Arg!  I just fixed this, but the problem is this.  I took
arch/ppc/kernel/l2cr.o out of the always-compiled list, and made it
compile only for CONFIG_6xx (which is 6xx/7xx/74xx/82xx) since only
740/750 and 74xx (more or less) can make use of this.  The problem is
that Power3 and Power4 pretend to be CONFIG_ALL_PPC, so that they can

Well POWER3/4 aren't just pretending to be CONFIG_ALL_PPC, they *are*
CONFIG_ALL_PPC since they *are* CHRP machines.  Not all CHRPs are 6xx
(actually POWER3 is a PPC630 or PPC630+ so it *is* 6xx in a sense).

Well, pretending is a bad choice of words.  They are real chrp machines,
but they aren't 'ALL_PPC', since you can't run on a power3 and a 604 :)

be a chrp machine easily.  The best way to fix this, I think would be to
make the arch/ppc/kernel/chrp_* files compile without needed pmac_*,
so that these machines could just work.  Paul, does this sound like
a sane plan to you?

Nope. :)  Not unless we want to start having separate configs for
prep, pmac and chrp again like we used to.  Which is not impossible
but it would be a fair bit of work.

Well, I don't think it will be as bad as that.  It _should_ be possible
to split them out, and move the functions it uses from pmac_setup.c into
a common file.  If I have time I'll play with it sometime and post patches.
If it can be done cleanly, I don't think it'd be a bad idea, but...
