This patch fix 2 problems about reading periodic file:

1. The "..." after a interrupt qh is missed because buffer pointer is
   not moved.

2. After setting p.ptr as NULL, its next qh or itd will be omited and
   can't be stored in debug buffer.

This patch is based on the following ideas:

1. Some usb devices (such as usb video class) have endpoints of high
   interval attribute, so reading "periodic" file need more debug buffer
   to accommodate the qh or itd schedule information.  For example, 4KB
   buffer is not enough for a single interrupt qh of 2ms period.

2. print a %p need 16 byte buffer on 64-bits arch, but 8 byte on 32-bits
   arch. Add a extra bonus for 64-bits arch.

This patch (as1134) attempts to improve the way we handle OHCI
controllers with broken Root Hub Status Change interrupt support.  In
these controllers the RHSC interrupt bit essentially never turns off,
making RHSC interrupts useless -- they have to remain permanently
disabled.

Such controllers should still be allowed to turn off their root hubs
when no devices are attached.  Polling for new connections can
continue while the root hub is suspended.  The patch implements this
feature.  (It won't have much effect unless CONFIG_PM is enabled and
CONFIG_USB_SUSPEND is disabled, but since the overhead is very small
we may as well do it.)

This patch (as1118) addresses a problem with certain USB mass-storage
devices.  These devices sometimes return less data than asked for and
then provide no sense data to explain the problem.  Currently
usb-storage leaves it up to the SCSI layer to decide how this should
be handled, and the SCSI layer interprets the lack of sense data to
mean that nothing went wrong.  But if we got less data than required
then something definitely _did_ go wrong, and we should say so.

The patch tells the SCSI layer to retry the command when this sort of
thing happens.  Retrying may not solve the underlying problem, but
it's better than believing that data was transferred when it wasn't.

In case of error, the function backlight_device_register returns an

Add a new mechanism to the composite gadget framework, letting
functions deactivate (and reactivate) themselves.  Think of it
as a refcounted wrapper for the software pullup control.

A key example of why to use this mechanism involves functions that
require a userspace daemon.  Those functions shuld use this new
mechanism to prevent the gadget from enumerating until those daemons
are activated.  Without this mechanism, hosts would see devices that
malfunction until the relevant daemons start.

[This version fixes a thinko in the r8a66597 driver]

This patch let a few discrete USB host controllers drivers (isp116x-hcd,
r8a66597-hcd and sl811-hcd) obtain IRQ flags from their IORESOURCE_IRQ
resource if configured as such, much like it's been done for the smc91x
driver.

It spares people writing support for specific boards the burden to
configure the interrupt controller independantly, and keeps all IRQ
related information in a single resource.

HCD that are integrally part of a SoC have been left aside, as there
is probably no "wiring" options...

Tested on an Xscale PXA-255 based platform with isp116x-hcd.
