This patch (as1461) fixes the unusual_devs entries for the Realtek USB
card reader. They should be ordered by PID, and they should not
override the Subclass and Protocol values provided by the device.
Otherwise a notification about unnecessary entries gets printed in the
kernel log during probing.

GEM wants to mmap the object through the GTT (which avoids aliasing) so we
need to put the object into the GTT before we provide the fault mapping for
it.
While we are at it update the pin interface so that it digs dev out of the
GEM object itself. This provides a rather cleaner API and call environment.
Fix th refcount/on-off confusion in the pin API.
At this point we get a bit further with modetest but if we write to the
new GEM mapping we hang solid and as yet I don't know why.

This patch (as1466) speeds up processing of ehci-hcd's periodic list.
The existing code will pointlessly rescan an interrupt endpoint queue
each time it encounters the queue's QH in the periodic list, which can
happen quite a few times if the endpoint's period is low. On some
embedded systems, this useless overhead can waste so much time that
the driver falls hopelessly behind and loses events.
The patch introduces a "periodic_stamp" variable, which gets
incremented each time scan_periodic() runs and each time the scan
advances to a new frame. If the corresponding stamp in an interrupt
QH is equal to the current periodic_stamp, we assume the QH has
already been scanned and skip over it. Otherwise we scan the QH as
usual, and if none of its URBs have completed then we store the
current periodic_stamp in the QH's stamp, preventing it from being
scanned again.

This patch (as1463) fixes a regression caused by commit
3df7169e73 (OHCI: work around for nVidia
shutdown problem).
The original problem encountered by people using NVIDIA chipsets was
that USB devices were not turning off when the system shut down. For
example, the LED on an optical mouse would remain on, draining a
laptop's battery. The problem was caused by a bug in the chipset; an
OHCI controller in the Reset state would continue to drive a bus reset
signal even after system shutdown. The workaround was to put the
controllers into the Suspend state instead.
It turns out that later NVIDIA chipsets do not suffer from this bug.
Instead some have the opposite bug: If a system is shut down while an
OHCI controller is in the Suspend state, USB devices remain powered!
On other systems, shutting down with a Suspended controller causes the
system to reboot immediately. Thus, working around the original bug
on some machines exposes other bugs on other machines.
The best solution seems to be to limit the workaround to OHCI
controllers with a low-numbered PCI product ID. I don't know exactly
at what point NVIDIA changed their chipsets; the value used here is a
guess. So far it was worked out okay for all the people who have
tested it.
This fixes Bugzilla #35032.

Finger touch events or very quick stylus events on low-quality panels
can cause the tsc2007 to read bogus values. Looking at oscilloscope
snapshots, this seems to be caused by the touch event disappearing
during the measurements. These bogus values result in misclicks, where
the X and Y values deviate from the real position.
Most of these misclicks can be filtered out by setting a low enough
threshold for the maximum resistance (which is loosely the inverse of
the pressure) allowed to consider a set of values valid. Since this
behaviour is largely dependent on the type and quality of the panel,
this commit introduces the max_rt parameter. The default value is kept
at MAX_12BIT.

Commit c21e6beb removed our queue request_fn re-enter
protection, and defaulted to always running the queues from
kblockd to be safe. This was a known potential slow down,
but should be safe.
Unfortunately this is causing big performance regressions for
some, so we need to improve this logic. Looking into the details
of the re-enter, the real issue is on requeue of requests.
Requeue of requests upon seeing a BUSY condition from the device
ends up re-running the queue, causing traces like this:
scsi_request_fn()
scsi_dispatch_cmd()
scsi_queue_insert()
__scsi_queue_insert()
scsi_run_queue()
scsi_request_fn()
...
potentially causing the issue we want to avoid. So special
case the requeue re-run of the queue, but improve it to offload
the entire run of local queue and starved queue from a single
workqueue callback. This is a lot better than potentially
kicking off a workqueue run for each device seen.
This also fixes the issue of the local device going into recursion,
since the above mentioned commit never moved that queue run out
of line.
