Highbank supports SGPIO by bit-banging out the SGPIO signals over
three GPIO pins defined in the DTB. Add support for this SGPIO
functionality.

Create a new ata_port_operations function pointer called
transmit_led_message and give it the default value of
ahci_transmit_led_message. This allows AHCI controllers with
non-standard LED interfaces to use the existing em_ interface.

Use the wrapper function for getting the driver data using pci_dev
instead of using dev_get_drvdata() with &pdev->dev, so we can directly
pass a struct pci_dev. This is a purely cosmetic change.

The 'ctl' field of the 'struct ata_taskfile' is not really dual purpose, i.e.
it is not intended for storing the alternate status register (which is mapped
at the same address in the legacy IDE controllers) in the qc_fill_rtf() method.
No other 'libata' driver except 'drivers/scsi/ipr.c' stores the alternate status
register's value in the 'ctl' field of 'qc->result_tf', hence this driver should
not do this as well...

The 'base' field of 'struct sata_rcar_priv' is used very often
throughout the driver, so it seems worth loading it into a local
variable if it's used more than once in a function.
While at it, put some unitialized variables after intialized ones for
aesthetic reasons. :-)

Using ATA_BMDMA_SHT() to intialize 'sata_rcar_sht' was suboptimal as
the R-Car descriptor table transfer counter is 28 bits wide (bit 1 to
bit 28), so that the 'dma_boundary' field of 0xFFFF is just too small,
as well as the 'sg_tablesize' field of 128. Use ATA_BASE_SHT() to
initialize 'sata_rcar_sht' instead and give proper values to the
'dma_boundary' and 'sg_tablesize' fields explicitly.

I've modified sata_rcar_bmdma_fill_sg() to take care of splitting long
scatter/ gather segments due to the descriptor table transfer counter
being only 28 bits wide (bit 1 to bit 28) but that was in vain as even
if 'sata_rcar_sht' specified a correct 'dma_boundary' field, the DMA
and block layers would have split the S/G segments on the necassary
boundaries. Since the driver uses ATA_BMDMA_SHT() to initilaize
'sata_rcar_sht', the boundary is much smaller, only 0xFFFF, so the
code I've added is even more useless, and it's better to just remove
it.

The motivation for this is to allow the driver to be
used with the r8a7790 SoC.
I believe that rather than adding another SoC to the list of allowed SoCs
it is better to simply remove the dependency of the driver on shmobile all
together.

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.
Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

Some device require DMADIR to be enabled, but are not detected as such
by atapi_id_dmadir. One such example is "Asus Serillel 2"
SATA-host-to-PATA-device bridge: the bridge itself requires DMADIR,
even if the bridged device does not.
As atapi_dmadir module parameter can cause problems with some devices
(as per Tejun Heo's memory), enabling it globally may not be possible
depending on the hardware.
This patch adds atapi_dmadir in the form of a "force" horkage value,
allowing global, per-bus and per-device control.

Pull tracing/kprobes update from Steven Rostedt:
"The majority of these changes are from Masami Hiramatsu bringing
kprobes up to par with the latest changes to ftrace (multi buffering
and the new function probes).
He also discovered and fixed some bugs in doing so. When pulling in
his patches, I also found a few minor bugs as well and fixed them.
This also includes a compile fix for some archs that select the ring
buffer but not tracing.
I based this off of the last patch you took from me that fixed the
merge conflict error, as that was the commit that had all the changes
I needed for this set of changes."
