Yeah, it's not that we _can't_ pull it in, it's just that we either need to
merge in -rc5 manually first, or otherwise manually verify diffstat since
it'd otherwise cover the full delta.

My request for people to not always eagerly pick up latest -rc as base for
their branches is new for this release cycle, mostly to see how well it works
out. It would keep the history of our arm-soc changes somewhat cleaner than if
we have new -rcs "anchor in" on the graph in multiple locations like we
sometimes do now. But it might just be annoying for everyone to deal with
complying too, so we'll see how it goes.
