Merge branch 'for-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata

Pull libata updates from Tejun Heo:
 "A lot of activities on libata side this time.

   - A lot of changes around ahci.  Various embedded platforms are
     implementing ahci controllers.  Some were built atop ahci_platform,
     others were doing their own things.  Hans made some structural
     changes to libahci and librarized ahci_platform so that ahci
     platform drivers can share more common code.  A couple platform
     drivers are added on top of that and several are added to replace
     older drivers which were doing their own things (older ones are
     scheduled to be removed).

   - Dan finishes the patchset to make libata PM operations
     asynchronous.  Combined with one patch being routed through scsi,
     this should speed resume measurably.

   - Various fixes and cleanups from Bartlomiej and others"
