Fixed trivial conflict in include/linux/memory.h due to semaphore header
file change (made irrelevant by the change to mutex).
None of these files use any of the functionality promised by
asm/semaphore.h. It's possible that they rely on it dragging in some
unrelated header file, but I can't build all these files, so we'll have
fix any build failures as they come up.

The kernel now panics reliably on boot if you have a SATAPI device
connected.
The problem was introduced by the libata merge trying to pull out all
the SFF code into a separate module. Unfortunately, if you're a satapi
device you usually need to call atapi_request_sense, which has a bare
invocation of a SFF callback which is NULL on non-SFF HBAs. Fix this by
making the call conditional.

sata_mv does not yet fully support hotplug (coming soon, though).
This means that the driver may not find a Silicon Image port-multiplier
when first loaded, because those devices take in exceess of 3 seconds
to sync up the SATA PHY (most devices do this in mere microseconds).
So, as a short-term interim measure, here we insert a 3-second pause
on initial driver load, once per controller board (not once per port!),
to allow the Silicon Image port-multipliers to be detected later.
This will be removed again (soon!) once hotplug is fully implemented/working.

Add basic port-multiplier support to sata_mv.
This works in Command-based-switching mode for Gen-II chipsets,
and in FIS-based-switching mode for Gen-IIe chipsets.
Error handling remains at the primary port level for now
(works okay, but not great). This will get fixed in a subsequent
patch series for IRQ/EH handling fixes. There are also some
known NCQ/PMP errata to be dealt with in the near future,
once we have this basic PMP support in place.

The System-On-Chip (SOC) core supports all of the same
features as the other recent Marvell chips,
including NCQ and IRQ coalescing.
Fix the chip_soc flags to enable these capabilities
(note that the driver currently does nothing special
for IRQ coalescing, though).

Rework and simplify sata_mv's hardreset code to take advantage of
libata improvements since it was first coded.
Also, get rid of the now unnecessary prereset, postreset, and phy_reset
functions.
This patch also paves the way for subsequent pmp support patches,
which will follow once this one passes muster.

When no reset method is available, libata currently oopses. Although
the condition can't happen unless there's a bug in a low level driver,
oopsing isn't the best way to report the error condition. Complain,
dump stack and fail reset instead.

We have a certain number of 'ATA' emulations often on CF or other flash
devices that are at best "loosely based" on the CF 1.1 standard. These
devices report themselves as disk but don't support the ATA minimal
command set only the CF 1.1 set.
Relax the PIO checking for devices reporting ATA rev 0, or no iordy
support, or CFA. Rework the code a bit as it was already messy and this
made it quite ugly.

Currently, SATA softresets should do link onlineness check before
actually performing SRST protocol but it doesn't really belong to
softreset.
This patch moves onlineness check in softreset to ata_eh_reset() and
ata_eh_followup_srst_needed() to clean up code and help future sata_mv
changes which need clear separation between SCR and TF accesses.
sata_fsl is peculiar in that its softreset really isn't softreset but
combination of hardreset and softreset. This patch adds dummy private
->prereset to keep the current behavior but the driver really should
implement separate hard and soft resets and return -EAGAIN from
hardreset if it should be follwed by softreset.

Some code paths which had been made obsolete by recent reset
simplification were still around. Kill them.
* ata_eh_reset() checked for ATA_DEV_UNKNOWN to determine
classification failure. This is no longer applicable.
* ata_do_reset() should convert ATA_DEV_UNKNOWN to ATA_DEV_NONE
regardless of reset result (e.g. -EAGAIN).
* LLDs don't need to convert ATA_DEV_UNKNOWN to ATA_DEV_NONE.

Make PMP support optional by adding CONFIG_SATA_PMP and leaving out
libata-pmp.c if it isn't set. PMP helpers return constant values if
PMP support is not enabled and PMP declarations alias non-PMP
counterparts. This makes the compiler to leave out PMP related part
out and LLDs to use non-PMP counterparts automatically.

Implement helpers to test whether PMP is supported, attached and
determine pmp number to use when issuing SRST to a link. While at it,
move ata_is_host_link() so that it's together with the two new PMP
helpers.
This change simplifies LLDs and helps making PMP support optional.
