The check_intr_schedule() routine in ehci-hcd looks at the wrong
microframes when checking to see if a full-speed or low-speed
interrupt endpoint will fit in the periodic schedule. If the
Start-Split transaction is scheduled for microframe N then the
Complete-Split transactions get scheduled for microframes N+2, N+3, and
N+4. However the code considers N+1, N+2, and N+3 instead.
This patch fixes the limits on the "for" loop and also improves the
use of whitespace.

Host controller drivers use the NS_TO_US macro to convert transaction
times, which are computed in nanoseconds, to microseconds for
scheduling. Periodic scheduling requires worst-case estimates, but
the macro does its conversion using round-to-nearest. This patch
changes it to use round-up, giving a correct worst-case value.

usb_wait_anchor_empty_timeout() should wait till the completion handler
has run. Both the zd1211rw driver and the uas driver (in its task mgmt) depend
on the completion handler having completed when usb_wait_anchor_empty_timeout()
returns, as they read state set by the completion handler after an
usb_wait_anchor_empty_timeout() call.
But __usb_hcd_giveback_urb() calls usb_unanchor_urb before calling the
completion handler. This is necessary as the completion handler may
re-submit and re-anchor the urb. But this introduces a race where the state
these drivers want to read has not been set yet by the completion handler
(this race is easily triggered with the uas task mgmt code).
I've considered adding an anchor_count to struct urb, which would be
incremented on anchor and decremented on unanchor, and then only actually
do the anchor / unanchor on 0 -> 1 and 1 -> 0 transtions, combined with
moving the unanchor call in hcd_giveback_urb to after calling the completion
handler. But this will only work if urb's are only re-anchored to the same
anchor as they were anchored to before the completion handler ran.
And at least one driver re-anchors to another anchor from the completion
handler (rtlwifi).
So I have come up with this patch instead, which adds the ability to
suspend wakeups of usb_wait_anchor_empty_timeout() waiters to the usb_anchor
functionality, and uses this in __usb_hcd_giveback_urb() to delay wake-ups
until the completion handler has run.

Hi Greg,
Here's four patches for 3.12.
The first patch is a bug fix for the USB 2.0 Link PM registers that I sent
out to the list a long time ago (August), but forgot to queue up. The
second and fourth patches are quirks for xHCI hosts. These patches are
marked for stable. The third patch fixes a bug uncovered with sparse.
