Hi Arnd,

Please pull the following CPU mapping patches for 3.2. Russell has merged
the core changes into his for-next branch, so this pull is based against
that (following the merging discussion we had previously). I can rebase
onto next/master if you prefer.

Cheers,

Will

No, please don't use that as a base.  This commit is likely to vanish 
the next time RMK reconstructs his for-next branch.  You should instead 
base those patches on the actual branch tip that RMK merged from you.

D'oh, I thought this might happen. The problem I have is that my core
patches depend on one from Vincent Guittot ("ARM: 7011/1: Add ARM cpu
topology definition"), so I ended up sending my changes via Russell's patch
system.

How about I cherry pick Vincent's patch and my core changes out of next and
use that as a base (on top of -rc4)?

I would instead suggest that you simply use commit c2b9ab71c6 as your 
base.  It is more likely to remain stable, unlike the top commit in the 
for-next branch.

Cherry-picking needed commits would work, but they would end up being 
duplicated in two different branches in the final Git history.  Git can 
cope with that of course, but this is usually something we try to avoid 
as this could create some confusion for people.
