Signed-off-by: Vinod Koul Acked-by: Dan Williams

dmaengine: add helper function for slave_single

2011-08-08T11:18:14Z

For clients which require a single slave transfer and dont want to be bothered about the scatterlist api, this helper gives simple API for this transfer and creates single scatterlist for DMA API Idea from Russell King Signed-off-by: Vinod Koul

net: remove mm.h inclusion from netdevice.h

2011-06-22T02:17:20Z

Remove linux/mm.h inclusion from netdevice.h -- it's unused (I've checked manually). To prevent mm.h inclusion via other channels also extract "enum dma_data_direction" definition into separate header. This tiny piece is what gluing netdevice.h with mm.h via "netdevice.h => dmaengine.h => dma-mapping.h => scatterlist.h => mm.h". Removal of mm.h from scatterlist.h was tried and was found not feasible on most archs, so the link was cutoff earlier. Hope people are OK with tiny include file. Note, that mm_types.h is still dragged in, but it is a separate story. Signed-off-by: Alexey Dobriyan Signed-off-by: David S. Miller

Fix dmaengine_submit() return type

2011-01-15T01:07:49Z

desc->tx_submit's return type is dma_cookie_t, not int. Therefore, dmaengine_submit() should match this return type as it's just wrapping this detail. Signed-off-by: Russell King Signed-off-by: Dan Williams

dmaengine: provide dummy functions for DMA_ENGINE=n

2011-01-03T09:41:40Z

This lets drivers, optionally using the dmaengine, build with DMA_ENGINE unselected. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Dan Williams

async_tx: make async_tx channel switching opt-in

2010-10-08T00:08:32Z

The majority of drivers in drivers/dma/ will never establish cross channel operation chains and do not need the extra overhead in struct dma_async_tx_descriptor. Make channel switching opt-in by default. Cc: Anatolij Gustschin Cc: Ira Snyder Cc: Linus Walleij Cc: Saeed Bishara Signed-off-by: Dan Williams
