Can you please review this w.r.t 64bit bo
Current swap encoding in pte can't support large pfns
above 4TB. Change the swap encoding such that we put
the swap type in the PTE bits. Also add build checks
to make sure we don't overlap with HPTEFLAGS.

We'll want to build the opal-prd daemon with the prd headers, so include
this in the uapi headers list.

There is a RCPM (Run Control/Power Management) in Freescale QorIQ
series processors. The device performs tasks associated with device
run control and power management.
The driver implements some features: mask/unmask irq, enter/exit low
power states, freeze time base, etc.
