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).

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.

The fix you pushed (to include l2cr.o for CONFIG_ALL_PPC) is fine.

Paul.
