Currently only single TCE entry per request is supported (H_PUT_TCE).
However PAPR+ specification allows multiple entry requests such as
H_PUT_TCE_INDIRECT and H_STUFF_TCE. Having less transitions to the host
kernel via ioctls, support of these calls can accelerate IOMMU operations.
This implements H_STUFF_TCE and H_PUT_TCE_INDIRECT.

This allows guests to have a different timebase origin from the host.
This is needed for migration, where a guest can migrate from one host
to another and the two hosts might have a different timebase origin.
However, the timebase seen by the guest must not go backwards, and
should go forwards only by a small amount corresponding to the time
taken for the migration.
This is only supported for recent POWER hardware which has the TBU40
(timebase upper 40 bits) register. That includes POWER6, 7, 8 but not
970.
This adds kvm_access_one_reg() to access a special register which is not
in env->spr. This requires kvm_set_one_reg/kvm_get_one_reg patch.
The feature must be present in the host kernel.
This bumps vmstate_spapr::version_id and enables new vmstate_ppc_timebase
only for it. Since the vmstate_spapr::minimum_version_id remains
unchanged, migration from older QEMU is supported but without
vmstate_ppc_timebase.

At the moment generic version-less CPUs are supported via hardcoded aliases.
For example, POWER7 is an alias for POWER7_v2.1. So when QEMU is started
with -cpu POWER7, the POWER7_v2.1 class instance is created.
This approach works for TCG and KVMs other than HV KVM. HV KVM cannot emulate
PVR value so the guest always sees the real PVR. HV KVM will not allow setting
PVR other that the host PVR because of that (the kernel patch for it is on
its way). So in most cases it is impossible to run QEMU with -cpu POWER7
unless the host PVR is exactly the same as the one from the alias (which
is now POWER7_v2.3). It was decided that under HV KVM QEMU should use
-cpu host.
Using "host" CPU type creates a problem for management tools such as libvirt
because they want to know in advance if the destination guest can possibly
run on the destination. Since the "host" type is really not a type and will
always work with any KVM, there is no way for libvirt to know if the migration
will success.
This registers additional CPU class derived from the host CPU family.
The name for it is taken from @desc field of the CPU family class.

Now that we have a CPU object with a reset method, it is better to
keep the KVM reset close to the CPU reset. Using qemu_register_reset
as we do now keeps them far apart.
With this patch, PPC no longer calls the kvm_arch_ function, so
it can get removed there. Other arches call it from their CPU
reset handler, and the function gets an ARMCPU/X86CPU/S390CPU.
Note that ARM- and s390-specific functions are called kvm_arm_*
and kvm_s390_*, while x86-specific functions are called kvm_arch_*.
That follows the convention used by the different architectures.

Normally CPUState::cpu_index is used to pick the right CPU for various
operations. However default consecutive numbering does not always work
for POWERPC.
These indexes are reflected in /proc/device-tree/cpus/PowerPC,POWER7@XX
and used to call KVM VCPU's ioctls. In order to achieve this,
kvmppc_fixup_cpu() was introduced. Roughly speaking, it multiplies
cpu_index by the number of threads per core.
This approach has disadvantages such as:
1. NUMA configuration stays broken after the fixup;
2. CPU-targeted commands from the QEMU Monitor do not work properly as
CPU indexes have been fixed and there is no clear way for the user to
know what the new CPU indexes are.
This introduces a @cpu_dt_id field in the CPUPPCState struct which
is initialized from @cpu_index by default and can be fixed later
to meet the device tree requirements.
This adds an API to handle @cpu_dt_id.
This removes kvmppc_fixup_cpu() as it is not more needed, @cpu_dt_id
is calculated in ppc_cpu_realize().
This will be used later in machine code.

PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache. We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).
We were also missing some of the required cache properties. This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases). We also
add the [id]-cache-size properties.
Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs. The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against. In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the

For the pseries machine, we need to advertise to the guest the size of its
RMA - that is the amount of memory it can access with the MMU off. For HV
KVM, this is constrained by the hardware limitations on the virtual RMA of
one hash PTE per PTE group in the hash page table. We already had code to
calculate this, but it was assuming the VRMA page size was the same as the
(host) backing page size for guest RAM.
In the case of a host kernel configured for 64k base page size, but running
on hardware (or firmware) which only allows 4k pages, the hose will do all
its allocations with a 64k page size, but still use 4k hardware pages for
actual mappings. Usually that's transparent to things running under the
host, but in the case of the maximum VRMA size it's not.
This patch refines the RMA size calculation to instead use the largest
available hardware page size (as reported by the SMMU_INFO call) which is
less than or equal to the backing page size. This now gives the correct
RMA size in all cases I've tested.

This patch makes a quick and dirty fix, by removing the CONFIG_PSERIES
dependency, replacing it with TARGET_PPC64 (since removing it entirely
leads to type mismatch errors). Technically this breaks the build when
configured with --disable-fdt, since that disables CONFIG_PSERIES on
TARGET_PPC64. However, it turns out the build was already broken in that
