Fedora has something similar:
Patch02: git-linus.diff
ApplyOptionalPatch git-linus.diff
This gets applied early, before any fedora patches, and since it's
really meant for applying an upstream git snapshot it gets applied
even when building a vanilla upstream kernel.
I use it all the time for testing -stable updates.
