spin_is_locked() is always false on UP kernels: spin_lock_irqsave() does no
locking, so we can't tell whether the lock is held or not. Therefore,
this warning is only valid for SMP kernels.

A few patches ago, I removed the reset_resume callback in this driver.
Now that the usb-serial core supports reset_resume, put this driver
callback back as well, so it should work identically to how it was
originally.
Now if this function really is doing what it should be doing, well,
that's a different story, but we are at least doing the identical thing
that we were before...

The callback is now hooked up for any USB to serial driver that wants
it. We only register the callback if any of the usb-serial structures
want it, this keeps the USB core happy.

For the explicit calls to .udiv/.umul in assembler, I made a
mechanical (read as: safe) transformation. I didn't attempt
to make any simplifications.
In particular, __ndelay and __udelay can be simplified significantly.
Some of the %y reads are unnecessary and these routines have no need
any longer for allocating a register window, they can be leaf
functions.

__ratelimit() can be considered an inverted bool test because
it returns true when not ratelimited. Several tests in the
kernel tree use this __ratelimit() function incorrectly.
No net_ratelimit uses are incorrect currently though.
Most uses of net_ratelimit are to log something via printk or
pr_<level>.
In order to minimize the uses of net_ratelimit, and to start
standardizing the code style used for __ratelimit() and net_ratelimit(),
add a net_ratelimited_function() macro and net_<level>_ratelimited()
logging macros similar to pr_<level>_ratelimited that use the global
net_ratelimit instead of a static per call site "struct ratelimit_state".

Commit 4231d47e6fe69f061f96c98c30eaf9fb4c14b96d(net/usbnet: avoid
recursive locking in usbnet_stop()) fixes the recursive locking
problem by releasing the skb queue lock before unlink, but may
cause skb traversing races:
- after URB is unlinked and the queue lock is released,
the refered skb and skb->next may be moved to done queue,
even be released
- in skb_queue_walk_safe, the next skb is still obtained
by next pointer of the last skb
- so maybe trigger oops or other problems
This patch extends the usage of entry->state to describe 'start_unlink'
state, so always holding the queue(rx/tx) lock to change the state if
the referd skb is in rx or tx queue because we need to know if the
refered urb has been started unlinking in unlink_urbs.
The other part of this patch is based on Huajun's patch:
always traverse from head of the tx/rx queue to get skb which is
to be unlinked but not been started unlinking.
