kvm/powerpc: Add new ioctl to retreive server MMU infos
This is necessary for qemu to be able to pass the right information to the guest, such as the supported page sizes and corresponding encodings in the SLB and hash table, which can vary depending on the processor type, the type of KVM used (PR vs HV) and the version of KVM Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> [agraf: fix compilation on hv, adjust for newer ioctl numbers] Signed-off-by: Alexander Graf <agraf@suse.de>
