current linuxppc_2_4_devel SMP strangeness.. (processes dieing)

Okay, I pulled 2_4_devel this morning and built and SMP kernel my MTX.. it
booted up, but some weird things started happening..

First, exportfs died on bootup..

Starting internet superserver: inetd.
Exporting directories for NFS kernel
daemon.../etc/rc2.d/S20nfs-kernel-server: line 80:   214 Illegal
instruction     $PREFIX/sbin/exportfs -r
done.
Starting NFS kernel daemon: nfsd mountd.


Then, when I tried to log in over serial console, the login process
appeared to die after I entered 'root'.  If I kept trying, I would
occasional actually get a password prompt.


I think there's something going wrong either in the cache flush avoidance
stuff, or in the generic smp VM.

(I'm going to finally update linuxppc_2_4 for MTX SMP later today, so I'll
can hopefully find out if it's a generic VM problem or not)

It's pre5 ? I think Tom's fix is wrong. It should probably be
copy_user_page or copy_cow_page (I use the last one). Without that,
the cache avoidance will probably win a direct ticket to hell ;)
