Hmm.  I hit "Attach" in Thunderbird.  Viewing the message shows the
patch inline with the message for me.  I wasn't aware I needed to do
something for that.  (Any help here is appreciated.. I'm sure I can't
just copy-paste the diff because Thunderbird likes to wrap long lines
PHYSICALLY)

So I replaced TASK_UNMAPPED_BASE somewhere where it needs to be
TASK_UNMAPPED_BASE?

Function?  get_unmapped_area() and arch_get_unmapped_area()?

    wasted on re-inventing the wheel when there are so many fascinating
    new problems waiting out there.
