The file Documentation/powerpc/ultravisor.rst contains:
Only valid value(s) in ``flags`` are:
* H_PAGE_IN_SHARED which indicates that the page is to be shared
with the Ultravisor.
* H_PAGE_IN_NONSHARED indicates that the UV is not anymore

Protected Execution Facility (PEF) is an architectural change for
POWER 9 that enables Secure Virtual Machines (SVMs). When enabled,
PEF adds a new higher privileged mode, called Ultravisor mode, to POWER
architecture. Along with the new mode there is new firmware

POWER9 processor includes support for Protected Execution Facility (PEF).
Attached documentation provides an overview of PEF and defines the API
for various interfaces that must be implemented in the Ultravisor
firmware as well as in the KVM Hypervisor.

Which POWER9? Please be more precise.
It's public knowledge that some versions of Power9 don't have PEF (or
have it broken / fused off).
