I pulled the latest linuxppc_2_4_devel, ported gemini to it, and ran
an overnight test with:

NFS mounted root filesystem
while (true) do make clean; make -j8 zImage; done
crashme +2000 666 100 8:00:00 2
Flood ping in and out

On a dual 7410 Gemini with 1 GB RAM.  Used all but 70MB of memory.  No
hangs.

The weird thing is that crashme was supposed to run for 8 hours but
it's been running for over 14 hours now.  Any ideas?

Also, I don't think this was a particularly good test of highmem since
I don't think many bounce buffers were used, or that the kernel had
much reason to map/unmap many highmem pages.  Unfortunately, my SCSI
controller isn't working quite right and I can't test with a hard disk
as a result.  Any ideas for stressing the system harder?
