bbd55fe16f Merge and commit patch.apic-zwane from CVS patches directory. 
the patch release notes by Zwane:

o Define symbols for constants like
o APIC arbitration
o Processor priority
o Various interrupt delivery fixes
o Focus processor checking
o ExtINT delivery

I need to release this now so that i don't fall too far behind CVS, when
it was part of the bochs-smp patch it could boot 2.4.18 4way. Apologies
for the whitespace changes.


Also remove patch.apic-ppr-zwane patch because it already included in
patch.apic-zwane.

I hope it will help to boot x86-64 or cmp systems required missed APIC
features !
