booke206: fix MAS update on tlb miss
When a tlb instruction miss happen, rw is set to 0 at the bottom
of cpu_ppc_handle_mmu_fault which cause the MAS update function to miss
the SAS and TS bit in MAS6, MAS1 in booke206_update_mas_tlb_miss.
Just calling booke206_update_mas_tlb_miss with rw = 2 solve the issue.

ppc: fix double-free in cpu_post_load()
When running nested with KVM PR, ppc_set_compat() fails and QEMU crashes
because of "double free or corruption (!prev)". The crash happens because
error_report_err() has already called error_free().

target/ppc: Implement TIDR
This adds a trivial implementation of the TIDR register added in
POWER9. This isn't particularly important to qemu directly - it's
used by accelerator modules that we don't emulate.
However, since qemu isn't aware of it, its state is not synchronized
with KVM and therefore not migrated, which can be a problem.

target/ppc: Add stub implementation of the PSSCR
The PSSCR register added in POWER9 controls certain power saving mode
behaviours. Mostly, it's not relevant to TCG, however because qemu
doesn't know about it yet, it doesn't synchronize the state with KVM,
and thus it doesn't get migrated.
To fix that, this adds a minimal stub implementation of the register.
This isn't complete, even to the extent that an implementation is
possible in TCG, just enough to get migration working. We need to
come back later and at least properly filter the various fields in the
register based on privilege level.

Log Message:
-----------
spapr_drc: abort if object_property_add_child() fails
object_property_add_child() can only fail in two cases:
- the child already has a parent, which shouldn't happen since the DRC was
allocated a few lines above
- the parent already has a child with the same name, which would mean the
caller tries to create a DRC that already exists
In both case, this is a QEMU bug and we should abort.

spapr: Fix bug in h_signal_sys_reset()
The unicast case in h_signal_sys_reset() seems to be broken:
rather than selecting the target CPU, it looks like it will pick
either the first CPU or fail to find one at all.
Fix it by using the search function rather than open coding the
search.
This was found by inspection; the code appears to be unused because
the Linux kernel only uses the broadcast target.

into staging
ppc patch queue 2017-08-09
This series contains a number of bugfixes for ppc and related
machines, for the qemu-2.10.release. Some are true regressions,
others are serious enough and non-invasive enough to fix that it's
worth putting in 2.10 this late.
