This reverts commit a069c266ae.
It turns ou that not only was it missing a case (XFS) that needed it,
but perhaps more importantly, people sometimes want to enable new
modules that they hadn't had enabled before, and if such a module uses
list_sort(), it can't easily be inserted any more.
So rather than add a "select LIST_SORT" to the XFS case, just leave it
compiled in. It's not all _that_ big, after all, and the inconvenience
isn't worth it.

The caller of usbfs_conn_disc_event() in some cases (but not always)
already holds usbfs_mutex, so trying to protect the event counter with
that lock causes nasty deadlocks.
The problem was introduced by commit 554f76962d ("USB: Remove BKL from
poll()") when the BLK protection was turned into using the mutex instead.
So fix this by using an atomic variable instead. And while we're at it,
get rid of the atrocious naming of said variable and the waitqueue it is
associated with.
This also cleans up the unnecessary locking in the poll routine, since
the whole point of how the pollwait table works is that you can just add
yourself to the waiting list, and then check the condition you're
waiting for afterwards - avoiding all races.
It also gets rid of the unnecessary dynamic allocation of the device
status that just contained a single word. We should use f_version for
this, as Dmitry Torokhov points out. That simplifies everything
further.

There are subsystems whose power management callbacks only need to
invoke the callbacks provided by device drivers. Still, their system
sleep PM callbacks should play well with the runtime PM callbacks,
so that devices suspended at run time can be left in that state for
a system sleep transition.
Provide a set of generic PM callbacks for such subsystems and
define convenience macros for populating dev_pm_ops structures.
