[SPARC64]: Fix two bugs wrt. kernel 4MB TSB.
1) The TSB lookup was not using the correct hash mask.
2) It was not aligned on a boundary equal to it's size,
which is required by the sun4v Hypervisor.
wasn't having it's return value checked, and that bug will be fixed up
as well in a subsequent changeset.
