Re: [git pull] Please pull powerpc.git merge branch

So this happens if you have "reverse merges" (ie you've pulled my
tree, or some other tree I've pulled), and there is no longer a single
clear common point that you started from. In that case, there is no
simple diff for the "what has changed since that original point", and
to get the diff for the merge you actually have to do the merge and
check the end result. git-request-pull doesn't do that, it just
assumes it's the simple case of some single common point.

That was more/less my guess. Thanks.

The fact that you haven't seen it until now just means that you've
generally done a good job at keeping your powerpc tree "clean" from
other trees, and containing only your own work. 

Heh, yeah I try to :-) In this specific case, this was a topic branch
from Bjorn which some pre-requisite patches to the generic PCI code that
Gavin did to allow us to get rid of some custom resource allocation
crap, so the "getting rid of" had a dependency on that topic branch.

Unfortunately, Bjorn had also based that branch on top of some larger
cleanup patch so I ended up pulling that as well from him, which tripped
the whole thing.

Cheers,
Ben.
