Thanks Dave -- sounds good.  After all, the whole point of linux-next is
to spot these and vet out arch/merge issues before they get merged.

No matter what level of arch and config coverage I try to do, it seems
linux-next still finds a corner case that I somehow missed.

Hopefully we don't lose sight of that underlying goal and we don't
inadvertently intimidate folks from requesting their changes to be added
to linux-next.

Paul.
