Hi,
in patch-2.4.20 'static void amd_adv_spec_cache_disable(void)' was removed
from arch/i386/kernel/setup.c.
I haven't found any patch on lkml posted that did this and it wasn't mentioned
in 2.4.20's changelog.
Can someone point to a why this was removed, maybe a different fix since the
one mentioned says "Short-term fix" or is it not needed anymore for some
reason?
Bye,
Oliver

A better fix went in. See the changes to agpgart.

The "long term" fix for it went in instead (arch/i386/mm/pageattr.c)
The kernel is careful now to not create conflicting cache attributes
for AGP and other mappings. This makes the linux kernel x86
conformant in this area. It also increases performance on
Athlon XP/MP because they can now use large pages in kernel space again.

Ah yes, indeed. I must have missed that. :)
Thanks for the quick answers everyone.
