commit 09c5b4803a upstream.
When the LPM policy is set to ATA_LPM_MAX_POWER, the device might
generate a spurious PHY event that cuases errors on the link.
Ignore this event if it occured within 10s after the policy change.
The timeout was chosen observing that on a Dell XPS13 9333 these
spurious events can occur up to roughly 6s after the policy change.

commit ce75145267 upstream.
It is possible for ata_sff_flush_pio_task() to set ap->hsm_task_state to
HSM_ST_IDLE in between the time __ata_sff_port_intr() checks for HSM_ST_IDLE
and before it calls ata_sff_hsm_move() causing ata_sff_hsm_move() to BUG().
This problem is hard to reproduce making this patch hard to verify, but this
fix will prevent the race.
I have not been able to reproduce the problem, but here is a crash dump from
a 2.6.32 kernel.
On examining the ata port's state, its hsm_task_state field has a value of HSM_ST_IDLE:
crash> struct ata_port.hsm_task_state ffff881c1121c000
hsm_task_state = 0
Normally, this should not be possible as ata_sff_hsm_move() was called from ata_sff_host_intr(),
which checks hsm_task_state and won't call ata_sff_hsm_move() if it has a HSM_ST_IDLE value.

lspci shows that the driver used for the Broadcom OSB4 IDE Controller is

Kernel driver in use: pata_serverworks
The pata_serverworks driver supports five distinct device IDs,
one being the OSB4 and the other four belonging to the CSB series.
The CSB series appears to support 64-KB DMA transfers,
as tests on a machine with an SAI2 motherboard
containing a Broadcom CSB5 IDE Controller (vendor and device IDs: 1166:0212)
showed no problems with 64-KB DMA transfers.
This problem was first discovered when attempting to install openSUSE
from a DVD on a machine with an STL2 motherboard.
Using the pata_serverworks module,
older releases of openSUSE will not install at all due to the timeouts.
Releases of openSUSE prior to 11.3 can be installed by disabling
the pata_serverworks module using the brokenmodules boot parameter,
which causes the serverworks module to be used instead.
Recent releases of openSUSE (12.2 and later) include better error recovery and
will install, though very slowly.
On all openSUSE releases, the problem can be recreated
on a machine containing a Broadcom OSB4 IDE Controller
by mounting an install DVD and running a command similar to the following:
find /mnt -type f -print | xargs cat > /dev/null
The patch below corrects the problem.
Similar to the other ATA drivers that do not support 64-KB DMA transfers,
the patch changes the ata_port_operations qc_prep vector to point to a routine
that breaks any 64-KB segment into two 32-KB segments and
changes the scsi_host_template sg_tablesize element to reduce by half
the number of scatter/gather elements allowed.
These two changes affect only the OSB4.

The sata on fsl mpc8315e is broken after the commit 8a4aeec8d2
("libata/ahci: accommodate tag ordered controllers"). The reason is
that the ata controller on this SoC only implement a queue depth of
16. When issuing the commands in tag order, all the commands in tag
16 ~ 31 are mapped to tag 0 unconditionally and then causes the sata
malfunction. It makes no senses to use a 32 queue in software while
the hardware has less queue depth. So consider the queue depth
implemented by the hardware when requesting a command tag.

commit 2cf532f5e6 upstream.
In multiple MSI mode all AHCI ports (including dummy) get assigned
separate MSI vectors and (as result of execution
pci_enable_msi_exact() function) separate IRQ numbers, (mapped to the
MSI vectors).
Therefore, although interrupts from dummy ports are not desired they
are still enabled. We do not request IRQs for dummy ports, but that
only means we do not assign AHCI-specific ISRs to corresponding IRQ
numbers.
As result, dummy port interrupts still could come and traverse all the
way from the PCI device to the kernel, causing unnecessary overhead.
This update disables IRQs for dummy ports and prevents the described
issue.

Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
commit ab0f9e78b9 upstream.
The AHCI specification allows hardware to choose to revert to
single MSI mode when fewer messages are allocated than requested.
Yet, at least ICH10 chipset reverts to single MSI mode even when
enough messages are allocated in some cases (see below).
This update forces the driver to not rely on initialization of
multiple MSIs mode alone and always check if "MSI Revert to
Single Message" (MRSM) mode was enforced by the controller and
fallback to the single MSI mode in case it did.
That prevents a situation when the driver configured multiple
per-port IRQ handlers, but the controller sends all port's
interrupts to a single IRQ, which could easily screw up the
interrupt handling and lead to delays and possibly crashes.
The fix was tested on a 6-port controller that successfully
reverted to the single MSI mode:

With 6 ports just 8 MSI vectors should be enough, but the adapter

commit 8a4aeec8d2 upstream.
The AHCI spec allows implementations to issue commands in tag order
rather than FIFO order:
5.3.2.12 P:SelectCmd
HBA sets pSlotLoc = (pSlotLoc + 1) mod (CAP.NCS + 1)
or HBA selects the command to issue that has had the
PxCI bit set to '1' longer than any other command
pending to be issued.
The result is that commands posted sequentially (time-wise) may play out
of sequence when issued by hardware.
This behavior has likely been hidden by drives that arrange for commands
to complete in issue order. However, it appears recent drives (two from
different vendors that we have found so far) inflict out-of-order
completions as a matter of course. So, we need to take care to maintain
ordered submission, otherwise we risk triggering a drive to fall out of
sequential-io automation and back to random-io processing, which incurs
large latency and degrades throughput.
This issue was found in simple benchmarks where QD=2 seq-write
performance was 30-50% *greater* than QD=32 seq-write performance.
Tagging for -stable and making the change globally since it has a low
risk-to-reward ratio. Also, word is that recent versions of an unnamed
OS also does it this way now. So, drives in the field are already
experienced with this tag ordering scheme.

Pull PCI updates from Bjorn Helgaas:
"The most interesting thing here is the change to enable INTx (by
clearing PCI_COMMAND_INTX_DISABLE) if the BIOS left INTx disabled.
Apparently the Baytrail BIOS does this, which means EHCI doesn't work.
Also, fix an AHCI MSI regression and other issues with the recent MSI
changes. This also adds pci_enable_msi_exact() and
pci_enable_msix_exact(), which aren't regression fixes, but will keep
us from touching drivers twice (once to stop using the deprecated
pci_enable_msi(), etc., and again to use the *_exact() variants).
There's also a minor MVEBU fix.

When an error occurs in the port initialization loop, currently the
driver tries to cleanup all the ports. This results in a NULL pointer
dereference if the ports were only partially initialized.
Fix this by updating only the number of initialized ports (either
with failure or successfully), before jumping to the error path
and looping over that number in the cleanup loop.

It's a bit odd to see a newer device showing mod15write; however, the
reported behavior is highly consistent and other factors which could
contribute seem to have been verified well enough. Also, both
sata_sil itself and the drive are fairly outdated at this point making
the risk of this change fairly low. It is possible, probably likely,
that other drive models in the same family have the same problem;
however, for now, let's just add the specific model which was tested.

Pull ACPI and power management updates from Rafael Wysocki:
"As far as the number of commits goes, the top spot belongs to ACPI
this time with cpufreq in the second position and a handful of PM
core, PNP and cpuidle updates. They are fixes and cleanups mostly, as
usual, with a couple of new features in the mix.
The most visible change is probably that we will create struct
acpi_device objects (visible in sysfs) for all devices represented in
the ACPI tables regardless of their status and there will be a new
sysfs attribute under those objects allowing user space to check that
status via _STA.
Consequently, ACPI device eject or generally hot-removal will not
delete those objects, unless the table containing the corresponding
namespace nodes is unloaded, which is extremely rare. Also ACPI
container hotplug will be handled quite a bit differently and cpufreq
will support CPU boost ("turbo") generically and not only in the
acpi-cpufreq driver.
Specifics:
- ACPI core changes to make it create a struct acpi_device object for
every device represented in the ACPI tables during all namespace
scans regardless of the current status of that device. In
accordance with this, ACPI hotplug operations will not delete those
objects, unless the underlying ACPI tables go away.
- On top of the above, new sysfs attribute for ACPI device objects
allowing user space to check device status by triggering the
execution of _STA for its ACPI object. From Srinivas Pandruvada.
