SubjectRe: [PATCH][POKE] Skip looking for ioapic overrides when ioapics are not present
From
Date
(Something, somewhere, chocked on that "[.34+]@schatten.dmk.lab" address
that was in the CC list, so I removed it. Invalid address? Invalid TLD?)

Seems to have the same goal as commit
678301ecadec24ff77ab310eebf8a32ccddb1850 ("x86, ioapic: Don't warn about
non-existing IOAPICs if we have none"), which got merged in the v2.6.38
cycle (authored by me, signed off by Ingo Molnar). Maybe Eric's patch is
more correct. I can't say as I was happy with the effect of my patch
(ie, make an uninteresting error disappear) and didn't investigate any
further. I have also no desire to dive into this matter again.
