Every attempt to issue a read log page command lockup the controller.
The command is currently sent if the sata device includes the devlsp feature
to read out the timing data.
This attempt to read the data, locks up the controller and the device
is not recognzied correctly (failed to set xfermode) and cannot be accessed.
This was found on Freescale P1013/P1022 and T4240 CPUs
using a ATP IG mSATA 4GB with the devslp feature.

Some controller lockup on a ata_read_log_page.
Add new ata port flag ATA_FLAG_NO_LOG_PAGE which can used
to blacklist a controller.
If this flag is set, any attempt to read a log page returns an error
without actually issuing the command.

When I connect an Intel SSD to SATA SIL controller (PCI ID 1095:3114), any
TRIM command results in I/O errors being reported in the log. There is
other similar error reported with TRIM and the SIL controller:
https://bugs.centos.org/view.php?id=5880
Apparently the controller doesn't support TRIM commands. This patch
disables TRIM support on the SATA SIL controller.

Current code doesn't update port value of Port Multiplier(PM) when
sending FIS of softreset to device, command will fail if FBS is
enabled.
There are two ways to fix the issue: the first is to disable FBS
before sending softreset command to PM device and the second is
to update port value of PM when sending command.
For the first way, i can't find any related rule in AHCI Spec. The
second way can avoid disabling FBS and has better performance.

Pull final round of SCSI updates from James Bottomley:
"Sorry for the delay in this patch which was mostly caused by getting
the merger of the mpt2/mpt3sas driver, which was seen as an essential
item of maintenance work to do before the drivers diverge too much.
Unfortunately, this caused a compile failure (detected by linux-next),
which then had to be fixed up and incubated.
In addition to the mpt2/3sas rework, there are updates from pm80xx,
lpfc, bnx2fc, hpsa, ipr, aacraid, megaraid_sas, storvsc and ufs plus
an assortment of changes including some year 2038 issues, a fix for a
remove before detach issue in some drivers and a couple of other minor
issues"

This patch changes the !blk-mq path to the same defaults as the blk-mq
I/O path by always enabling block tagging, and always using host wide
tags. We've had blk-mq available for a few releases so bugs with
this mode should have been ironed out, and this ensures we get better
coverage of over tagging setup over different configs.

When calling ->done before releasing resources we could run into a
race where the SCSI midlayer sends another command and races with
the resources beeing manipulated. For libata this can't currently
happen as synchronization happens at a higher level, but I'd still
like to fix it to future proof libata and to avoid copy & paste
into SCSI drivers where this pattern has led to reproducible crashes.

If the AHCI ports' HPCP or ESP bits are set, the port
should be considered external (e.g. eSATA) and is marked
as removable. Userspace tools like udisks then treat it
like an usb drive.
With this patch applied, when I plug a drive into the esata port,
KDE pops up a window asking what to do with the drives(s), just
like it does for any random USB stick.
Removability is indicated to the upper layers by way of the
SCSI RMB bit, as I haven't found another way to signal
userspace to treat a sata disk like any usb stick.

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.
This patch adds the missing MODULE_DEVICE_TABLE() for OF to export
that information so modules have the correct aliases built-in and
autoloading works correctly.
