The advantage of kcalloc is, that will prevent integer overflows which could
result from the multiplication of number of elements and size and it is also
a bit nicer to read.

With module.h being implicitly everywhere via device.h, the absence
of explicitly including something for EXPORT_SYMBOL went unnoticed.
Since we are heading to fix things up and clean module.h from the
device.h file, we need to explicitly include these files now.
Use the lightweight version of the header that has just THIS_MODULE
and EXPORT_SYMBOL variants.

The situation up to this point meant that module.h was pretty
much everywhere, regardless of whether you asked for it or not.
We are fixing that, so give the USB folks who want it an actual
include of it.

cbaf_cdid_get() is only used in cbaf_wusb_chid_store().
In the original code cbaf_cdid_get() returns either a negative error
code or a small positive value on error. I have changed it to
return -ENOENT if there is not enough data available.
In the original code the caller changed the negative error codes to
positive return values. I've changed it to just return the error
value directly.

Update the USB core to deal with USB 3.0 hubs. These hubs have a slightly
different hub descriptor than USB 2.0 hubs, with a fixed (rather than
variable length) size. Change the USB core's hub descriptor to have a
union for the last fields that differ. Change the host controller drivers
that access those last fields (DeviceRemovable and PortPowerCtrlMask) to
use the union.
Translate the new version of the hub port status field into the old
version that khubd understands. (Note: we need to fix it to translate the
roothub's port status once we stop converting it to USB 2.0 hub status
internally.)
Add new code to handle link state change status. Send out new control
messages that are needed for USB 3.0 hubs, like Set Hub Depth.
This patch is a modified version of the original patch submitted by John
Youn. It's updated to reflect the removal of the "bitmap" #define, and
change the hub descriptor accesses of a couple new host controller
drivers.

In wusb_cluster_id_get(), if no zero bits exist in wusb_cluster_id_table,
find_first_zero_bit() returns CLUSTER_IDS.
But it is impossible to detect that the bitmap is full because there
is an off-by-one error in the return value check. It will cause
unexpected memory access by setting bit out of wusb_cluster_id_table
bitmap, and caller will get wrong cluster id.

For all modules, change <module>-objs to <module>-y; remove
if-statements and replace with lists using the kbuild idiom; move
flags to the top of the file; and fix alignment while trying to
maintain the original scheme in each file.
None of the dependencies are modified.

This patch (as1350) removes all usages of coherent buffers for USB
control-request setup-packet buffers. There's no good reason to
reserve coherent memory for these things; control requests are hardly
ever used in large quantity (the major exception is firmware
transfers, and they aren't time-critical). Furthermore, only seven
drivers used it. We might as well always use streaming DMA mappings
for setup-packet buffers, and remove some extra complexity from
usbcore.
The DMA-mapping portion of hcd.c is currently in flux. A separate
patch will be submitted to remove support for URB_NO_SETUP_DMA_MAP
after everything else settles down. The removal should go smoothly,
as by then nobody will be using it.

The usbcore headers: hcd.h and hub.h are shared between usbcore,
HCDs and a couple of other drivers (e.g. USBIP modules).
So, it makes sense to move them into a more public location and
to cleanup dependency of those modules on kernel internal headers.
This patch moves hcd.h from drivers/usb/core into include/linux/usb/
