Crap. Sorry about that. I did get a report last night from Josh (Cc'd)
that the above commit caused hangs during boot on a bunch of his
machines. All grub2 and all secure boot enabled, I think.

Linus, what are the particulars of your Sony machine? Are you running
with secure boot on? Is is a regular grub2/Fedora machine?

Reverting this is obviously the way to go, but it would be useful to
diagnose this failure some more - there's clearly a gap in my testing.
