QEMU will currently automatically make use of the KVM_SEV_INIT2 API for

However, the older interfaces will silently avoid sync'ing FPU/XSAVE

This optional parameter for query-cpu-model-expansion enables CPU
model features flagged as deprecated to appear in the resulting
list of properties.
This commit does not add support beyond adding a new argument
to the query. All queries with this option present will result
in an error claiming th
The current implementation of query-cpu-model-expansion is lacking a way to
conditionally retrieve CPU models with properties (i.e. features) that are
flagged as deprecated set to disabled. To remedy this, a new optional boolean
"disable-deprecated-feats" argument has been added to the query.

Retain a list of deprecated features disjoint from any particular
CPU model. When a query-cpu-model-expansion is provided with the
"disable-deprecated-feats" option set, the resulting properties list
will include all deprecated features paired with false. Example:

This series does some further clean up mostly around BookE MMU to
untangle it from other MMU models. It also contains some other changes
that I've come up with while working on this. The first 3 patches are
from the last exception handling clean up series that were dropped due
to some error on CI b
The real mode handling is identical in the remaining switch cases.
Split off these common real mode cases into a separate conditional to
leave only the else branches in the switch that are different.

Unlike sc, for scv a facility unavailable interrupt must be generated
if FSCR[SCV]=0 so we can't raise the exception with nip set to next
instruction but we can move advancing nip if the FSCR check passes to
helper_scv so the exception handler does not need to change it.
[b
This function is no longer called for BookE MMU model so remove parts
related to it. This has uncovered a few may be used uninitialised
warnings that are also fixed.
