To reproduce this panic consistently, we run an intensive network
application like 'netperf'. After waiting for a couple of seconds,
you will see a stack trace and a kernel panic where we are calling
pci_unmap_single() in ql_poll().
Changes:
1) Check the flags on the Response MAC IO Control block to check for
errors
2) Ensure that if we are on the 4022 we only use one segment
3) Before, we were reading the memory mapped producer index register
everytime we iterated in the loop when clearing the queue. We should
only be iterating to a known point, not as the producer index
is being updated.

This version moves the medium variable to the card specific structure and
changes the GMII_* to BCM54XX_* #defines.
This patch adds improved version of enable_fiber for both the 5421 and
the 5461 phy. It is now possible to specify with these wether you want
autonegotiation or not. This is needed for bladecenter switches where
some expect autonegotiation and some dont seem to like this at all.
Depending on this flag it sets phy->autoneg accordingly for the fiber mode.
More importantly it implements proper read_link and poll_link functions
for both phys which can handle both copper and fiber mode by determining
the medium first and then branching to the required functions. For fiber
they all work fine, for copper they are not tested but return the result
of the genmii_* function anyway which is supposed to work.
The patch moves the genmii_* functions around to avoid foreward declarations.

Separate sata_vsc interrupt handling into a normal (per-port) path and an
error path with the addition of vsc_port_intr and vsc_error_intr
respectively. The error path handles interrupt based
hotplug events which requires the definition of vsc_freeze and vsc_thaw.
Note: vsc_port_intr has a workaround for unexpected interrupts that occur
during polled commands. This fixes a regression between 2.6.19 and 2.6.20.
Changes in take2:
* removed definition of invalid fis bit
* let standard ata-error-handling handle the serror register
* clear all unhandled interrupts
* revert changes to vsc_intr_mask_update (vsc_thaw enables all interrupts)
* use unlikely() for the pci-abort and not-our-interrupt cases in vsc_sata_interrupt

This adds a blacklist to the USB core to handle some autosuspend and
string issues that devices have.
Originally written by Oliver, but hacked up a lot by Greg.

I don't think the current code works with multiple iovecs.
The original would just copy the first part of priv->buf
over and over into multiple iovecs.

The below patch proposes to use USB defines (defined in linux/hid.h)
instead of just plain numbers in the USB_INTERFACE_INFO statements.

This patch (as856) attempts to improve the performance of uhci-hcd by
removing the asynchronous skeleton Queue Headers. They don't contain
any useful information but the controller has to read through them at
least once every millisecond, incurring a non-zero DMA overhead.
Now all the asynchronous queues are combined, along with the period-1
interrupt queue, into a single list with a single skeleton QH. The
start of the low-speed control, full-speed control, and bulk sublists
is determined by linear search. Since there should rarely be more
than a couple of QHs in the list, the searches should incur a much
smaller total load than keeping the skeleton QHs.

The ioctl is commented out for now, until we verify some userspace
