xhci: Streams and UAS cleanups, misc cleanups for 3.15

Browse source 
Hi Greg,
 
 Here's 76 patches to queue to usb-next for 3.15.
 
 The bulk of this rather large pull request is the UAS driver cleanup, the
 xHCI streams fixes, and the new userspace API for usbfs to be able to use
 and alloc/free bulk streams.  I've hammered on these changes, and the UAS
 driver seems solid.  The performance numbers are pretty spiffy too:
 
 root@xanatos:~# echo 3 > /proc/sys/vm/drop_caches; dd if=/dev/sdb of=/dev/null bs=4k count=1000M iflag=count_bytes
 256000+0 records in
 256000+0 records out
 1048576000 bytes (1.0 GB) copied, 3.28557 s, 319 MB/s
 
 That's about 100 MB/s faster than my fastest Bulk-only-Transport mass
 storage drive.
 
 There's a couple of miscellaneous cleanup patches and non-urgent bug fixes
 in here as well:
 
 7969943789 xhci: add the meaningful IRQ description if it is empty
 bcffae7708 xhci: Prevent runtime pm from autosuspending during initialization
 e587b8b270 xhci: make warnings greppable
 25cd2882e2 usb/xhci: Change how we indicate a host supports Link PM.
