Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  n2_crypto: Attach on Niagara-T3.
  n2rng: Attach on Niagara-T3.
  sparc: Detect and handle UltraSPARC-T3 cpu types.
  sparc: Don't do expensive hypervisor PCR write unless necessary.
  sparc: Add T3 sun4v cpu type and hypervisor group defines.
  sparc: Don't leave sparc_pmu_type NULL on sun4v.
