Set the ehci->resuming flag for the port we receive a remote
wakeup on so that resume signalling can be completed.
Without this, the root hub timer will not fire again to check
if the resume was completed and there will be a never-ending wait on
on the port.
This effect is only observed if the HUB IRQ IN does not come after we
have initiated the port resume.

This patch was tested on 3.10.1 kernel.
Same models of Petatel NP10T modems have different device IDs.
Unfortunately they have no additional revision information on a board
which may treat them as different devices. Currently I've seen only
two NP10T devices with various IDs. Possibly Petatel NP10T list will
be appended upon devices with new IDs will appear.

The hub driver was recently changed to use "global" suspend for system
suspend transitions on non-SuperSpeed buses. This means that we don't
suspend devices individually by setting the suspend feature on the
upstream hub port; instead devices all go into suspend automatically
when the root hub stops transmitting packets. The idea was to save
time and to avoid certain kinds of wakeup races.
Now it turns out that many hubs are buggy; they don't relay wakeup
requests from a downstream port to their upstream port if the
downstream port's suspend feature is not set (depending on the speed
of the downstream port, whether or not the hub is enabled for remote
wakeup, and possibly other factors).
We can't have hubs dropping wakeup requests. Therefore this patch
goes partway back to the old policy: It sets the suspend feature for a
port if the device attached to that port or any of its descendants is
enabled for wakeup. People will still be able to benefit from the
time savings if they don't care about wakeup and leave it disabled on
all their devices.
In order to accomplish this, the patch adds a new field to the usb_hub
structure: wakeup_enabled_descendants is a count of how many devices
below a suspended hub are enabled for remote wakeup. A corresponding
new subroutine determines the number of wakeup-enabled devices at or
below an arbitrary suspended USB device.
This should be applied to the 3.10 stable kernel.

The USB_MAXCHILDREN symbol is used in include/uapi/linux/usb/ch11.h, a
user-mode header, even though it is defined in include/linux/usb.h,
which is kernel-only. This causes compile-time errors when user
programs try to #include linux/usb/ch11.h.
This patch fixes the problem by moving the definition of USB_MAXCHILDREN
into ch11.h. It also gets rid of unneeded parentheses.

Per dwc3 2.50a spec, the is_devspec bit is used to distinguish the
Device Endpoint-Specific Event or Device-Specific Event (DEVT). If the
bit is 1, the event is represented Device-Specific Event, then use
[7:1] bits as Device Specific Event to marked the type. It has 7 bits,
and we can see the reserved8_31 variable name which means from 8 to 31
bits marked reserved, actually there are 24 bits not 25 bits between
that. And 1 + 7 + 24 = 32, the event size is 4 byes.
So in dwc3_event_type, the bit mask should be:
is_devspec [0] 1 bit
type [7:1] 7 bits
reserved8_31 [31:8] 24 bits
This patch should be backported to kernels as old as 3.2, that contain

Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
disable migration. But the SLUB code is relatively lockless, and the
spin_locks there are raw_spin_locks (not converted to mutexes), thus I
believe this bug can happen in mainline without -rt features. The -rt
patch is just good at triggering mainline bugs ;-)
Anyway, looking at where this crashed, it seems that the page variable
can be NULL when passed to the node_match() function (which does not
check if it is NULL). When this happens we get the above panic.
As page is only used in slab_alloc() to check if the node matches, if
it's NULL I'm assuming that we can say it doesn't and call the
__slab_alloc() code. Is this a correct assumption?

changes to try to make device destruction more deterministic.
