FYI, this kernel has issues.  It will boot up, but I don't have
networking, and even rebooting doesn't succeed.  I'm looking into it.

A bisect lands on: eventfd: switch to ->poll_mask.  That's not super
helpful, though.  I did run the ltp eventfd2 tests, and they all pass.

FWIW: https://git.gnome.org/browse/glib/commit/?id=3904c8761a60dbadbdfaf98fe23ff19cbdcc4a9a

Since that a lot of userspace (including NetworkManager) uses eventfd. I haven't
tried this patchset myself but I'd look at what the GLib mainloop is doing.
