spapr: Add SPAPR_CAP_AIL_MODE_3 for AIL mode 3 support for H_SET_MODE hcall

The behaviour of the Address Translation Mode on Interrupt resource is
not consistently supported by all CPU versions or all KVM versions: KVM
HV does not support mode 2, and does not support mode 3 on POWER7 or
early POWER9 processesors. KVM PR only supports mode 0. TCG supports all
modes (0, 2, 3) on CPUs with support for the corresonding LPCR[AIL] mode.
This leads to inconsistencies in guest behaviour and could cause problems
migrating guests.

This was not noticable for Linux guests for a long time because the
kernel only uses modes 0 and 3, and it used to consider AIL-3 to be
advisory in that it would always keep the AIL-0 vectors around, so it
did not matter whether or not interrupts were delivered according to
the AIL mode. Recent Linux guests depend on AIL mode 3 working as
specified in order to support the SCV facility interrupt. If AIL-3 can
not be provided, then H_SET_MODE must return an error to Linux so it can
disable the SCV facility (failure to do so can lead to userspace being
able to crash the guest kernel).

Add the ail-mode-3 capability to specify that AIL-3 is supported. AIL-0
is implied as the baseline, and AIL-2 is no longer supported by spapr.
AIL-2 is not known to be used by any software, but support in TCG could
be restored with an ail-mode-2 capability quite easily if a regression
is reported.

Modify the H_SET_MODE Address Translation Mode on Interrupt resource
handler to check capabilities and correctly return error if not
supported.

KVM has a cap to advertise support for AIL-3.

Merge remote-tracking branch 'remotes/dg-gitlab/tags/cgs-pull-request' into staging

Generalize memory encryption models

A number of hardware platforms are implementing mechanisms whereby the
hypervisor does not have unfettered access to guest memory, in order
to mitigate the security impact of a compromised hypervisor.

AMD's SEV implements this with in-cpu memory encryption, and Intel has
its own memory encryption mechanism. POWER has an upcoming mechanism
to accomplish this in a different way, using a new memory protection
level plus a small trusted ultravisor. s390 also has a protected
execution environment.

The current code (committed or draft) for these features has each
platform's version configured entirely differently. That doesn't seem
ideal for users, or particularly for management layers.

AMD SEV introduces a notionally generic machine option
"machine-encryption", but it doesn't actually cover any cases other
than SEV.

This series is a proposal to at least partially unify configuration
for these mechanisms, by renaming and generalizing AMD's
"memory-encryption" property. It is replaced by a
"confidential-guest-support" property pointing to a platform specific
object which configures and manages the specific details.

Note to Ram Pai: the documentation I've included for PEF is very
minimal. If you could send a patch expanding on that, it would be
very helpful.

Changes since v8:
* Rebase
* Fixed some cosmetic typos
Changes since v7:
* Tweaked and clarified meaning of the 'ready' flag
* Polished the interface to the PEF internals
* Shifted initialization for s390 PV later (I hope I've finally got
this after apply_cpu_model() where it needs to be)
Changes since v6:
* Moved to using OBJECT_DECLARE_TYPE and OBJECT_DEFINE_TYPE macros
* Assorted minor fixes
Changes since v5:
* Renamed from "securable guest memory" to "confidential guest
support"
* Simpler reworking of x86 boot time flash encryption
* Added a bunch of documentation
* Fixed some compile errors on POWER
Changes since v4:
* Renamed from "host trust limitation" to "securable guest memory",
which I think is marginally more descriptive
* Re-organized initialization, because the previous model called at
kvm_init didn't work for s390
* Assorted fixes to the s390 implementation; rudimentary testing
(gitlab CI) only
Changes since v3:
* Rebased
* Added first cut at handling of s390 protected virtualization
Changes since RFCv2:
* Rebased
* Removed preliminary SEV cleanups (they've been merged)
* Changed name to "host trust limitation"
* Added migration blocker to the PEF code (based on SEV's version)
Changes since RFCv1:

spapr: Add PEF based confidential guest support

Some upcoming POWER machines have a system called PEF (Protected
Execution Facility) which uses a small ultravisor to allow guests to
run in a way that they can't be eavesdropped by the hypervisor. The
effect is roughly similar to AMD SEV, although the mechanisms are
quite different.

Most of the work of this is done between the guest, KVM and the
ultravisor, with little need for involvement by qemu. However qemu
does need to tell KVM to allow secure VMs.

Because the availability of secure mode is a guest visible difference
which depends on having the right hardware and firmware, we don't
enable this by default. In order to run a secure guest you need to
create a "pef-guest" object and set the confidential-guest-support
property to point to it.

Note that this just *allows* secure guests, the architecture of PEF is
such that the guest still needs to talk to the ultravisor to enter
secure mode. Qemu has no direct way of knowing if the guest is in
secure mode, and certainly can't know until well after machine
creation time.

To start a PEF-capable guest, use the command line options:
-object pef-guest,id=pef0 -machine confidential-guest-support=pef0

target/ppc: Fix kvmppc_load_htab_chunk() error reporting

If kvmppc_load_htab_chunk() fails, its return value is propagated up
to vmstate_load(). It should thus be a negative errno, not -1 (which
maps to EPERM and would lure the user into thinking that the problem
is necessarily related to a lack of privilege).

Return the error reported by KVM or ENOSPC in case of short write.
While here, propagate the error message through an @errp argument
and have the caller to print it with error_report_err() instead
of relying on fprintf().

pseries: fix kvmppc_set_fwnmi()

QEMU issues the ioctl(KVM_CAP_PPC_FWNMI) on the first vCPU.

If the first vCPU is currently running, the vCPU mutex is held
and the ioctl() cannot be done and waits until the mutex is released.
This never happens and the VM is stuck.

To avoid this deadlock, issue the ioctl on the same vCPU doing the
RTAS call.

The problem can be reproduced by booting a guest with several vCPUs
(the probability to have the problem is (n - 1) / n, n = # of CPUs),
and then by triggering a kernel crash with "echo c >/proc/sysrq-trigger".

On the reboot, the kernel hangs after:

spapr,ppc: Simplify signature of kvmppc_rma_size()

This function calculates the maximum size of the RMA as implied by the
host's page size of structure of the VRMA (there are a number of other
constraints on the RMA size which will supersede this one in many
circumstances).

The current interface takes the current RMA size estimate, and clamps it
to the VRMA derived size. The only current caller passes in an arguably
wrong value (it will match the current RMA estimate in some but not all
cases).

We want to fix that, but for now just keep concerns separated by having the
KVM helper function just return the VRMA derived limit, and let the caller
combine it with other constraints. We call the new function
kvmppc_vrma_limit() to more clearly indicate its limited responsibility.

The helper should only ever be called in the KVM enabled case, so replace
its !CONFIG_KVM stub with an assert() rather than a dummy value.
