This patch (as954) implements a suggestion of David Brownell's.  Now
the host controller drivers are responsible for linking and unlinking
URBs to/from their endpoint queues.  This eliminates the possiblity of
strange situations where usbcore thinks an URB is linked but the HCD
thinks it isn't.  It also means HCDs no longer have to check for URBs
being dequeued before they were fully enqueued.

In addition to the core changes, this requires changing every host
controller driver and the root-hub URB handler.  For the most part the
required changes are fairly small; drivers have to call
usb_hcd_link_urb_to_ep() in their urb_enqueue method,
usb_hcd_check_unlink_urb() in their urb_dequeue method, and
usb_hcd_unlink_urb_from_ep() before giving URBs back.  A few HCDs make
matters more complicated by the way they split up the flow of control.

In addition some method interfaces get changed.  The endpoint argument
for urb_enqueue is now redundant so it is removed.  The unlink status
is required by usb_hcd_check_unlink_urb(), so it has been added to
urb_dequeue.

The ZF Micro OHCI controller exhibits unexpected behavior that seems to be
related to high load.  Under certain conditions, the controller will
complete a TD, remove it from the endpoint's queue, and fail to add it to
the donelist. This causes the endpoint to appear to stop responding. Worse,
if the device is removed while in that state, OHCI will hang while waiting
for the orphaned TD to complete.  The situation is not recoverable without
rebooting.

This fix enhances the scope of the existing OHCI_QUIRK_ZFMICRO flag:

 1. A watchdog routine periodically scans the OHCI structures to check
    for orphaned TDs. In these cases the TD is taken back from the
    controller and completed normally.

 2. If a device is removed while the endpoint is hung but before the
    watchdog catches the situation, any outstanding TDs are taken back
    from the controller in the 'sanitize' phase.

The ohci-hcd driver used to print "INTR_SF lossage" in this situation;
this changes it to the universally accurate "ED unlink timeout".  Other
instances of this message presumably have different root causes.

Both this Compaq quirk and a NEC quirk are now properly compiled out for
non-PCI builds of this driver.

This patch (as887) changes the way ehci-hcd and ohci-hcd handle a loss
of VBUS power during suspend.  In order for the USB-persist facility
to work correctly, it is necessary for low- and full-speed devices
attached to a high-speed port to be handed back to the companion
controller during resume processing.

This entails three changes: adding code to ehci-hcd to perform the
handover, removing code from ohci-hcd to turn off ports during
root-hub reinit, and adding code to ohci-hcd to turn on ports during
PCI controller resume.  (Other bus glue resume methods for platforms
supporting high-speed controllers would need a similar change, if any
existed.)

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead
of passing regs around manually through all ~1800 interrupt handlers in the
Linux kernel.

The regs pointer is used in few places, but it potentially costs both stack
space and code to pass it around.  On the FRV arch, removing the regs parameter
from all the genirq function results in a 20% speed up of the IRQ exit path
(ie: from leaving timer_interrupt() to leaving do_IRQ()).

Where appropriate, an arch may override the generic storage facility and do
something different with the variable.  On FRV, for instance, the address is
maintained in GR28 at all times inside the kernel as part of general exception
handling.

Having looked over the code, it appears that the parameter may be handed down
through up to twenty or so layers of functions.  Consider a USB character
device attached to a USB hub, attached to a USB controller that posts its
interrupts through a cascaded auxiliary interrupt controller.  A character
device driver may want to pass regs to the sysrq handler through the input
layer which adds another few layers of parameter passing.

I've build this code with allyesconfig for x86_64 and i386.  I've runtested the
main part of the code on FRV and i386, though I can't test most of the drivers.
I've also done partial conversion for powerpc and MIPS - these at least compile
with minimal configurations.

This will affect all archs.  Mostly the changes should be relatively easy.
Take do_IRQ(), store the regs pointer at the beginning, saving the old one:

	struct pt_regs *old_regs = set_irq_regs(regs);

And put the old one back at the end:

	set_irq_regs(old_regs);

Don't pass regs through to generic_handle_irq() or __do_IRQ().

In timer_interrupt(), this sort of change will be necessary:

	-	update_process_times(user_mode(regs));
	-	profile_tick(CPU_PROFILING, regs);
	+	update_process_times(user_mode(get_irq_regs()));
	+	profile_tick(CPU_PROFILING);

I'd like to move update_process_times()'s use of get_irq_regs() into itself,
except that i386, alone of the archs, uses something other than user_mode().

Some notes on the interrupt handling in the drivers:

 (*) input_dev() is now gone entirely.  The regs pointer is no longer stored in
     the input_dev struct.

 (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking.  It does
     something different depending on whether it's been supplied with a regs
     pointer or not.

 (*) Various IRQ handler function pointers have been moved to type
     irq_handler_t.

If some problem occurs during ehci startup, for instance, request_irq fails,
echi hcd driver tries it best to cleanup, but fails to unregister reboot
notifier, which in turn leads to crash on reboot/poweroff.

The following patch resolves this problem by not using reboot notifiers
anymore, but instead making ehci/ohci driver get its own shutdown method.  For
PCI, it is done through pci glue, for everything else through platform driver
glue.

One downside: sa1111 does not use platform driver stuff, and does not have its
own shutdown hook, so no 'shutdown' is called for it now.  I'm not sure if it
is really necessary on that platform, though.

This makes OHCI use the driver model wakeup control bits for its root hub
(e.g. disable on amd756, because of chip erratum) and for the controller
itself.  It no longer uses the hcd glue bits with those roles, and depends
on the previous patch making the root hub available earlier.

Note that on most platforms (boot code properly setting the RWC bit) this
gives a partial workaround for the way PCI isn't currently flagging devices
that support PME# signals.  (Because of odd PCI init sequencing on PPC.)
That's because many OHCI controllers support "legacy PCI PM" ... without
involving any PCI PM capability.

Alan, please verify the UHCI bit I did, I only verified that it builds.

I also made the patch a little bit more "safer" by making sure the store

I set the flag and drop the spinlock.

Without this patch, you cannot reliably sleep/wakeup any recent Mac, and
I suspect PCs have some more sneaky issues too (they don't frankly crash

This simplifies the OHCI root hub suspend logic:

 - Uses new usbcore root hub calls to make autosuspend work again:
	* Uses a newish usbcore root hub wakeup mechanism,
	  making requests to khubd not keventd.
	* Uses an even newer sibling suspend hook.

 - Expect someone always made usbcore call ohci_hub_suspend() before bus
   glue fires; and that ohci_hub_resume() is only called after that bus
   glue ran.  Previously, only CONFIG_USB_SUSPEND promised those things.
   (Includes updates to PCI and OMAP bus glue.)

 - Handle a not-noticed-before special case during resume from one of
   the swsusp snapshots when using "usb-handoff":  the controller isn't
   left in RESET state.  (A bug to fix in the usb-handoff code...)
