kernel dumping case.
ata_completed() may initiate ata_reinit() on error, that may lead to drives
attach or detach. Attach and detach are sending requests to drives and sleep
waiting for results. But ata_finish() can be called directly from
interrupt handler where sleeping is prohibited, so we must break this chain
somewhere. This place seems to fit best.
Disable MSI for nVidia MCP51 controller. Enabling MSI there leads to
unexpected errors and timeouts, that should not happen even if interrupts
are not working completely.
required to make 3CR990 familiy controllers run on NV flash
firmware version 03.001.008.
The latest firmware added HMAC digest information so teach txp(4)
to pass them to sleep image before downloading is started.
While I'm here restore previous IMR/IER register if firmware
downloading have failed.

- We don't need to exit the Giant mutex when sleeping. This is done
automatically. Replace Giant by NULL mutex for all control requests in the
enumeration path.
- Optimise away duplicate alternate interface selection requests in USB Host
mode.

Improvements to "usb2_transfer_setup()" and "usb2_transfer_unsetup()". Set
"ppxfer[n]" when the transfer setup is complete to prevent races. Remove
redundant NULL-checks from "usb2_transfer_unsetup()".

- The software computed HID size is not always correct, because the algoritm
does not handle unsorted HID descriptors.
- Change the way we obtain the report ID.
- Use the X/Y/Z+button locations instead for report ID source for ums.
- Add more range checks.
- Remove Microsoft Mouse quirks. If the positions are moduloed the report
length multiplied by 8, the values seem correct.
- Some minor style changes.

o add ah_configPCIE and ah_disablePCIE for drivers to configure PCIE
power save operation (modeled after ath9k, may need changes)
o add private state flag to indicate if device is PCIE (replaces private
hack in 5212 code)
o add serdes programming ini bits for 5416 and later parts and setup
for each part (5416 and 9160 logic hand-crafted from existing routines);
5212 remains open-coded but is now hooked in via ah_configPCIE
o add PCIE workaround gunk
o add ar5416AttachPCIE for iodomatic code used by 5416 and later parts
o add output mux support
o gpio pin count is chip-dependent
o 9280 and 9285 do input handling different
o hookup gpio interrupts
o no need to save/restore soft led state around reset
register instead of AAC_RX_FWSTATUS, as that is the way it's done in
Adaptec's vendor driver and in the Linux drivers. (The same applies
to aac_rkt_get_fwstatus as well.)
However, a concern has been raised about the compatibility of this
change and old hardware / firmware versions. In the absense of
specific information, revert to the original behaviour if the firmware
does not support the "New comm." interface. Users of old cards or
firmware haven't reported the problems that are potentially solved by
switching to OMR0.
