I think we are sorted (see the later patch to auto size the per cpu
area).  But you should be ok with current -mm if you compile for 64 or
fewer cpus.

Yep it looks like the config file I tote around on this box has
CONFIG_NR_CPUS=128. I thought this this was the default NR_CPUS but it
is not.

Thanks,
 Keith
