Please don't move around large blocks of code *and* change the code in

This tests that when a process with a mapping above 512TB forks we
correctly separate the parent and child address spaces. This exercises
the bug in the context id handling fixed in the previous commit.

The performance stop status and control register (PSSCR) is used to
control the power saving facilities of the processor. This register has
various fields, some of which can be modified only in hypervisor state,
and others which can be modified in both hypervisor and priviledged
non-hypervisor stat
The ability to run nested guests under KVM means that a guest can also
act as a hypervisor for it's own nested guest. Currently
ppc_set_pmu_inuse() assumes that either FW_FEATURE_LPAR is set,
indicating a guest environment, and so sets the pmcregs_in_use flag in
the lppaca, or that it isn't set, in
The performance monitoring unit (PMU) registers are saved on guest exit
when the guest has set the pmcregs_in_use flag in its lppaca, if it
exists, or unconditionally if it doesn't. If a nested guest is being
run then the hypervisor doesn't, and in most cases can't, know if the
pmu registers are in

You need gas 2.28 or later for that though.
