ppc patch queue for 2016-06-23

Currently outstanding patches for spapr, target-ppc and related
devices.  This batch has:
    * Significant new progress towards full support for hypervisor
      mode
    * Assorted bugfixes
    * Some preliminary patches towards dynamic DMA window support

The last involves a change to memory.c, which Paolo has said I can
take through this tree.

Signed-off-by: NPeter Maydell <peter.maydell@linaro.org>

On powerpc, we must only signal huge page support to the guest if
all memory areas are capable of supporting huge pages. The commit
2d103aae ("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
interrupt for illegal instructions and *some* type of SPR accesses.

Also the code was always generating inval instructions even for priv
violations due to setting the wrong flags

Finally, the checking for PR/HV was open coded everywhere.

This reworks it all, using little helper macros for checking, and
adding the HV interrupt (which gets converted back to program check
in the slow path of excp_helper.c on CPUs that don't want it).

Under some circumstances, we need to direct ISI and DSI interrupts
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.

This reworks emulation of the various "rfi" variants. I removed
some masking bits that I couldn't make sense of, the only bit that
I am aware we should mask here is POW, the CPU's MSR mask should
take care of the rest.

This also fixes some problems when running 32-bit userspace under
a 64-bit kernel.

This patch broke 32bit OpenBIOS when run under a 970 cpu. A fix was

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.

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
