i.e. numa_info[x].node_cpu -> PCMachineState.node_cpu
2. apic id -> srat entry PMX
PCMachineState.node_cpu[apic id] -> PMX value
use numa_info[x].node_cpu map directly like ARM does and do
1. numa_info[x].node_cpu -> PMX value using index
in range 0..maxcpus
and drop not necessary PCMachineState.node_cpu and related

ppc: Disable huge page support if it is not available for main RAM
On powerpc, we must only signal huge page support to the guest if
all memory areas are capable of supporting huge pages. The commit
2d103aae8765 ("fix hugepage support when using memory-backend-file")
already fixed the case when the user specified the mem-path property
for NUMA memory nodes instead of using the global "-mem-path" option.
However, there is one more case where it currently can go wrong.
When specifying additional memory DIMMs without using NUMA, e.g.
qemu-system-ppc64 -enable-kvm ... -m 1G,slots=2,maxmem=2G \
-device pc-dimm,id=dimm-mem1,memdev=mem1 -object \
memory-backend-file,policy=default,mem-path=/...,size=1G,id=mem1
the code in getrampagesize() currently assumes that huge pages
are possible since they are enabled for the mem1 object. But
since the main RAM is not backed by a huge page filesystem,
the guest Linux kernel then crashes very quickly after being
started. So in case the we've got "normal" memory without NUMA
and without the global "-mem-path" option, we must not announce
huge pages to the guest. Since this is likely a mis-configuration
by the user, also spill out a message in this case.

Recent server processors use the Hypervisor Emulation Assistance

Also the code was always generating inval instructions even for priv

ppc: Fix generation if ISI/DSI vs. HV mode

at the hypervisor, turning them into HISI/HDSI, and using different
SPRs (HDSISR and HDAR) depending on the combination of MSR_DR and
the corresponding VPM bits in LPCR.
This moves part of the code into helpers that are fixed to select
the right exception type and registers. On pre-P7 processors, LPCR
is 0 which provides the old behaviour of directing the interrupts
at the supervisor.

memory: Add reporting of supported page sizes
Every IOMMU has some granularity which MemoryRegionIOMMUOps::translate
uses when translating, however this information is not available outside
the translate context for various checks.
This adds a get_min_page_size callback to MemoryRegionIOMMUOps and
a wrapper for it so IOMMU users (such as VFIO) can know the minimum
actual page size supported by an IOMMU.
As IOMMU MR represents a guest IOMMU, this uses TARGET_PAGE_SIZE
as fallback.
This removes vfio_container_granularity() and uses new helper in
memory_region_iommu_replay() when replaying IOMMU mappings on added
IOMMU memory region.

ppc: Improve emulation of THRM registers
The 75x and 74xx processors have some thermal monitoring SPRs that
some OSes such as MacOS do use. Our current "dumb" implementation
isn't good enough and will cause some versions of MacOS to hang during
boot.
This lifts an improved emulation from MacOnLinux and adapts it to
qemu, thus fixing the problem.

powerpc/mm: Update the WIMG check during H_ENTER
Support for 0 value for memeory coherence is optional and with ppc64
we can always enable memory coherence. Linux kernel did that during
the development of 4.7 kernel. But that resulted in failure in Qemu
in H_ENTER hcall due to below check. The mentioned change was reverted
in the kernel and kernel right now enable memory coherence only if
cache inhibited is not set. Nevertheless update qemu WIMG flag check
to cover the case where we enable memory coherence along with cache
inhibited flag.
In order to handle older and newer kernel version consider both Cache
inhibitted and (cache inhibitted | memory conference) as valid values
for wimg flags.
