[GIT PULL] libata changes for 4.1-rc1

[Tejun Heo]

Hello, Linus.

* Hannes's patchset implements support for better error reporting
  introduced by the new ATA command spec.

* The deperecated pci_ dma API usages have been replaced by dma_ ones.

* A bunch of hardware specific updates and some cleanups.

This pull request causes the following conflict in
include/linux/libata.h.

	  ATA_FLAG_NO_DIPM	= (1 << 23), /* host not happy with DIPM */
  <<<<<<< HEAD
	  ATA_FLAG_LOWTAG		= (1 << 24), /* host wants lowest available tag */
	  ATA_FLAG_SAS_HOST	= (1 << 25), /* SAS host */
  =======
  >>>>>>> c54c719b558e0eb3ba60b1390aeb47ed25ff4352

This is a simple context conflict between the following two commits.

  3a02824396c1 ("libata: remove ATA_FLAG_LOWTAG")
  5067c0469c64 ("ata: Add a new flag to destinguish sas controller")

The former removes a flag and the latter adds one.  It can be resolved
as follows.

	  ATA_FLAG_NO_DIPM	= (1 << 23), /* host not happy with DIPM */
	  ATA_FLAG_SAS_HOST	= (1 << 25), /* SAS host */

Thanks.
