Additional info:
0886.lwoodman.x86-64-clust-apic.patch

Comment 2 Jeff Burke 2007-02-03 13:52:59 UTC

Patch submitted to internal mailing list for development ACKs.

This is by no means a critical item. It just cleans up the code base and puts
x86_64 inline with i386. Also reduces the overall CPU debug messages being sent
to /var/log/messages.
