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

Pull sparc fixes from David Miller:
 "Please pull to get these sparc AES/DES/CAMELLIA crypto bug fixes as
  well as an addition of a pte_accessible() define for sparc64 and a
  hugetlb fix from Dave Kleikamp."

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc:
  sparc64: Set CRYPTO_TFM_REQ_MAY_SLEEP consistently in CAMELLIA code.
  sparc64: Set CRYPTO_TFM_REQ_MAY_SLEEP consistently in DES code.
  sparc64: Fix ECB looping constructs in AES code.
  sparc64: Set CRYPTO_TFM_REQ_MAY_SLEEP consistently in AES code.
  sparc64: Fix AES ctr mode block size.
  sparc64: Fix unrolled AES 256-bit key loops.
  sparc64: Define pte_accessible()
  sparc: huge_ptep_set_* functions need to call set_huge_pte_at()
