Yes, I tried a compilation with MULTIQUAD on.

The "very recent" might be that I'm talking about -ac (look at the

First of all:
I noticed this problem while doing a compile-only test, I have no real
knowledge of the code.

In 2.4.20-pre the following change was made in several places:
clustered_apic_mode -> (clustered_apic_mode == CLUSTERED_APIC_NUMAQ)

In 2.4.20-pre-ac they were changed again, this time
(clustered_apic_mode == CLUSTERED_APIC_NUMAQ) -> clustered_apic_logical

According to grep the occurence of CLUSTERED_APIC_NUMAQ my patch changes
was the last one _in the whole kernel sources of 2.4.20-rc4-ac1_.

It might be that my patch is wrong but there's undoubtable something
that needs to be fixed.
