KVM: PPC: Book3S PR: Enable kvmppc_get/set_one_reg_pr() for HTM registers
We need to migrate PR KVM during transaction and userspace will use
kvmppc_get_one_reg_pr()/kvmppc_set_one_reg_pr() APIs to get/set
transaction checkpoint state. This patch adds support for that.
So far, QEMU on PR KVM doesn't fully function for migration but the
savevm/loadvm can be done against a RHEL72 guest. During savevm/
loadvm procedure, the kvm ioctls will be invoked as well.
Test has been performed to savevm/loadvm for a guest running
a HTM test program:
