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.
