Convert calls to free_irq so that the second argument is the same as the
last argument of the corresponding call to request_irq. Without this
property, free_irq does nothing.

As the DMA engine API allows DMA channels to be reconfigured on the
fly, we can now support switching the DMA channel configuration to
support SIR transmit DMA without needing to claim an additional
physical DMA channel - thereby using up half the DMA channels just
for one driver.

Convert the sa11x0 IrDA driver to use the sa11x0 DMA engine driver
rather than our own platform specific DMA API.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
The sa11x0-ir device is not the device which is doing the DMA, the
DMA is being performed by a separate DMA engine. Split the struct
device associated with each DMA channel from the main struct device,
but for the time being initialize it from the main struct device.
This is another preparatory step to converting this driver to use the
DMA engine API.

The SIR transmit buffer was being allocated as 4000 bytes. IrDA now
has constants for the buffer sizes, and defines the maximum wrapped
SIR packet to be 4269 bytes as indicated by IRDA_SIR_MAX_FRAME. Use
this definition to allocate the transmit buffer instead.

Convert the sa11x0 IrDA driver to use the scatterlist DMA API. This
is a preparatory patch for converting the driver to use the DMA engine

Ensure that we unmap and free a pending transmit skb when the interface
is stopped. We rearrange the code a little bit to give all places a
similar layout when freeing the skb in both the completion and interface
stop paths - this gives some consistency to the code.
Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
Both the transmit and receive DMA store identical data: the skb, dma
address, and the dma registers. Move this data into its own data
structure. The following replacements were used:
rxskb -> dma_rx.skb
rxbuf_dma -> dma_rx.dma
rxdma -> dma_rx.regs
txskb -> dma_tx.skb
txbuf_dma -> dma_tx.dma
txdma -> dma_tx.regs

There is no reason to export two functions for entering the

doesn't save anything noticeable or removes any race condition.

indicating whether it scheduled out for freezing.
* Update try_to_freeze() to return bool and relay the return value of
__refrigerator() if freezing().
* Convert all refrigerator() users to try_to_freeze().
* Update documentation accordingly.

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.
