If any thread takes more than one kmap() at a time, it is deadlockable.
Because there is a finite pool of kmaps. Everyone can end up holding
one or more kmaps, then waiting for someone else to release one.
Duplicating page_waitqueue() is bad. Exporting it is probably bad too.
Better would be to help us work out why the core kernel infrastructure is
unsuitable, then make it suitable.
