Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170202' into staging
ppc patch queue 2017-02-02
This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:
* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.
There are also some changes not strictly related to ppc code, but for
its benefit:
* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for
some of the new instructions.
* Revise a number of qtests and enable them for ppc
