Jeff Dike expressed interest in doing it, but I don't think he has done any
of the regset work.  What's there now (in utrace-tracehook-um.patch) is
just the tracehook branch part of the work, which is enough simply to get
UML to compile and work again with CONFIG_UTRACE=n (and hence, no ptrace).

UML is different from a normal port, because it is not an architecture
itself, but is a different variant port of each other architecture.  The
regset details are already chosen for each arch, and just need to be
implemented compatibly in the UML context.

I am no great expert on git, and even less when I started with it.  The servers don't let me do much other than push heads,
so I cannot easily clean up the repository there like I clean up my own
local repositories.  The right thing would be to have a refs/heads/master
there is a symbolic ref for refs/heads/utrace-ptrace-compat.
