[Qemu-ppc] [QEMU-PPC] [PATCH V4 00/11] target/ppc: Implement POWER9 pseries tcg legacy support

[Suraj Jitindar Singh]

This is V4 of the patch series to implement tcg emulation support for a
POWER9 cpu model for the pseries machine type running a legacy kernel.
That is a kernel which doesn't use the new radix mmu mode or the new hash
mmu mode with segment tables.

To use a POWER9 cpu provide the command line option "-cpu POWER9".

This series attempts to avoid precluding KVM-HV support for the POWER9
cpu model but doesn't attempt to support KVM-PR or the powernv machine
for the POWER9 cpu model as these aren't currently supported or
implemented and further code changes will be required in the event these
are implemented.

This series is based on the hpt-cleanup branch.

The changes from V3 are as follows:

 - Add a flag POWERPC_MMU_V3 to mmu_model and check this where appropriate
 - Add LPCR_HR define
 - Remove function ppc_hash64_set_sdr1() and split this into new patch
 - Add file mmu-book3s-v3.c to handle new ISAV3 generic mmu code
 - Rebase on hpt-cleanup branch
