[parisc-linux] LMBench on SMP A500

Hello Parisc-linux hackers,

I ran the lmbench mark sweet against an dual-processor A500.  I have
attached the results of the benchmark for people to review.

I am not convinced of the validity of the benchmark because the
following message repeatedly showed up in dmesg:


do_page_fault() pid=22449 command='lat_sig' type=15 address=0x40019000
vm_start = 0x40019000, vm_end = 0x4001a000

but I wanted to throw the results out for discussion.

Thanks,
