USB: fix race between root-hub wakeup & controller suspend
This patch (as1395) adds code to hcd_pci_suspend() for handling wakeup
races. This is another general race pattern, similar to the "open
vs. unregister" race we're all familiar with. Here, the race is
between suspending a device and receiving a wakeup request from one of
the device's suspended children.
In particular, if a root-hub wakeup is requested at about the same
time as the corresponding USB controller is suspended, and if the
controller is enabled for wakeup, then the controller should either
fail to suspend or else wake right back up again.
During system sleep this won't happen very much, especially since host
controllers generally aren't enabled for wakeup during sleep. However
it is definitely an issue for runtime PM. Something like this will be
needed to prevent the controller from autosuspending while waiting for
a root-hub resume to take place. (That is, in fact, the common case,
for which there is an extra test.)

During resume from system sleep this doesn't matter, because the root
hubs will naturally be resumed along with every other device in the
system. However it _will_ matter for runtime PM: If the controller is
suspended and a remote wakeup request is received then the controller
will autoresume, but we need to ensure that the root hub also
autoresumes. Otherwise the wakeup request would be ignored, the
controller would go back to sleep, and the cycle would repeat a large
number of times (I saw this happen before the patch was written).

a long time, and I have not heard any complaints concerning it. By

The point of changing the default is to cause the option to be enabled

like this.

USB: UHCI: acquire spinlock before calling start_rh()
This patch (as1392) fixes a bug in uhci-hcd: The start_rh() routine is
supposed to be called with the private spinlock held. If an IRQ comes
in at just the wrong time, the driver will think the controller has
died when in fact it simply hasn't start yet.
The patch also addresses some issues that may prevent an URB from
being unlinked after the controller has stopped. This is an abnormal
occurrence (ordinarily the controller stops only when the entire bus
is suspended and hence there are no active URBs), so the pathways
haven't gotten much testing. These two changes may be a little more
than is strictly necessary, but clearly they won't hurt.

USB: add check to detect host controller hardware removal
This patch (as1391) fixes a problem that can occur when USB host
controller hardware is hot-unplugged. If no interrupts are generated
by the unplug then the HCD may not realize that the controller is
gone, and the subsequent unbind may hang waiting for interrupts that
never arrive.
The solution (for PCI-based controllers) is to call the HCD's
interrupt handler at the start of usb_hcd_pci_remove(). If the
hardware is gone, the handler will realize this when it tries to read
the controller's status register.

USB: don't stop root-hub status polls too soon
This patch (as1390) fixes a problem that crops up when a UHCI host
controller is unbound from uhci-hcd while there are still some active
URBs. The URBs have to be unlinked when the root hub is unregistered,
and uhci-hcd relies upon root-hub status polls as part of its
unlinking procedure. But usb_hcd_poll_rh_status() won't make those
status calls if hcd->rh_registered is clear, and the flag is cleared
_before_ the unregistration takes place.
Since hcd->rh_registered is used for other things and needs to be
cleared early, the solution is to add a new flag (rh_pollable) and use
it instead. It gets cleared _after_ the root hub is unregistered.
Now that the status polls don't end too soon, we have to make sure
they also don't occur too late -- after the root hub's usb_device
structure or the HCD's private structures are deallocated. Therefore
the patch adds usb_get_device() and usb_put_device() calls to protect
the root hub structure, and it adds an extra del_timer_sync() to
prevent the root-hub timer from causing an unexpected status poll.
This additional complexity would not be needed if the HCD framework
had provided separate stop() and release() callbacks instead of just
stop(). This lack could be fixed at some future time (although it
would require changes to every host controller driver); when that
happens this patch won't be needed any more.

rwsem: wake queued readers when writer blocks on active read lock
This change addresses the following situation:
- Thread A acquires the rwsem for read
- Thread B tries to acquire the rwsem for write, notices there is already
an active owner for the rwsem.
- Thread C tries to acquire the rwsem for read, notices that thread B already
tried to acquire it.
- Thread C grabs the spinlock and queues itself on the wait queue.
- Thread B grabs the spinlock and queues itself behind C. At this point A is
the only remaining active owner on the rwsem.
In this situation thread B could notice that it was the last active writer
on the rwsem, and decide to wake C to let it proceed in parallel with A
since they both only want the rwsem for read.

rwsem: let RWSEM_WAITING_BIAS represent any number of waiting threads
Previously each waiting thread added a bias of RWSEM_WAITING_BIAS. With
this change, the bias is added only once to indicate that the wait list is
non-empty.
This has a few nice properties which will be used in following changes:
- when the spinlock is held and the waiter list is known to be non-empty,
count < RWSEM_WAITING_BIAS <=> there is an active writer on that sem
- count == RWSEM_WAITING_BIAS <=> there are waiting threads and no
active readers/writers on that sem

rwsem: lighter active count checks when waking up readers
In __rwsem_do_wake(), we can skip the active count check unless we come
there from up_xxxx(). Also when checking the active count, it is not
actually necessary to increment it; this allows us to get rid of the read
side undo code and simplify the calculation of the final rwsem count
adjustment once we've counted the reader threads to wake.
The basic observation is the following. When there are waiter threads on
a rwsem and the spinlock is held, other threads can only increment the
active count by trying to grab the rwsem in down_xxxx(). However
down_xxxx() will notice there are waiter threads and take the down_failed
path, blocking to acquire the spinlock on the way there. Therefore, a
thread observing an active count of zero with waiters queued and the
spinlock held, is protected against other threads acquiring the rwsem
until it wakes the last waiter or releases the spinlock.

rwsem: fully separate code paths to wake writers vs readers
This is in preparation for later changes in the series.
In __rwsem_do_wake(), the first queued waiter is checked first in order to
determine whether it's a writer or a reader. The code paths diverge at
this point. The code that checks and increments the rwsem active count is
duplicated on both sides - the point is that later changes in the series
will be able to independently modify both sides.
