MFC revision 1.198
 Remove unnecessary check for curthread == NULL.

MFC revision 1.197
 System maps are prohibited from mapping vnode-backed objects.  Take
 advantage of this restriction to avoid acquiring and releasing Giant when
 wiring pages within a system map.

MFC revisions 1.193 and 1.194
 Further reduce the use of Giant by vm_fault(): Giant is held only when
 manipulating a vnode, e.g., calling vput().  This reduces contention for
 Giant during many copy-on-write faults, resulting in some additional
 speedup on SMPs.
