commit db8b10167126d72829653690f57b9c7ca53c4d54 upstream.
Re-initializing the wait object in rdma_init()/rdma_fini() causes a
timing window which can lead to a deadlock during close. Once this
deadlock hits, all RDMA activity over the T4 device will be stuck.
There's no need to re-init the wait object, so remove it.

According to rfc 3530 BADNAME is for strings that represent paths;
BADOWNER is for user/group names that don't map.
And the too-long name should probably be BADOWNER as well; it's

To address this, prevent the NFS direct I/O engine from completing
async iocbs when the forward path returns an error without starting
any I/O.

commit 4514e8997fbefd5befd6176ac9785e287b4daed4 upstream.
When we disable the WM8994 FLL code path sharing means that we end up
writing out a configuration. Currently this is the currently active
input and output frequency (which causes snd_soc_update_bits() to
suppress actual writes both immediately and in the common case where
we reenable the same configuration later) but we allow machine drivers
to pass through a source of zero. Since the register values written
are one less than the source constants this causes corruption of other
bitfields in the register.
Fix this by using the most recently configured FLL source when none is
provided.

If a timer interrupt was delayed too much, hrtimer_forward_now() will
forward the timer expiry more than once. When this happens, the

commit 0ebaa24c6b1f62839bcd12d63fa76e3cf23b9bd0 upstream.
The dynamic PCM restriction based on ELD information may lead to the
problem in some cases, e.g. when the receiver is turned off. Then it
may send a TV HDMI default such as channels = 2. Since it's still
plugged, the driver doesn't know whether it's the right configuration
for future use. Now, when an app opens the device at this moment,
then turn on the receiver, the app still sends channels=2.
The right solution is to implement some kind of notification and
automatic re-open mechanism. But, this is a goal far ahead.
This patch provides a workaround for such a case by providing a new
module option static_hdmi_pcm for snd-hda-codec-hdmi module. When
this is set to true, the driver doesn't change PCM parameters per
ELD information. For users who need the static configuration like
the scenario above, set this to true.
The parameter can be changed dynamically via sysfs, too.

After a module loads you will have loaded the world roaming regulatory
domain or a custom regulatory domain. Further regulatory hints are
welcomed and should be respected unless the regulatory hint is coming
from a country IE as the IEEE spec allows for a country IE to be a subset
of what is allowed by the local regulatory agencies.
So disable all channels that do not fit a regulatory domain sent
from a unless the hint is from a country IE and the country IE had
no information about the band we are currently processing.
This fixes a few regulatory issues, for example for drivers that depend
on CRDA and had no 5 GHz freqencies allowed were not properly disabling
5 GHz at all, furthermore it also allows users to restrict devices
further as was intended.
If you recieve a country IE upon association we will also disable the
channels that are not allowed if the country IE had at least one
channel on the respective band we are procesing.
This was the original intention behind this design but it was
completely overlooked...

There was a configuration page timing out during the initial port
enable at driver load time. The port enable would fail, and this would
result in the driver unloading itself, meanwhile the driver was accessing
freed memory in another context resulting in the panic. The fix is to
prevent access to freed memory once the driver had issued the diag reset
which woke up the sleeping port enable process. The routine
_base_reset_handler was reorganized so the last sleeping process woken up was
the port_enable.

event processing routine due to a race between accessing the scsi command
pointer from broadcast asyn event processing thread and completing
the same scsi command from the interrupt context.
(2) Broadcast asyn event notifcations are not handled due to events
ignored while the broadcast asyn event is activity being processed
from the event process kernel thread.
In addition, changed the ABRT_TASK_SET to ABORT_TASK in the
broadcast async event processing routine. This is less disruptive to other
request that generate Broadcast Asyn Primitives besides target
reset. e.g clear reservations, microcode download,and mode select.

commit efe82a16bc0f9f9e1fc8fa706eb0309fcd57770a upstream.
The "internal device reset complete" event is not supported
for older firmware prior to MPI Rev K We added
a check in the driver so the "internal device reset" event is
ignored for older firmware. When ignored, the tm_busy flag doesn't
get set nor cleared. Without this fix, IO queues would be froozen
indefinetly after the "internal device reset" event, as the "complete" event
never sent to clear the flag.

commit 4dc2757a2e9a9d1f2faee4fc6119276fc0061c16 upstream.
When zoning end devices, the driver is not sending device
removal handshake alogrithm to firmware. This results in controller
firmware not sending sas topology add events the next time the device is
added. The fix is the driver should be doing the device removal handshake
even though the PHYSTATUS_VACANT bit is set in the PhyStatus of the
event data. The current design is avoiding the handshake when the
VACANT bit is set in the phy status.

commit 3a9c913a3e57b170887d39456e04c18f2305ec67 upstream.
Issue:
IR shutdown(sending) and IR shutdown(complete) messages not
listed in /var/log/messages when driver is removed.
The driver needs to issue a MPI2_RAID_ACTION_SYSTEM_SHUTDOWN_INITIATED
request when the driver is unloaded so the IR metadata journal is updated.
If this request is not sent, then the volume would need a "check
consistency" issued on the next bootup if the volume was roamed from one
initiator to another. The current driver supports this feature only when the
system is rebooted, however this also need to be supported if the driver is
unloaded
Fix:
To fix this issue, the driver is going
to need to call the _scsih_ir_shutdown prior to reporting
the volumes missing from the OS, hence the device handles
are still present.

commit 9ee91f7fb550a4c82f82d9818e42493484c754af upstream.
libsas makes use of scsi_schedule_eh() but forgets to clear the
host_eh_scheduled flag in its error handling routine. Because of this,
the error handler thread never gets to sleep; it's constantly awake and
trying to run the error routine leading to console spew and inability to
run anything else (at least on a UP system). The fix is to clear the
flag as we splice the work queue.

commit a8733c7baf457b071528e385a0b7d4aaec79287c upstream.
Our current handling of medium error assumes that data is returned up
to the bad sector. This assumption holds good for all disk devices,
all DIF arrays and most ordinary arrays. However, an LSI array engine
was recently discovered which reports a medium error without returning
any data. This means that when we report good data up to the medium
error, we've reported junk originally in the buffer as good. Worse,
if the read consists of requested data plus a readahead, and the error
occurs in readahead, we'll just strip off the readahead and report
junk up to userspace as good data with no error.
The fix for this is to have the error position computation take into
account the amount of data returned by the driver using the scsi
residual data. Unfortunately, not every driver fills in this data,
but for those who don't, it's set to zero, which means we'll think a
full set of data was transferred and the behaviour will be identical
to the prior behaviour of the code (believe the buffer up to the error
sector). All modern drivers seem to set the residual, so that should
fix up the LSI failure/corruption case.

Fix the check for ap interupts to look for facility bits 2 and 65.
Make sure that we only register interrupts for aps, if the machine
has ap interrupt support.
This patch is relevant only for the 2.6.37 stable series.

If QIOASSIST is enabled for a qdio device the SIGA instruction requires
a modified function code. This function code modifier was missing for
SIGA-R and SIGA-S which can lead to a kernel panic caused by an
