The sata_mv driver supports the SATA IP found in several Marvell SoCs.
As some new SATA registers have been introduced with the Armada 370/XP
SoCs, a way to identify them is needed.

This patch introduces a new compatible string for the SATA IP found in
Armada 370/XP SoCs.

Add minor adjustments to support i.MX53 SATA port as well as i.MX6Q one.
The difference here is mostly the clock which need to be enabled and also
the lack of need of programming IOMUXC registers on i.MX53. All of which
is well handles in the clock enable/disable functions. Note that this patch
also cleans up the names of the common functions, so they don't read imx6q_*
but imx_* instead.

R-Car Gen2 SoCs have a different PHY which is not compatible
with the older R-Car H1 (R8A7779) version.
This adds OF/platform device id tables and PHY initialization
callbacks for the following Gen2 SoCs:
  * R-Car H2: R8A7790;
  * R-Car M2: R8A7791.

PHY initialization method is chosen based on the device id.
Default PHY settings are applied for Gen2 SoCs, which should
suit the Gen2 boards available.

While at it, this also adds "sata-r8a7779" compatibility string
for R8A7779 SATA, while keeping the old one for compatibility.

The source of this problem is that SCSI hosts are removed from
ATA ports after calling ata_tport_delete() which removes the
port's sysfs directory, among other things.  Now, after commit
bcdde7e2, the sysfs directory is removed along with all of
its subdirectories that include the SCSI host's sysfs directory
and its subdirectories at this point.  Consequently, when
device_del() is finally called for any child device of the SCSI
host and tries to remove its "power" group (which is already
gone then), it triggers the above warning.

To make the warnings go away, change the removal ordering in
ata_port_detach() so that the SCSI host is removed from the
port before ata_tport_delete() is called.

  Here we have a performance fix for inode iversion, increased inode
  cluster size for v5 superblock filesystems, a fix for error handling
  in xfs_bmap_add_attrfork, and a MAINTAINERS update to add Dave"

 "The patches from Joonsoo Kim switch mm/slab.c to use 'struct page' for
  slab internals similar to mm/slub.c.  This reduces memory usage and
  improves performance:

Pull third set of powerpc updates from Benjamin Herrenschmidt:
 "This is a small collection of random bug fixes and a few improvements
  of Oops output which I deemed valuable enough to include as well.

  The fixes are essentially recent build breakage and regressions, and a
  couple of older bugs such as the DTL log duplication, the EEH issue
  with PCI_COMMAND_MASTER and the problem with small contexts passed to
  get/set_context with VSX enabled"
