Remember the kernel build times that I sent out a while back:
SMP+DISCONTIG
-------------
781.20user 203.99system 5:05.95elapsed 322%CPU (0avgtext+0avgdata
0maxresident)k0inputs+0outputs (508064major+1830860minor)pagefaults 0swaps
After the cache flushing optimizations, this came down to:
SMP+DISCONTIG
-------------
699.72user 132.15system 4:48.63elapsed 288%CPU (0avgtext+0avgdata
0maxresident)k0inputs+0outputs (458609major+1632642minor)pagefaults 0swaps
And after the recent tlbflush optimizations:

0inputs+0outputs (508064major+1831879minor)pagefaults 0swaps
I am still trying to figure out the DISCONTIGMEM problem, but at least
it seems that on specific memory configurations, not ignoring the 128Mb
memory on the 7th bank seems to create problems. Go figure.
