Hi All,
What follows is an updated version of copy_4K_page that has been tuned
for the Cell processor. With this new routine it was found that the
system time measured when compiling a 2.6.26 pseries_defconfig was
reduced by ~10s:
mainline (2.6.27-rc1-00632-g2e1e921):

Add a new CPU feature, CPU_FTR_CP_USE_DCBTZ, to be added to the CPUs that
benefit
from having dcbt and dcbz instructions used in copy_4K_page(). So far Cell,
PPC970
and Power4 benefit.
This way all the other 64bit powerpc chips will have the whole prefetching loop
nop'ed out.

The fix is to defer phy init until netdevice is registered / initialized.
I think it's better instead to take the dev_mc_add() statement
out of emac_configure().
I looked yesterday into that code and I saw that dev_mc_add() was called

I just mentioned this to Ben H. on IRC and promised I would report it

The first loop over lmb.memory in this function interprets the
memory_limit as a raw size limit, and that's fine so far.
But the second loop over lmb.reserved interprets this value
instead as an address limit.

Something in a function signature called __attribute_used__ would
