[Yinghai Lu]

please check some amd opteron related mmconf and numa patches

Greg, any deep objections against these patches? (other than that they 
need a good amount of testing) I personally think that the more 
independent the kernel is of the whims of the BIOS, the better ...

No objection from me, other than they need a LOT of testing.  Oh, and
the networking patch is still wrong, and the poster has been told this
numerous times, which makes me wonder how well the pci bridge patch was
tested...

thanks,

ok - have queued it up for v2.6.26. Note: Andrew might get grumpy when 
your PCI tree starts changing nearby places in arch/x86/pci again and it 
clashes with these changes in x86.git - in that case please pick up the 
full lot from x86.git#testing and carry it in the PCI tree. (or, 
alternatively, send me any trivial, arch/x86-only PCI bits to 
x86.git#testing so that we can keep it and test it all in a single place 
- whichever approach is more convenient to you)

i think the optimization should be more correct now than in the past, 
its purpose and dependencies just have not been communicated fully. 
We'll get there eventually :-)

Hopefully we can soon start feeding these more problematic trees into linux-next
and yes, Stephen will need some more thought/support from his upstreams to make
that viable.

btw., the correct metric would be "real user-side regressions per 
commit" (maybe real regressions per line of code changed), not "number 
of commits". With the latter metric, x86.git is "problematic". For the 
former, it's much less so ;-)

i.e. you should punish buggy trees that affect real testers out there, 
not high-flux trees that by virtue of their flux cause more integration 
work.

ACK for my parts (stuff associated with PCI domain support on x86)
