This new one doesn't have all the Motorola-specific registers.
The old one should be deprecated and removed with the 'prep' machine.

ppc patch queue 2016-09-23

This pull request supersedes ppc-for-2.8-20160922. There was a clang
build error in that, and I've also added one extra patch in the new pull.

Included in this set of ppc and spapr patches are:
* TCG implementations for more POWER9 instructions
* Some preliminary XICS fixes in preparataion for the pnv machine type
* A significant ADB (Macintosh kbd/mouse) cleanup
* Some conversions to use trace instead of debug macros
* Fixes to correctly handle global TLB flush synchronization in
TCG. This is already a bug, but it will have much more impact
when we get MTTCG
* Add more qtest testcases for Power
* Some MAINTAINERS updates
* Assorted bugfixes
* Add the basics of NUMA associativity to the spapr PCI host bridge

This touches some test files and monitor.c which are technically
outside the ppc code, but coming through this tree because the changes
are primarily of interest to ppc.

ppc patch queue for 2016-07-05

Here's the current ppc, sPAPR and related drivers patch queue.

* The big addition is dynamic DMA window support (this includes some
core VFIO changes)
* There are also several fixes to the MMU emulation for bugs
introduced with the HV mode patches
* Several other bugfixes and cleanups

Changes in v2:
I messed up and forgot to make a fix in the last patch which BenH
pointed out (introduced by my rebasing). That's fixed in this
version, and I'm replacing the tag in place with the revised
version.

spapr_pci/spapr_pci_vfio: Support Dynamic DMA Windows (DDW)

This adds support for Dynamic DMA Windows (DDW) option defined by

T

spapr_pci/spapr_pci_vfio: Support Dynamic DMA Windows (DDW)

This adds support for Dynamic DMA Windows (DDW) option defined by
the SPAPR specification which allows to have additional DMA window(s)

The "ddw" property is enabled by default on a PHB but for compatibility
the pseries-2.6 machine and older disable it.
This also creates a single DMA window for the older machines to
maintain backward migration.

This implements DDW for PHB with emulated and VFIO devices. The host
kernel support is required. The advertised IOMMU page sizes are 4K and
64K; 16M pages are supported but not advertised by default, in order to
enable them, the user has to specify "pgsz" property for PHB and
enable huge pages for RAM.

The existing linux guests try creating one additional huge DMA window
with 64K or 16MB pages and map the entire guest RAM to. If succeeded,
the guest switches to dma_direct_ops and never calls TCE hypercalls
(H_PUT_TCE,...) again. This enables VFIO devices to use the entire RAM
and not waste time on map/unmap later. This adds a "dma64_win_addr"
property which is a bus address for the 64bit window and by default
set to 0x800.0000.0000.0000 as this is what the modern POWER8 hardware
uses and this allows having emulated and VFIO devices on the same bus.

This adds 4 RTAS handlers:
* ibm,query-pe-dma-window
* ibm,create-pe-dma-window
* ibm,remove-pe-dma-window
* ibm,reset-pe-dma-window
These are registered from type_init() callback.

These RTAS handlers are implemented in a separate file to avoid polluting
spapr_iommu.c with PCI.

This changes sPAPRPHBState::dma_liobn to an array to allow 2 LIOBNs
and updates all references to dma_liobn. However this does not add
64bit LIOBN to the migration stream as in fact even 32bit LIOBN is
rather pointless there (as it is a PHB property and the management
software can/should pass LIOBNs via CLI) but we keep it for the backward
migration support.
