1) Double spin lock bug in sunhv serial driver, from Dan Carpenter.
2) Use correct RSS estimate when determining whether to grow the
huge TSB or not, from Mike Kravetz.
3) Don't use full three level page tables for hugepages, PMD level is
sufficient. From Nitin Gupta.
4) Mask out extraneous bits from TSB_TAG_ACCESS register, we only want
the address bits.
Please pull, thanks a lot.
