Pull up revision 1.76 (requested by tls in ticket #1434):
Correct use of MAXBSIZE where MAXPHYS was intended.  This is a necessary
first step towards per-device MAXPHYS, and has the beneficial side effect
of allowing clustering to MAXPHYS even on systems that need to run with
a reduced MAXBSIZE to get more metadata buffers.
