Introduce vm_fault_hold() and use it to (1) eliminate a long-standing race
condition in proc_rwmem() and to (2) simplify the implementation of the
cxgb driver's vm_fault_hold_user_pages().  Specifically, in proc_rwmem()
the requested read or write could fail because the targeted page could be
reclaimed between the calls to vm_fault() and vm_page_hold().

In collaboration with:	kib@
