I just patched my 2.4.20rc2 kernel. Now, it reports
512K cache for my 2 Tualatin 1.26 GHz CPUs.
'time make -j4 bzImage' went down from 3:30 to 3:04.
Not too bad.
Cheers,
Mathias

That is quite an impressive gain. The patch I sent Marcelo which
also fixes up a problem with some tualatins and adds P4 trace cache
support is at..
ftp.kernel.org/pub/linux/kernel/people/davej/patches/2.4/2.4.20/descriptors.diff
As you have tualatins can you try with the above patch and make sure
theres no regressions there ?
