Prevent going idle with softirq pending
The NOHZ patch contains a check for softirqs pending when a CPU goes idle.
The BUG is unrelated to NOHZ, it just was made visible by the NOHZ patch.
The BUG showed up mainly on P4 / hyperthreading enabled machines which lead
the investigations into the wrong direction in the first place. The real
cause is in cond_resched_softirq():
cond_resched_softirq() is enabling softirqs without invoking the softirq
daemon when softirqs are pending. This leads to the warning message in the
NOHZ idle code:
t1 runs softirq disabled code on CPU#0
interrupt happens, softirq is raised, but deferred (softirqs disabled)
t1 calls cond_resched_softirq()
enables softirqs via _local_bh_enable()
calls schedule()
t2 runs
t1 is migrated to CPU#1
t2 is done and invokes idle()
NOHZ detects the pending softirq
Fix: change _local_bh_enable() to local_bh_enable() so the softirq
daemon is invoked.

freezer: close potential race between refrigerator and thaw_tasks
If the freezing of tasks fails and a task is preempted in refrigerator()
before calling frozen_process(), then thaw_tasks() may run before this task is
frozen. In that case the task will freeze and no one will thaw it.
To fix this race we can call freezing(current) in refrigerator() along with
frozen_process(current) under the task_lock() which also should be taken in
the error path of try_to_freeze_tasks() as well as in thaw_process().
Moreover, if thaw_process() additionally clears TIF_FREEZE for tasks that are
not frozen, we can be sure that all tasks are thawed and there are no pending
"freeze" requests after thaw_tasks() has run.

USB: Add support for Olimex arm-usb-ocd JTAG interface serial port
This patch adds support for the serial port on Olimex arm-usb-ocd
JTAG interface.
The device appears as two serial ports, but the first one is reserved
for the JTAG interface. The JTAG interface can be used with OpenOCD
from userspace. For more information, please see:

USB: Fix debug output of ark3116
Fix debug output. Previously, it would output "0xFFFFFFB0" on 32-bit
archs (and probably "0xFFFFFFFFFFFFFFB0" on 64-bits), because buf is
taken as signed char, which is promoted to signed int, while %x always
expects an unsigned int.

USB: remove short initial timeout for device descriptor fetch
This patch (as905) removes a micro-optimization from the hub port
initialization code. Previously we had been using a short timeout on
the first attempt the read the device descriptor; now we will use the
standard timeout length.
It's not clear that the short timeout ever provided any benefit. And
now we know of one case where it actually hurts: The device can't meet
the short timeout and then it gets terminally confused.
This fixes Bugzilla #8444.

USB: remove unneeded WARN_ON
This patch (as883) removes an out-of-date WARN_ON from the main HCD
endpoint-disable routine. The warning is triggered whenever an
endpoint is disabled while the root hub is suspended. In the past
that may not have been legal, but it definitely is legal now. Merely
unbinding a USB driver will do it.
Furthermore, I've never seen any occurrences of this warning that
really did signal an actual bug or error condition. At this point it
has outlived its purpose.

USB: more autosuspend timer stuff
This patch (as879) ties up some loose ends from an earlier patch.
These are things I didn't think to include at the time but which
clearly belonged there.
If an autosuspend fails because driver activity races with
the autosuspend call, restart the autosuspend timer.
When a device is resumed by an external request, it counts
as device activity and should update the last_busy time so
that the next autoresume won't occur immediately.

EHCI: fix problem with BIOS handoff
This patch (as882) fixes a problem with the EHCI BIOS handoff. On my
machine, the BIOS configures the controller and the handoff fails,
leaving the controller configured. During resume-from-disk, this
confuses ehci-hcd into thinking that the controller has not been
tampered with.
The problem is fixed by turning off the Configured Flag whenever a
BIOS handoff is attempted, whether it succeeds or not.
