Move the "global_bh_lock" line downwards a bit into the section that is
protected with #ifdef __SMP__ (along with entries like "global_irq_holder"
and what not).

The RPC errors tend to be due to portmap being started after NFS: this is
a bug in at least the RedHat 4.1 setup (and possibly others). The simplest
solution is to rename the file

/etc/rc.d/rc3.d/S40portmap

to

/etc/rc.d/rc3.d/S13portmap

(so that it gets started before S15nfsfs)

Note that my setup may not be quite standard, so the above may not be
exactly the right numbers, but the idea should be fairly obvious.

When upgrading from 2.0.x to 2.1.x you do need to upgrade various
utilities. The network utilities are one of those. See
Documentation/Changes for some details..
