usb: hub: rename khubd to hub_wq in documentation and comments
USB hub has started to use a workqueue instead of kthread. Let's update
the documentation and comments here and there.
This patch mostly just replaces "khubd" with "hub_wq". There are only few
exceptions where the whole sentence was updated. These more complicated
changes can be found in the following files:

There's no need to have this file in plat/fpga.h. We can

ARM: OMAP1: OHCI: use platform_data fn ptr to enable OCPI bus
The OMAP1 OHCI driver needs to enable the OCPI IP block before it can
work. Previously, the driver was simply calling a symbol defined in
the OMAP platform code, but this is incorrect: drivers should be fully
decoupled from platform and architecture code.
So instead, modify the driver to call through a platform_data function
pointer instead. We skip any DT aspect, since OMAP1 is not scheduled
to be converted to DT in the near future.
This resolves the following sparse warning:
It also gets rid of a cpu_is_omap16xx() call in a driver.
In the long term, it probably makes sense to move the OCPI bus code to
somewhere under drivers/. This should avoid the whole platform_data/DT
issue with this function.

USB: automatically enable RHSC interrupts
This patch (as1069c) changes the way OHCI root-hub status-change
interrupts are enabled. Currently a special HCD method,
hub_irq_enable(), is called when the hub driver is finished using a
root hub. This approach turns out to be subject to races, resulting
in unnecessary polling.
The patch does away with the method entirely. Instead, the driver
automatically enables the RHSC interrupt when no more status changes
are present. This scheme is safe with controllers using
level-triggered semantics for their interrupt flags.

Revert "USB: don't explicitly reenable root-hub status interrupts"
This reverts commit e872154921a6b5256a3c412dd69158ac0b135176.
Andrey Borzenkov reports that it resulted in a totally hung machine for
him when loading the OHCI driver. Extensive netconsole capture with
SysRq output shows that modprobe gets stuck in ohci_hub_status_data()
when probing and enabling the OHCI controller, see for example
http://lkml.org/lkml/2008/7/5/236
for an analysis.
The problem appears to be an interrupt flood triggered by the commit
that gets reverted, and Andrey confirmed that the revert makes things
work for him again.

USB: don't explicitly reenable root-hub status interrupts
This patch (as1069b) changes the way OHCI root-hub status-change
interrupts are enabled. Currently a special HCD method,
hub_irq_enable(), is called when the hub driver is finished using a
root hub. This approach turns out to be subject to races, resulting
in unnecessary polling.
The patch does away with the method entirely. Instead, the driver
automatically enables the RHSC interrupt when no more status changes
are present. This scheme is safe with controllers using
level-triggered semantics for their interrupt flags.

USB: OHCI: host-controller resumes leave root hub suspended
Drivers in the ohci-hcd family should perform certain tasks whenever
their controller device is resumed. These include checking for loss
of power during suspend, turning on port power, and enabling interrupt
requests.
Until now these jobs have been carried out when the root hub is
resumed, not when the controller is. Many drivers work around the
resulting awkwardness by automatically resuming their root hub
whenever the controller is resumed. But this is wasteful and
unnecessary.
To simplify the situation, this patch (as1066) adds a new core
routine, ohci_finish_controller_resume(), which can be used by all the
OHCI-variant drivers. They can call the new routine instead of
resuming their root hubs. And ohci-pci.c can call it instead of using
its own special-purpose handler.

to be selected at once and the driver is built has module. This case
is quite common in embedded system where you want to handle both the
integrated ohci controller and some extra controller on PCI.
The ohci-hcd.c file now provide the module_init & module_exit and
appropriate driver registering/unregistering is done conditionally,
using #ifdefs.

USB: Properly unregister reboot notifier in case of failure in ehci hcd
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.

USB: OHCI avoids root hub timer polling
This teaches OHCI to use the root hub status change (RHSC) IRQ, bypassing
root hub timers most of the time and switching over to the "new" root hub
polling scheme. It's complicated by the fact that implementations of OHCI
trigger and ack that IRQ differently (the spec is vague there).
Avoiding root hub timers helps mechanisms like "dynamic tick" leave the
CPU in lowpower modes for longer intervals.

[PATCH] fix missing includes
I recently picked up my older work to remove unnecessary #includes of
sched.h, starting from a patch by Dave Jones to not include sched.h
from module.h. This reduces the number of indirect includes of sched.h
by ~300. Another ~400 pointless direct includes can be removed after
this disentangling (patch to follow later).
However, quite a few indirect includes need to be fixed up for this.
In order to feed the patches through -mm with as little disturbance as
possible, I've split out the fixes I accumulated up to now (complete for
i386 and x86_64, more archs to follow later) and post them before the real
patch. This way this large part of the patch is kept simple with only
adding #includes, and all hunks are independent of each other. So if any
hunk rejects or gets in the way of other patches, just drop it. My scripts
will pick it up again in the next round.

[PATCH] USB: Rename hcd->hub_suspend to hcd->bus_suspend
This patch (as580) is perhaps the only result from the long discussion I
had with David about his changes to the root-hub suspend/resume code. It
renames the hub_suspend and hub_resume methods in struct usb_hcd to
bus_suspend and bus_resume. These are more descriptive names, since the
methods really do suspend or resume an entire USB bus, and less likely to
be confused with the hub_suspend and hub_resume routines in hub.c.
It also takes David's advice about removing the layer of bus glue, where
those methods are called. And it implements a related change that David
made to the other HCDs but forgot to put into dummy_hcd.

[PATCH] OHCI PM updates
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...)
Also cleans up a minor debug printk glitch, and switches an mdelay over
to an msleep (how did that stick around for so long?).

all devices were called at SUSPEND_SAVE_STATE level, and finally

compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.
Since this is obsolete infrastructure which is no longer necessary,
we can remove it. Here's an (untested) patch to do exactly that.
