PATCH v2: https://lkml.org/lkml/2021/7/6/138
PATCH v3: https://lkml.org/lkml/2021/7/12/2799

PATCH v6: https://lkml.org/lk
Adds a generic interface to represent the energy and frequency related
PAPR attributes on the system using the new H_CALL
"H_GET_ENERGY_SCALE_INFO".
H_GET_EM_PARMS H_CALL was previously responsible for exporting this
information in the lparcfg, however the H_GET_EM_PARMS H_CALL
will be deprecated

This series still aims to stop contaminating the l2_hv structure with
bits that might have come from L1 state.
Patch 1 makes l2_hv read-only (mostly). It is now only changed when we
explicitly want to pass information to L1.
Patch 2 makes sure that L1 is not forwarded HFU interrupts when the
host
If the nested hypervisor has no access to a facility because it has
been disabled by the host, it should also not be able to see the
Hypervisor Facility Unavailable that arises from one of its guests
trying to access the facility.
This patch turns a HFU that happened in L2 into a Hypervisor Emulat
As one of the arguments of the H_ENTER_NESTED hypercall, the nested
hypervisor (L1) prepares a structure containing the values of various
hypervisor-privileged registers with which it wants the nested guest
(L2) to run. Since the nested HV runs in supervisor mode it needs the
host to write to these
