kthread: export kthread functions

The s-Par visornic driver, currently in staging, processes a queue being
serviced by the an s-Par service partition.  We can get a message that
something has happened with the Service Partition, when that happens, we
must not access the channel until we get a message that the service
partition is back again.

The visornic driver has a thread for processing the channel, when we get
the message, we need to be able to park the thread and then resume it
when the problem clears.

We can do this with kthread_park and unpark but they are not exported
from the kernel, this patch exports the needed functions.
