There are some conflicts with misfit on 4.20-rc1 (nothing major, just that
misfit logic appeared where the stealing logic wants to land), and git
gets lost after a few conflict resolutions.

It's fine for testing on 4.19 - I just apply the misfit series then merge
a branch with the steal patches to fix it all at once - but it makes
playing around with 4.20-rc* more tedious.
