Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-4.1-20190702' into staging 

ppc patch queue 2019-07-2

Here's my next pull request for qemu-4.1.  I'm not sure if this will
squeak in just before the soft freeze, or just after.  I don't think
it really matters - most of this is bugfixes anyway.  There's some
cleanups which aren't stictly bugfixes, but which I think are safe
enough improvements to go in the soft freeze.  There's no true feature
work.

Unfortunately, I wasn't able to complete a few of my standard battery
of pre-pull tests, due to some failures that appear to also be in
master.  I'm hoping that hasn't missed anything important in here.

Highlights are:
  * A number of fixe and cleanups for the XIVE implementation
  * Cleanups to the XICS interrupt controller to fit better with the new
    XIVE code
  * Numerous fixes and improvements to TCG handling of ppc vector
    instructions
  * Remove a number of unnnecessary #ifdef CONFIG_KVM guards
  * Fix some errors in the PCI hotplug paths
  * Assorted other fixes

---------------
QEMU advertises the supported interrupt modes in the device tree
property "ibm,arch-vec-5-platform-support" in byte 23 and the OS
Selection for XIVE is indicated in the "ibm,architecture-vec-5"
property ``ibm,arch-vec-5-platform-support`` in byte 23 and the OS
Selection for XIVE is indicated in the ``ibm,architecture-vec-5``
property byte 23.
The interrupt modes supported by the machine depend on the CPU type
(POWER9 is required for XIVE) but also on the machine property
``ic-mode`` which can be set on the command line. It can take the
following values: ``xics``, ``xive``, ``dual`` and currently ``xics``
is the default but it may change in the future.
following values: ``xics``, ``xive``, and ``dual`` which is the
default mode. ``dual`` means that both modes XICS **and** XIVE are
supported and if the guest OS supports XIVE, this mode will be
selected.
The choosen interrupt mode is activated after a reconfiguration done
in a machine reset.
KVM negotiation
---------------
When the guest starts under KVM, the capabilities of the host kernel
and QEMU are also negotiated. Depending on the version of the host
kernel, KVM will advertise the XIVE capability to QEMU or not.
Nevertheless, the available interrupt modes in the machine should not
depend on the XIVE KVM capability of the host. On older kernels
without XIVE KVM support, QEMU will use the emulated XIVE device as a
fallback and on newer kernels (>=5.2), the KVM XIVE device.
As a final refinement, the user can also switch the use of the KVM
device with the machine option ``kernel_irqchip``.
