Use ata_pad_{alloc,free} in two drivers, to factor out common code.
Add ata_pad_{alloc,free} to two other drivers, which needed the padding
but had not been updated.
This adds support for the Nvidia Geforce 7800 series of cards to the
nvidiafb framebuffer driver. All it does is add the PCI device id for
the 7800, 7800 GTX, 7800 GO, and 7800 GTX GO cards to the module device
table for the nvidiafb.ko driver, so that nvidiafb.ko will actually work
on these cards.
I also added the relevant PCI device ids to linux/pci_ids.h
I tested it on my 7800 GTX here and it works like a charm. I now can
get framebuffer support on this card! Woo hoo!! Nothing like 200x75 text
mode to make your eyes BLEED. ;)

At header fixup time, it is not yet legal to ioremap() PCI

Mellanox has decided that the components of the firmware version are
really meant to be displayed in decimal, e.g. 0x000400070190 is
version 4.7.400. Change the format we use from "%x.%x.%x" to
"%d.%d.%d" to match this convention.

Don't build ipoib_mcast_iter_ functions if CONFIG_INFINIBAND_IPOIB_DEBUG
is not enabled -- their only callers will not be built either.
Also move the prototype for ipoib_open() to ipoib.h to fix a sparse warning.

cfq's add_req_fn callback may invoke q->request_fn directly and
depending on low-level driver used and timing, a queued request may be
finished & deallocated before add_req_fn callback returns. So,
__elv_add_request must not access rq after it's passed to add_req_fn
callback.
This patch moves rq_mergeable test above add_req_fn(). This may
result in q->last_merge pointing to REQ_NOMERGE request if add_req_fn
callback sets it but as RQ_NOMERGE is checked again when blk layer
actually tries to merge requests, this does not cause any problem.

Instead of having ->read_sectors and ->write_sectors, combine the two
into ->sectors[2] and similar for the other fields. This saves a branch
several places in the io path, since we don't have to care for what the
actual io direction is. On my x86-64 box, that's 200 bytes less text in
just the core (not counting the various drivers).

Right now we do it at queueing time, which works alright for reads
(since they are usually sync), but not for async writes since we can
queue io a lot faster than we can complete it. This makes the vmstat
output look extremely bursty.
