flexible, we can use its actual size.

This triggered a few compiler warning messages when these fields were

This patch (as1204) adds a software retry mechanism to ehci-hcd. It
gets invoked when the driver encounters transaction errors on an
asynchronous endpoint. On many systems, hardware deficiencies cause
such errors to occur if one device is unplugged while the host is
communicating with another device. With the patch, the failed
transactions are retried and generally succeed the second or third
time through.
This is based on code originally written by Koichiro Saito.

This patch (as1225) fixes a bug in ehci-hcd. The condition for
whether unlinked QHs can become IDLE should not be that the controller
is halted, but rather that the controller isn't running. In other
words when the root hub is suspended, the hardware doesn't own any
QHs.
This fixes a problem that can show up during hibernation: If a QH is
only partially unlinked when the root hub is frozen, then when the
root hub is thawed the QH won't be in the IDLE state. As a result it
can't be used properly for new URB submissions.

ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing
isochronous URB's kref.counts incrementing once per usb_submit_urb() call.
The culprit is *usb being set to NULL when usb_put_urb() is called after URB
is given back.
Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb()
nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd.
Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a
stream finishes.

Currently ITDs are immediately recycled whenever their URB completes.
However, EHCI hardware can sometimes remember some ITD state. This
means that when the ITD is reused before end-of-frame it may sometimes
cause the hardware to reference bogus state.
This patch defers reusing such ITDs by moving them into a new ehci member
cached_itd_list. ITDs resting in cached_itd_list are moved back into their
stream's free_list once scan_periodic() detects that the active frame has
elapsed.
This makes the snd_usb_us122l driver (in kernel since .28) work right
when it's hooked up through EHCI.

If a USB PCI controller is behind a cardbus bridge, we are trying to
restore its configuration registers too early, before the cardbus
bridge is operational. To fix this, call pci_restore_state() from
usb_hcd_pci_resume() and remove usb_hcd_pci_resume_early() which is
no longer necessary (the configuration spaces of USB controllers that
are not behind cardbus bridges will be restored by the PCI PM core
with interrupts disabled anyway).
This patch fixes the regression from 2.6.28 tracked as
http://bugzilla.kernel.org/show_bug.cgi?id=12659
[ Side note: the proper long-term fix is probably to just force the
unplug event at suspend time instead of doing a plug/unplug at resume

This patch adds support for the FHCI USB controller, as found
in the Freescale MPC836x and MPC832x processors. It can support
Full or Low speed modes.
Quite a lot the hardware is doing by itself (SOF generation, CRC
generation and checking), though scheduling and retransmission is on
software's shoulders.
This controller does not integrate the root hub, so this driver also
fakes one-port hub. External hub is required to support more than
one device.

Commit a0d4922da2
(USB: fix up suspend and resume for PCI host controllers) attempted
to fix the suspend-resume of PCI USB controllers, but unfortunately
it did that incorrectly and interrupts are left enabled by the USB
controllers' ->suspend_late() callback as a result. This leads to
serious problems during suspend which are very difficult to debug.
Fix the issue by removing the ->suspend_late() callback of PCI
USB controllers and moving the code from there to the ->suspend()
callback executed with interrupts enabled. Additionally, make
the ->resume() callback of PCI USB controllers execute
pci_enable_wake(dev, PCI_D0, false) to disable wake-up from the
full power state (PCI_D0).

This patch (as1199) changes the initial wakeup settings for PCI USB
host controllers. The controllers are marked as capable of waking the
system, but wakeup is not enabled by default.
It turns out that enabling wakeup for USB host controllers has a lot
of bad consequences. As the simplest example, if a USB mouse or
keyboard is unplugged immediately after the computer is put to sleep,
the unplug will cause the system to wake back up again! We are better
off marking them as wakeup-capable and leaving wakeup disabled.

This patch (as1192) rearranges the USB PCI host controller suspend and

Use pci_wake_from_d3() for enabling and disabling wakeup,
instead of pci_enable_wake().
Carry out the actual state change while interrupts are

Change the order of the preparations to agree with the
general recommendation for PCI devices, instead of
messing around with the wakeup settings while the device
is in D3.
In .suspend:
Call the underlying driver to disable IRQ
generation;
pci_wake_from_d3(device_may_wakeup());
pci_disable_device();
In .suspend_late:
pci_save_state();
pci_set_power_state(D3hot);
(for PPC_PMAC) Disable ASIC clocks
In .resume_early:
(for PPC_PMAC) Enable ASIC clocks
pci_set_power_state(D0);
pci_restore_state();
In .resume:
pci_enable_device();
pci_set_master();
pci_wake_from_d3(0);
Call the underlying driver to reenable IRQ
generation
