Hm, these bits should be factored out in a cleaner fashion - by adding helper
|
|
functions, etc. The x2apic code's integration into the lapic code was done in a
|
|
pretty ugly fashion so it's not your fault - but if we want to reintroduce UP-IOAPIC
|
|
we need to do it cleanly.
|
|
|
|
Do you still want to do it? :-)

Thanks,
