<title>usb: use %*pb[l] to print bitmaps including cpumasks and nodemasks</title>

<id>125918dbd836d19b5dccc2690388b29e575f91a4</id>
<content type='text'>
printk and friends can now format bitmaps using '%*pb[l]'.  cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.

* drivers/uwb/drp.c::uwb_drp_handle_alien_drp() was formatting mas.bm
  into a buffer but never used it.  Removed.

If the endpoint companion descriptor is not the first descriptor in the
extra descriptor buffer of a usb_host_endpoint, the loop in
rpipe_epc_find will get its buffer pointer and remaining size values out
of sync.  The buffer ptr 'itr' is advanced by the descriptor's bLength
field but the remaining size value 'itr_size' is decremented by the
bDescriptorType field which is incorrect.  This patch fixes the loop to
decrement itr_size by bLength as it should.

None of these files are actually using any __init type directives
and hence don't need to include &lt;linux/init.h&gt;.  Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

Use USB_CTRL_SET_TIMEOUT and USB_CTRL_GET_TIMEOUT for USB control
messages instead of an arbitrary 1s timeout value.  This is particularly
useful for WUSB since in the worst case RF scanario, a WUSB device can
be unresponsive for up to 4s and still be connected.

Do not overwrite the multi-byte fields of usb_wa_descriptor with their
cpu format values after reading the descriptor.  Leave the values as
__le16 and swap on use.  This is more consistent with other uses of USB

<title>usb: wusbcore: serialize access to the HWA data out endpoint</title>

<id>679ee475a1c19243c8f50a5a76f6b7519b24c1a3</id>
<content type='text'>
This patch serializes access to the HWA data transfer out (DTO)
endpoint.  This prevents a situation where two transfer requests being
sent concurrently to separate downstream endpoints could interleave
their transfer request and transfer data packets causing data
corruption.  The transfer processing code will now attempt to acquire
the DTO resource before sending a transfer to the HWA.  If it cannot
acquire the resource, the RPIPE that the transfer is assigned to will
be placed on a waiting list.  When the DTO resource is released, the
actor releasing the resource will serivce the RPIPEs that are waiting.
