commit 707aec94c54127ebfda7d0f8455ecbb332ee49f0

x86/percpu: Force INVALID_PERCPU_AREA into the non-canonical address
region
This causes accidental uses of per_cpu() on a pcpu with an
INVALID_PERCPU_AREA
to result in a #GF for attempting to access the middle of the
non-canonical
virtual address region.
This is preferable to the current behaviour, where incorrect use of
per_cpu()
will result in an effective NULL structure dereference which has security
implication in the context of PV guests.
