[Qemu-ppc] [QEMU-PPC] [PATCH V2 0/3] ppc/spapr: Add support for nested kvm-hv

[Suraj Jitindar Singh]

This patch series adds the qemu support for running nested kvm-hv on a
POWER9 platform with appropriate hypervisor support and migration of
these guests.
That is, the ability to run kvm-hv guests as guests of an operating system
which is itself a kvm-hv guest.

The host (L0 hypervisor) and level 1 guest (L1 guest hypervisor) require
the following patch series:
KVM: PPC: Book3S HV: Nested HV virtualization

And this patch series in the qemu instance running on the L0 hypervisor.

Patch series based on: ppc-for-3.1

Still waiting for the cap number and one reg id to be confirmed in linux.

Changes RFC -> V2:
- Split header changes into separate patch
- Reword error messages when enabling nested-hv with kvm

Suraj Jitindar Singh (3):
  target/ppc: Update linux-headers for v4.19-rc7
  target/ppc: Add one reg id for ptcr
  ppc/spapr_caps: Add SPAPR_CAP_NESTED_KVM_HV
