Merge branch 'for-3.20' of git://git./linux/kernel/git/tj/libata

Pull libata changes from Tejun Heo:
 "Mostly driver-specific changes.  Nothing too noteworthy.

  This pull request contains three merges from for-3.19-fixes.  The
  first two are to pull ahci_xgene and sata_dwc_460ex fix commits which
  are depended upon by later changes.  The last one is to pull in a fix
  patch which missed the v3.19-rc window"
