In an attempt to ensure memory allocation from the local node, the pci
driver temporarily replaces the current task's memory policy with the
system default policy. Trying to be a good citizen, the driver then call's
mpol_get() on the new policy. When it's finished probing, it undoes the
'_get by calling mpol_free() [on the system default policy] and then
restores the current task's saved mempolicy.
A couple of issues here:
1) it's never necessary to set a task's mempolicy to the
system default policy in order to get system default
allocation behavior. Simply set the current task's
mempolicy to NULL and allocations will fall back to
system default policy.
2) we should never [need to] call mpol_free() on the system
default policy. [I plan on trapping this with a VM_BUG_ON()
in a subsequent patch.]
This patch removes the calls to mpol_get() and mpol_free()
and uses NULL for the temporary task mempolicy to effect
default allocation behavior.

While most isochronous endpoints have short polling intervals, the
EHCI driver won't necessarily handle larger ones correctly.
This patch switches to use a "u16" to represent those periods, not
a u8, since it can always work: the largest expressible period
is 2^15 units ... not the previous too-short limit of 128 frames
(full or low speeds) or microframes (high speed, 32 frames).
This bug is essentially theoretical, since the few ISO endpoints
I've seen which don't use one transfer per frame are high speed
ones using more than that (including high bandwidth, 24 KB/msec).

This has some bugfixes for the EHCI driver's ISO transfer scanning
logic. It was leaving ITDs and SITDs on the schedule too long, for
a few different reasons, which caused trouble.
(a) Look at all microframes for high speed transfers, not just
the ones we expect to have finished. This way transfers
ending mid-frame will complete without needing another IRQ.
This also minimizes bogus scheduling underruns (e.g. EL2NSYNC).
(b) When we encounter an ISO transfer (either speed, but this
hits mostly at full speed) that's not yet been completed,
immediately stop scanning; we've caught up to the hardware,
no matter what other indications might say.
(c) Always clean up ITDs (for high speed transfers) when the HC
is no longer running.
I'm not sure whether the last one has been observed before, but both
the others have been reported with "real world" audio and video code.

Small updates to the EHCI driver's ISO support:
- Get rid of the Kconfig option for full speed ISO. It may
not be perfect yet, but it hasn't appeared to be dangerous
and pretty much every configuration wants it.
- Instead of two places to disable an empty periodic schedule
after an ISO transfer completes, just have one.
- After the periodic schedule is disabled, we can short-circuit
the schedule scan ... it can't possibly have more work to do.
Assuming a typical config with split iso enabled, the only change
in behavior should be almost unobservable: quicker termination
of periodic scans when the schedule gets emptied.

In the EHCI driver, itd->usecs[8] is used in periodic_usecs(), indexed by
uframe. For an ITD's unused uframes it is 0, else it contains the same

This patch exports two statistics to userspace:
/sys/bus/usb/device/.../power/connected_duration
/sys/bus/usb/device/.../power/active_duration
connected_duration is the total time (in msec) that the device has
been connected. active_duration is the total time the device has not
been suspended. With these two statistics, tools like PowerTOP can
calculate the percentage time that a device is active, i.e. not
suspended or auto-suspended.
Users can also use the active_duration to check if a device is actually
autosuspended. Currently, they can set power/level to auto and
power/autosuspend to a positive timeout, but there's no way to know from
userspace if a device was actually autosuspended without looking at the
dmesg output. These statistics will be useful in creating an automated

Fix a small glitch noted by Yannick Cote. There is no endpoint number
six, so if a (broken) host wrongly tried to change or read status of
that endpoint, the driver could access reserved register space.

drivers/usb/serial/usb-serial::serial_open() sets port->tty
The check for NULL is bogus. This patch removes the check.

Fix potential (never-observed) oops on rare error path,
bugzilla #9594. Fix uses the same test as used earlier.
Also make the adjacent "else" block look like an "else" block
instead of hiding like a bug.

Kernel bugzilla entry #9569 reports a potential OOPS in some code
supporting the integrated root hub TT support used on ARC/TDI
derived cores. (This seems to have been a longstanding issue.)
This patch cleans up usage of urb->dev->tt to avoid that potential
oops and also fixes some overly long lines.

This adds a workaround for an issue reported with ISO transfers
on some EHCI controllers, most recently with VIA KT800 and PS3
EHCI silicon.
The issue is that the silicon doesn't necessarily seem to be done
using ISO DMA descriptors (itd, sitd) when it marks them inactive.
(One theory is that the ill-defined mechanism where hardware caches
periodic transfer descriptors isn't invalidating their state...)
With such silicon, quick re-use of those descriptors makes trouble.
Waiting until the next frame seems to be a sufficient workaround.
This patch ensures that the relevant descriptors aren't available
for immediate re-use. It does so by not recycling them until after
issuing the completion callback which would reuse them by enqueueing
an URB and thus (re)allocating ISO DMA descriptors.

Some boards (like e.g. Tosa) invert the VBUS-detection signal:
it's low when a host is supplying VBUS, and high otherwise.
Allow specifying whether gpio_vbus value is inverted.

Without this fix, the pl2303 usb-serial adapter would not suspend properly
unless it had been opened first. A pl2303 type_1 chip will still break if the
system is hibernated while the RS-232 connector is powered by another system.
This was broken before, and a reset resume does not fix it. All other suspend
and autosuspend scenarios work with ATEN pl2303 adaptors with HX and type_1 chips.
