Fix single linked list manipulation for sub_driver. If the remving entry
is not on the head of the sub_driver list, it goes into infinate loop.
Though that infinite loop doesn't happen. Because the only user of
acpi_pci_register_dirver() is acpiphp.

The blk_rq_unmap_user() API is not very nice. It expects the caller to
know that rq->bio has to be reset to the original bio, and it will
silently do nothing if that is not done. Instead make it explicit that
we need to pass in the first bio, by expecting a bio argument.

This patch fixes a stupid bug. Sometime during the 2tb enhancement I ended up
replacing the macros XFER_READ and XFER_WRITE with h->cciss_read and
h->cciss_write respectively. It seemed to work somehow at least on x86_64 and
ia64. I don't know how. But people started complaining about command timeouts
on older controllers like the 64xx series and only on ia32. This resolves the
issue reproduced in our lab. Please consider this for inclusion.
Thanks,

There was an off-by-one bug in bnx2_tx_avail(). If the tx ring is
completely full, the producer and consumer indices may be apart by
256 even though the ring size is only 255. One entry in the ring is
unused and must be properly accounted for when calculating the number
of available entries. The bug caused the tx ring entries to be
reused by mistake, overwriting active entries, and ultimately causing
it to crash.
This bug rarely occurs because the tx ring is rarely completely full.
We always stop when there is less than MAX_SKB_FRAGS entries available
in the ring.

The UDMA66 VIA hardware has no controller side cable detect bits we can
use. This patch minimally fixes the problem by reporting unknown in this
case and using drive side detection.
The old drivers/ide code does some additional tricks but those aren't
appropriate now we are in -rc.
Without this update UDMA66 via controllers run slowly. They don't fail so
it's a borderline call whether this is -rc material or not.

Reboot hangs on LPARs without diag308 support. The reason for this is,
that before the reboot is done, the channel subsystem is shut down.
During the reset on each possible subchannel a "store subchannel" is
done. This operation can end in a program check interruption, if the
specified subchannel set is not implemented by the hardware. During
the reset, currently we do not have a program check handler, which
leads to the described kernel bug. We install now a new program check
handler for the reboot code to fix this problem.

adds support for a number of keys from the USB HID Usage Table
(http://www.usb.org/developers/devclass_docs/Hut1_12.pdf).
It also adds several new key codes. Most of them are used on real world

I also added KEY_ZOOMRESET as it is possible to have a inet keyboard and a
