Hi Sam,

Our definition of "cherry-pick" is a bit different from the one used
by git. For us to consider a patch to be "cherry picked" from a given
SHA1, when you generate a patch from the original tree (e.g. Linus'
tree) using "git format-patch" we need to be able to apply the
resulting patch to the target repo with "git am". Sometimes there is
only a small difference in the context and a patch can be applied
using "git am -C2", in that case the submitter just needs to state in
the cover letter that "-C2" is needed.

If that doesn't work, and even if we need to do a "git cherry-pick"
first on the target repo and generate the patch from there, then
it's consider to be "backported from".
