V4L/DVB (9300): pvrusb2: Fix deadlock problem
Fix deadlock problem in 2.6.27 caused by new USB core behavior in
response to a USB device reset request. With older kernels, the USB
device reset was "in line"; the reset simply took place and the driver
retained its association with the hardware. However now this reset
triggers a disconnect, and worse still the disconnect callback happens
in the context of the caller who asked for the device reset. This
results in an attempt by the pvrusb2 driver to recursively take a
mutex it already has, which deadlocks the driver's worker thread.
(Even if the disconnect callback were to happen on a different thread
we'd still have problems however - because while the driver should
survive and correctly disconnect / reconnect, it will then trigger
another device reset during the repeated initialization, which will
then cause another disconect, etc, forever.) The fix here is simply
to not attempt the device reset (it was of marginal value anyway).

PCI: introduce an pci_ioremap(pdev, barnr) function
A common thing in many PCI drivers is to ioremap() an entire bar. This
is a slightly fragile thing right now, needing both an address and a
size, and many driver writers do.. various things there.
This patch introduces an pci_ioremap() function taking just a PCI device
struct and the bar number as arguments, and figures this all out itself,
in one place. In addition, we can add various sanity checks to this
function (the patch already checks to make sure that the bar in question
really is a MEM bar; few to no drivers do that sort of thing).
Hopefully with this type of API we get less chance of mistakes in
drivers with ioremap() operations.

- when a pci_slot is released, look for all the pci_dev's it was

PCI: change MSI-x vector to 32bit
We are using 28bit pci (bus/dev/fn + 12 bits) as irq number, so the
cache for irq number should be 32 bit too.

PCI PM: Introduce function pci_wake_from_d3
Many device drivers use the following sequence of statements to enable
the device to wake up the system while being in the D3_hot or D3_cold
low power state:
pci_enable_wake(pdev, PCI_D3hot, 1);
pci_enable_wake(pdev, PCI_D3cold, 1);
However, the second call is not necessary if the first one succeeds (the
ordering of the statements above doesn't matter here) and it may even be
harmful, because we are not supposed to enable PME# after the wake-up
power has been enabled for the device.
To allow drivers to overcome this problem, introduce function
pci_wake_from_d3() that will enable the device to wake up the system
from any of D3_hot and D3_cold as long as the wake-up from at least one
of them is supported.

PCI: allow quirks to be compiled out
This patch adds the CONFIG_PCI_QUIRKS option which allows to remove all
the PCI quirks, which are not necessarily used on embedded systems when
PCI is working properly. As this is a size-reduction option, it depends
on CONFIG_EMBEDDED. It allows to save almost 12 kilobytes of kernel
code:

PCI: Check dynids driver_data value for validity
Only accept dynids whose driver_data value matches one of the driver's

PCI: remove dynids.use_driver_data
The driver flag dynids.use_driver_data is almost consistently not set,
and causes more problems than it solves. It was initially intended as a
flag to indicate whether a driver's usage of driver_data had been
carefully inspected and was ready for values from userspace. That audit
was never done, so most drivers just get a 0 for driver_data when new
IDs are added from userspace via sysfs. So remove the flag, allowing
drivers to see the data directly (a followon patch validates the passed
driver_data value against what the drivers expect).
