[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. Signed-off-by: David S. Miller <davem@davemloft.net>
