The recent patch to scrub out ep0 state earlier (to get rid of some of
the enumeration problems that started with about 2.6.6) requires EHCI
to handle endpoint_disable() calls in a slightly different context.

This makes those calls work when an endpoint's QH may still be on the
async schedule, rather than already unlinked.  (The QH stays on the async
schedule for a few milliseconds after it's empty, since it's routine to
issue another request almost immediately.)

This has minor PCI tweaks for the EHCI driver:

  - If the (nonfunctional) AMD 8111 controller shows up, ignore it.
    (Patch from Matt Dharm, with minor coding style tweaks).

  - Delete some code that interprets an EHCI capability code; it
    should be a PCI capability instead.

This patch implements the Windows scheme for USB device initialization.
It also incorporates the change recently posted by David to scrub the
endpoint state following a SET-ADDRESS.  Other noteworthy changes:

	There are two new module parameters to control whether the
	old scheme or the new one is used first and whether the other
	scheme is tried if the first one fails.  Default settings are
	to use the new scheme only.

	hub_set_address() returns 0 immediately if the device is already
	in the USB_STATE_ADDRESS state.

	On the first attempt to read the device descriptor the code
	uses a short 1-second timeout.  This ought to help prevent
	full-speed devices with an 8- or 16-byte maxpacket from
	slowing the procedure down by NAKing the unexpectedly early
	status stage of the transfer.

	For debugging, the ep0 maxpacket value is printed.  It might
	be a good idea to validate it rather than just believing the
	device -- although I haven't heard of any device providing
	an incorrect value other than 0.

This is a collection of updates to the OMAP UDC driver.

  - OMAP-1510 support, including DMA (the DMA controller isn't quite
    the same as on newer chips) but not double buffering.

  - Some PIO work:

      * fix some races that showed up on OMAP-1510

      * tracking down annoying PIO-OUT lossage and making double buffering
        start to behave (needed as fallback if all DMA channels are in use).

  - DMA-IN works on both 1510 and 16xx

Plus minor cleanups.

This updates the dependencies of the HCDs and host-side USB so that:

 - Options for PCI-only HCDs (UHCI and, for now, EHCI) only appear
   systems that actually have PCI.

 - Adding non-PCI bus glue support for another OHCI adapter doesn't
   need involve changing the main USB Kconfig anymore.

 - Minor tweaks to the OMAP support, so OMAP 17xx and 24xx don't need
   additional Kconfig changes and so the H3/17xx gets the ISP1301 too.

This still tries to hide host-side USB config options on systems that
don't offer USB.  While currently convenient, that's a losing proposition
in the long term:  host controllers on chips like SL811 and TD243 can be
put onto any custom board.

Paul Mackerras already did an excellent job of ensuring safe shutdown

the ldisc->hangup and call the existing close routine.

The memset is because it was previously possible to send always the same CIFS
fragment and use this to increase the data counters.  When the data counter
"exceeds" the amount of bytes expected this will return the buffer only
partially initialised...  With findfirst etc requests this should allow
leaking kernel memory content.

The other thing is that the data is only returned when data_tot and parm_tot
both "exceed" the expected values.  Previously it was possible to create a
sequence of CIFS fragments that allowed exceeding the counters.  The calling
functions then would believe they received a number of bytes that does not fit
into the allocated buffer.

ZONE_NORMAL (for example when large amounts of numa remap space are in use)

Since all architectures have these ioctls ("m68knommu" inherits them from
