The point is, there is no "locally".

Do you mean locally on my machine? That's actually *different* from the 
locally on the public machines, and no, I wouldn't give you that 
information anyway (since that information would include the mistakes that 
I fixed up ;)

And in fact, even on the public machines, the "locally" would be different 
depending on things like mirroring delays, although that is currently 
hidden by the fact that kernel.org uses rsync for mirroring rather than 
using git natively.

So in theory, we could pick one particular public kernel.org machine, and 
use the times as _that_ machine sees it, but the fact is, that isn't how 
git works. No normal git command will ever show you such a senseless 
ordering.

I suspect that the closest you could get to what you want would be to 
actually run git-cvsserver on kernel.org to export the git data as "CVS" 
data, and then you could use a CVS client that gets a linearized model of 
history. That is, afaik, the only way to give you what you want.

And quite frankly, I'd never ask the kernel.org maintainers to do 
something that perverse. You could ask them, and maybe they would do so 
out of some really perverse self-destructive death-wish, but quite 
frankly, you'd probably be better off setting up such a git->CVS gateway 
on some local machine yourself.
