Results for 3.1 testsuite on i686-pc-linux-gnu

["David G. Miller" <dave at bend dot local dot davenjudy dot org>]

Operating System is Red Hat 7.3 base but with 2.5.25 kernel, ALSA sound system.  Both seem to be working fine.

Hardware is a Tyan Tiger S2466N-4M motherbaord with 2 x AMD Athlon 1900+ MP CPUs, 1 GB memory.

Note: Please update your build advice with regard to SMP systems.  The page currently says that there is nothing to be gained by setting the -j parameter to make higher than the number of installed CPUs.  This is NOT correct.  Please see the following table of kernel build times with different values of j given to make.  Data was collected from compiles of the 2.5.25 kernel and, admittedly, aren't exact since there was generally a small tweak to the make configuration between builds.  In my opinion, the affect of these changes to the configuration should be negligible.
