Rafael J. Wysocki 3a2d5b7001 PM: Introduce PM_EVENT_HIBERNATE callback state
During the last step of hibernation in the "platform" mode (with the
help of ACPI) we use the suspend code, including the devices'
->suspend() methods, to prepare the system for entering the ACPI S4
system sleep state.

But at least for some devices the operations performed by the
->suspend() callback in that case must be different from its operations
during regular suspend.

For this reason, introduce the new PM event type PM_EVENT_HIBERNATE and
pass it to the device drivers' ->suspend() methods during the last phase
of hibernation, so that they can distinguish this case and handle it as
appropriate.  Modify the drivers that handle PM_EVENT_SUSPEND in a
special way and need to handle PM_EVENT_HIBERNATE in the same way.

These changes are necessary to fix a hibernation regression related
to the i915 driver (ref. http://lkml.org/lkml/2008/2/22/488).

This patch (as1033) adds a quirks entry and an unusual_devs entry for
the Actions Semiconductor flash drive.  This device has a 64-byte

Oddly enough, the reporter's logs show that when the device was
plugged in at boot time, it changes its behavior completely -- it uses
a different product ID, product string descriptor, and bDeviceClass.

Alan Stern a462549b6a USB: usb-storage: don't clear-halt when Get-Max-LUN stalls
This patch (as1032) removes the Clear-Halt calls in
usb_stor_Bulk_max_lun().  Evidently some devices (such as the Oracom
MP3 player) really don't like to receive these requests when their
bulk endpoints aren't halted.

The only reason for adding them originally was to get an ancient
ZIP-100 drive to work.  But since this device has only a single LUN,
we don't need to send it a Get-Max-LUN request at all.  Adding an
unusual_devs entry for the ZIP-100 with the SINGLE_LUN flag set will
cause this step to be skipped.

David Brownell c06d4dcf50 usb: ehci should use u16 for isochronous intervals
While most isochronous endpoints have short polling intervals, the
EHCI driver won't necessarily handle larger ones correctly.

This patch switches to use a "u16" to represent those periods, not
a u8, since it can always work:  the largest expressible period
is 2^15 units ... not the previous too-short limit of 128 frames
(full or low speeds) or microframes (high speed, 32 frames).

This bug is essentially theoretical, since the few ISO endpoints
I've seen which don't use one transfer per frame are high speed
ones using more than that (including high bandwidth, 24 KB/msec).
