2007-10-11mmc: don't use weight32()Nicolas Pitre
Using weight32() to determine if a value is a power of 2 is a rather heavi weight solution. The classic idiom is (x & (x - 1)) == 0, but the kernel already provide a is_power_of_2 function for it. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>

2007-10-10pxamci: support arbitrary block sizeNicolas Pitre
The PXA has two transmit FIFOes, each32 byte deep. when one FIFO is full and the other one has been transmitted, they are automatically swapped and DMA is triggered for another 32 byte burst. However, when there is less than 32 bytes left to send, the FIFO swap has to be done manually. This is required for some SDIO transfers which are not required to be multiples of 32 bytes. A DMA completion interrupt is set for each descriptor which length isn't a multiple of 32 in order to force the FIFO swap. While at it, the DMA interrupt handler has been made a bit more resilient against errors. Signed-off-by: Nicolas Pitre <nico@marvell.com> Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2007-10-10V4L/DVB (6316): Change list_for_each+list_entry to list_for_each_entryTrent Piepho
The rest of V4L files. There is one list_for_each+list_entry in cpia_pp.c that wasn't changed because it expects the loop iterator to remain NULL if the list is empty. A bug in vivi is fixed; the 'safe' version needs to be used because the loop deletes the list entries. Simplify a second loop in vivi and get rid if an un-used variable in that loop.

2007-10-10V4L/DVB (6313): ivtv: Replace list_for_each+list_entry with list_for_each_entryTrent Piepho
Also fixed a few cases of cut&paste errors where 'buf' would be set to the first entry in the list prior to be used as the loop iterator. In one case the value of buf was used before it was changed, but the rest were unnecessary. There was one list_for_each+list_entry loop that wasn't changed, since it depending on the loop iterator being left as NULL if the list was empty.

In the past, videobuf_queue_init were used to initialize PCI DMA videobuffers. This patch renames it, to avoid confusion with the previous kernel API, doing: s/videobuf_queue_init/void videobuf_queue_core_init/ Also, the operations is now part of the function parameter. The function will also add a test if this is defined, otherwise producing BUG. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2007-10-10V4L/DVB (6283): videobuf: Remove references to old Kconfig option nameTrent Piepho
CONFIG_VIDEO_BUF_DVB became CONFIG_VIDEOBUF_DVB. But in these cases, it makes more sense to use CONFIG_VIDEO_SAA7134_DVB or CONFIG_VIDEO_CX88_DVB_MODULE depending on the driver. The reference in cx23885.h should just be removed, as the code there needs to be included if DVB is on or off. I do not think you can even compile the cx23885 driver without DVB. It's clearly just leftover from when the file was obvious copied from the cx88 driver (which is not mentioned in the copyright BTW).
