Preparatory patch for the source merge of arch/i386 and arch/x86_64
into arch/x86. This allows to keep the original arch directories as
stubs for the main Makefiles, Kconfigs et. al during the transition
phase while having the code in the new arch/x86 directory.

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.

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.

A couple loops weren't changed because they expected the loop iterator

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.

As bi_end_io is only called once when the reqeust is complete,
the 'size' argument is now redundant. Remove it.
Now there is no need for bio_endio to subtract the size completed
from bi_size. So don't do that either.
While we are at it, change bi_end_io to return void.

The only caller of bio_endio that does not pass the full bi_size
is end_that_request_first. Also, no ->bi_end_io method is really
interested in bi_size being decremented.
So move the decrement and related code into ll_rw_blk and merge it
with order_bio_endio to form req_bio_endio which does endio functionality
specific to request completion.
As some ->bi_end_io methods do check bi_size of 0, we set it thus for
now, but that will go in the next patch.

The entire function of flush_dry_bio_endio is to undo the effects
of bio_endio (when called on a barrier request). So remove the
function and the call to bio_endio.
