I just tried building the latest 2.3.37 from ftp.kernel.org for the 8xx.
It failed with the error:
arch/ppc/8xx_io/8xx_io.a: In function `m8xx_cpm_reset':
arch/ppc/8xx_io/8xx_io.a(.text+0x54): undefined reference to `find_pte'
There is no inline find_pte() in include/asm-ppc/pgtable.h as there was
before, yet arch/ppc/8xx_io/commproc.c (and enet.c and fec.c) still try
to use this function. Where has it gone?
What is the currently recommended kernel for 860-based development and
where can I get it?

Not a good idea. There have been many changes lately that I
haven't yet updated in the 8xx tree. I am also learning to
use the new bitkeeper tools, so I am a little cautious about
checking in changes at the moment.

Probably moved to something new and better :-). It looks like
we need to go back to va_to_pte() like was done in the 2.2.xx kernels.

The 2.2.xx kernels are certainly the most stable and recommended
if you are building products. There is a 2.2.13 tar image on
ppc.kernel.org/embedded for 8xx processors. I don't know when
some of the recent changes happened, but the generic 2.3.18
kernel has all of the 8xx changes.
