But dont see applicability of a 'fixes' > > tag to this patch > > I agree, we need not use a fixes tag then. So, we shall mark this > with v6.10 tag then. > > Cc: stable@vger.kernel.org # v6.10+ Please note that I have marked the patch for stable v6.13+ as the KVM support for Power11 was added via 96e266e3bcd6 ("KVM: PPC: Book3S HV: Add Power11 capability support for Nested PAPR guests"). Also, this commit had introduced CPU_FTR_P11_PVR on which the compat PVR check in the patch is based on. Thanks, Amit
