commit b55f84e2d527182e7c611d466cd0bb6ddce201de upstream.
There is a quirk patch 5e5a4f5d5a08c9c504fe956391ac3dae2c66556d
"ata_piix: make DVD Drive recognisable on systems with Intel Sandybridge
chipsets(v2)" fixing the 4 ports IDE controller 32bit PIO mode.
We've hit a problem with DVD not recognized on Haswell Desktop platform which
includes Lynx Point 2-port SATA controller.
This quirk patch disables 32bit PIO on this controller in IDE mode.
v2: Change spelling error in statememnt pointed by Sergei Shtylyov.
v3: Change comment statememnt and spliting line over 80 characters pointed by
Libor Pechacek and also rebase the patch against 3.8-rc7 kernel.

commit a32450e127fc6e5ca6d958ceb3cfea4d30a00846 upstream.
The Slimtype DVD A DS8A8SH drive locks up when max sector is smaller than
65535, and the blow backtrace is observed on locking up:

commit d9904344fc4052fbe7e4dc137eba0dcdadf326bd upstream.
An earlier commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c ("ata_piix:
defer disks to the Hyper-V drivers by default") broke MS Virtual PC
guests. Hyper-V guests and Virtual PC guests have nearly identical DMI
info. As a result the driver does currently ignore the emulated hardware
in Virtual PC guests and defers the handling to hv_blkvsc. Since Virtual
PC does not offer paravirtualized drivers no disks will be found in the
guest.
One difference in the DMI info is the product version. This patch adds a
match for MS Virtual PC 2007 and "unignores" the emulated hardware.
This was reported for openSuSE 12.1 in bugzilla:
https://bugzilla.novell.com/show_bug.cgi?id=737532

commit 5416912af75de9cba5d1c75b99a7888b0bbbd2fb upstream.
ata_device->dma_mode's initial value is zero, which is not a valid dma
mode, but ata_dma_enabled will return true for this value. This patch
sets dma_mode to 0xff in reset function, so that ata_dma_enabled will
not return true for this case, or it will cause problem for pata_acpi.

commit 3100d49d3cd236443faae9d81137c81b22d36003 upstream.
sata_promise's pdc_hard_reset_port() needs to serialize because it
flips a port-specific bit in controller register that's shared by
all ports. The code takes the ata host lock for this, but that's
broken because an interrupt may arrive on our irq during the hard
reset sequence, and that too will take the ata host lock. With
lockdep enabled a big nasty warning is seen.
Fixed by adding private state to the ata host structure, containing
a second lock used only for serializing the hard reset sequences.
This eliminated the lockdep warnings both on my test rig and on
the original reporter's machine.

commit c531077f40abc9f2129c4c83a30b3f8d6ce1c0e7 upstream.
When using my Seagate FreeAgent GoFlex eSATAp external disk enclosure,
interface errors are always seen until 1.5Gbps is negotiated [1]. This
occurs using any disk in the enclosure, and when the disk is connected
directly with a generic passive eSATAp cable, we see stable 3Gbps
operation as expected.
Blacklist 3Gbps mode to avoid dataloss and the ~30s delay bus reset
and renegotiation incurs.

commit cd006086fa5d91414d8ff9ff2b78fbb593878e3c upstream.
When we are hosted on a Microsoft Hyper-V hypervisor the guest disks
are exposed both via the Hyper-V paravirtualised drivers and via an
emulated SATA disk drive. In this case we want to use the paravirtualised
drivers if we can as they are much more efficient. Note that the Hyper-V
paravirtualised drivers only expose the virtual hard disk devices, the
CDROM/DVD devices must still be enumerated.
Mark the host controller ATA_HOST_IGNORE_ATA to prevent enumeration of
disk devices.

Pull libata fixes from Jeff Garzik:
1) Fix regression that could cause a misdiagnosis, which in turn could
lead to an erroneous 3.0 Gbps -> 1.5 downshift, particularly when hotplug
and suspend/resume is involved.
2) Fix a regression that led to ata%d controller ids being numbered one
larger than in <= 3.4-rc3 (oh, the horror!). Controller ids should now be
as expected.
3) add some DT, PCI id's

The change of numbering comes from commit 85d6725b7c0d7e3f ("libata:
make ata_print_id atomic") that changed lines like
ap->print_id = ata_print_id++;
to
ap->print_id = atomic_inc_return(&ata_print_id);
As the latter behaves like ++ata_print_id, we must initialize
it to zero to start the numbering from one.

Commit d902747("[libata] Add ATA transport class") introduced
ATA_EFLAG_OLD_ER to mark entries in the error ring as cleared.
But ata_count_probe_trials_cb() didn't check this flag and it still
counts the old error history. So wrong probe trials count is returned
and it causes problem, for example, SATA link speed is slowed down from
3.0Gbps to 1.5Gbps.
Fix it by checking ATA_EFLAG_OLD_ER in ata_count_probe_trials_cb().

This changes the ordering of initialization and probing events from:

2/ allocate ata_port and schedule port probe in DISCE_PROBE
...to:
1/ allocate ata_port in PORTE_BYTES_DMAED, DISCE_REVALIDATE_DOMAIN
2/ allocate rphy in PORTE_BYTES_DMAED, DISCE_REVALIDATE_DOMAIN
3/ schedule port probe in DISCE_PROBE
This ordering prevents PHYE_SIGNAL_LOSS_EVENTS from sneaking in to
destrory ata devices before they have been fully initialized:

Pull libata updates from Jeff Garzik:
1) AHCI regression fix. A recent "make driver conform to spec" change
broke on deployed hardware. Make new behavior optional, rather than
default, turning it on only for specific embedded platforms that
need this.
Everybody else runs in the famous "non conformant but working" mode.
2) pata_cmd64x, pata_legacy cleanups
3) new Intel SATA PCI IDs
4) misc minor vendor feature additions

Start using faster version of the bmdma_stop() method for the PCI0646U and newer
chips that have the duplicate interrupt status bits in the I/O mapped MRDMODE
register. Use the old, slow bmdma_stop() method on the older chips, taking into
account that the interrupt bits are not coupled to DMA and that's enough to read
the register to clear the interrupt (on the older chips). Determine what method
to use at the driver load time.
Fix kernel-doc of the bmdma_stop() methods, while at it.

This patch makes a number of changes with respect to the error-handling
code:
* Remove cleanup calls for the devm functions in both the error handling
code and the remove function. This cleanup is done automatically.
* The previous change simplifies the cleanup code at the end of the
function such that there is nothing to do on the failure of the call to
devm_ioremap. So it is changed to just return directly.
* There is no need for the ifs in the cleanup code at the end of the
function, because in each case the cleanup needed is statically
known. Drop the ifs, add new err labels, and drop the initializations of
the tested variables to NULL.
* Change the call to request_irq to a call to devm_request_irq, so that it
is cleaned up on exit.
* Cause the return value of devm_request_irq to go into the returned
variable rv rather than the unused variable ret. Drop ret.

The following commit was intended to fix problems with specific AHCI
controller(s) that would become bricks if the AHCI specification was not
followed strictly (that is, if ahci_start_engine() was called while the
controller was in the wrong state):
commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7
ahci: start engine only during soft/hard resets
However, some devices currently have issues with that fix, so we must
implement a flag that delays the ahci_start_engine() call only for specific
controllers.
This commit simply introduces the flag, without enabling it in any driver.
Note that even when AHCI_HFLAG_DELAY_ENGINE is not enabled, this patch does
not constitue a full revert to commit 7faa33da; there is still a change in
behavior to the ahci_port_suspend() failure path.

libsas ata error handling is already async but this does not help the
scan case. Move initial link recovery out from under host->scan_mutex,
and delay synchronization with eh until after all port probe/recovery
work has been queued.
Device ordering is maintained with scan order by still calling
sas_rphy_add() in order of domain discovery.
Since we now scan the domain list when invoking libata-eh we need to be
careful to check for fully initialized ata ports.

Link resets leave ata affiliations intact, so arrange for libsas to make
an effort to avoid dropping the device due to a slow-to-recover link.
Towards this end carry out reset in the host workqueue so that it can
check for ata devices and kick the reset request to libata. Hard
resets, in contrast, bypass libata since they are meant for associating
an ata device with another initiator in the domain (tears down
affiliations).
Need to add a new transport_sas_phy_reset() since the current
sas_phy_reset() is a utility function to libsas lldds. They are not
prepared for it to loop back into eh.
