It still fails for me:

I wonder if you are using the 'block' branch, not just the master
branch? It seems to apply perfectly there, but that is just the same as
Linus' tree. So when you have cloned the block git repo, there are a
number of branches you can work against. The main branch with current
changes is the 'block' branch, that is what you want to be making
patches against.

I'll be away for the entire next week, so no rush on my end.
