The fence stealing code is broken wrt runtime pm.

The command parser duplicated dead code, the whole shadow copy needs to
be rewritten from scratch to remove the duplicated bugs.

VMA insertion is incorrect and will cause random corruption (cut'n'paste
bugs for the win).

VMA pinning is broken and will cause corruption on memory pressure, or
worse allow exploitation of a read/write to reallocated system pages.
