commit d251836508fb26cd1a22b41381739835ee23728d upstream.
This device normally comes with a proprietary driver, using a web GUI
to configure RAID:
http://www.highpoint-tech.com/USA_new/series_rr600-download.htm
But thankfully it also works out of the box with the AHCI driver,
being just a Marvell 88SE9235.
Devices 640L, 644L, 644LS should also be supported but not tested here.

commit e7810c2d2c37fa8e58dda74b00790dab60fe6fba upstream.
This patch allows READ_CAPACITY + SAI_READ_CAPACITY_16 opcode
processing to occur while the associated ALUA group is in Standby
access state.
This is required to avoid host side LUN probe failures during the
initial scan if an ALUA group has already implicitly changed into
Standby access state.
This addresses a bug reported by Chris + Philip using dm-multipath
+ ESX hosts configured with ALUA multipath.

commit 2363d196686e44c0158929e7cf96c8589a24a81b upstream.

commit 14f4b54fe38f3a8f8392a50b951c8aa43b63687a
Author: Sagi Grimberg <sagig@mellanox.com>
Date: Tue Apr 29 13:13:47 2014 +0300
Target/iscsi,iser: Avoid accepting transport connections during stop stage
where the change to set iscsi_np->enabled = false within
iscsit_clear_tpg_np_login_thread() meant that a iscsi_np with
two iscsi_tpg_np exports would have it's parent iscsi_np set
to a disabled state, even if other iscsi_tpg_np exports still
existed.
This patch changes iscsit_clear_tpg_np_login_thread() to only
set iscsi_np->enabled = false when shutdown = true, and also
changes iscsit_del_np() to set iscsi_np->enabled = true when
iscsi_np->np_exports is non zero.

commit 14f4b54fe38f3a8f8392a50b951c8aa43b63687a upstream.
When the target is in stop stage, iSER transport initiates RDMA disconnects.
The iSER initiator may wish to establish a new connection over the
still existing network portal. In this case iSER transport should not
accept and resume new RDMA connections. In order to learn that, iscsi_np
is added with enabled flag so the iSER transport can check when deciding
weather to accept and resume a new connection request.
The iscsi_np is enabled after successful transport setup, and disabled
before iscsi_np login threads are cleaned up.

commit 80f65de3c9b8101c1613fa82df500ba6a099a11c upstream.
Atm we set the parent of the dp i2c device to be the correspondig
connector device. During driver cleanup we first remove the connector
device through intel_modeset_cleanup()->drm_sysfs_connector_remove() and
only after that the i2c device through the encoder's destroy callback.
This order is not supported by the device core and we'll get a warning,
see the below bugzilla ticket. The proper order is to remove first any
child device and only then the parent device.
The first part of the fix changes the i2c device's parent to be the drm
device. Its logical owner is not the connector anyway, but the encoder.
Since the encoder doesn't have a device object, the next best choice is
the drm device. This is the same what we do in the case of the sdvo i2c
device and what the nouveau driver does.
The second part creates a symlink in the connector's sysfs directory
pointing to the i2c device. This is so, that we keep the current ABI,
which also makes sense in case someone wants to look up the i2c device
belonging to a specific connector.

commit 4932e2c3c716067f3580e1a9687bed9d751549e3 upstream.
Since
commit d9255d57147e1dbcebdf6670409c2fa0ac3609e6
Author: Paulo Zanoni <paulo.r.zanoni@intel.com>
Date: Thu Sep 26 20:05:59 2013 -0300
it became clear that we need to separate the unload sequence into two
parts:
1. remove all interfaces through which new operations on some object
(crtc, encoder, connector) can be started and make sure all pending
operations are completed
2. do the actual tear down of the internal representation of the above
objects
The above commit achieved this separation for connectors by splitting
out the sysfs removal part from the connector's destroy callback and
doing this removal before calling drm_mode_config_cleanup() which does
the actual tear-down of all the drm objects.
Since we'll have to customize the interface removal part for different
types of connectors in the upcoming patches, add a new unregister
callback and move the interface removal part to it.
No functional change.

commit f1453773514bb8b0bba0716301e8c8f17f8d39c7 upstream.
This patch fixes a OOPs where an attempt to write to the per-device
alua_access_state configfs attribute at:
/sys/kernel/config/target/core/$HBA/$DEV/alua/$TG_PT_GP/alua_access_state
results in an NULL pointer dereference when the backend device has not
yet been configured.
This patch adds an explicit check for DF_CONFIGURED, and fails with
-ENODEV to avoid this case.

commit 79d59d08082dd0a0a18f8ceb78c99f9f321d72aa upstream.
In non-leading connection login, iscsi_login_non_zero_tsih_s1() calls
iscsi_change_param_value() with the buffer it uses to hold the login
PDU, not a temporary buffer. This leads to the login header getting
corrupted and login failing for non-leading connections in MC/S.
Fix this by adding a wrapper iscsi_change_param_sprintf() that handles
the temporary buffer itself to avoid confusion. Also handle sending a
reject in case of failure in the wrapper, which lets the calling code
get quite a bit smaller and easier to read.
Finally, bump the size of the temporary buffer from 32 to 64 bytes to be
safe, since "MaxRecvDataSegmentLength=" by itself is 25 bytes; with a
trailing NUL, a value >= 1M will lead to a buffer overrun. (This isn't
the default but we don't need to run right at the ragged edge here)

commit 6cc44a6fb46e1ecc1c28125aa8fa34d317aa9ea7 upstream.
This patch addresses a bug where an early exception for SCSI WRITE
with ImmediateData=Yes was missing the target_put_sess_cmd() call
to drop the extra se_cmd->cmd_kref reference obtained during the
normal iscsit_setup_scsi_cmd() codepath execution.
This bug was manifesting itself during session shutdown within
isert_cq_rx_comp_err() where target_wait_for_sess_cmds() would
end up waiting indefinately for the last se_cmd->cmd_kref put to
occur for the failed SCSI WRITE + ImmediateData descriptors.
This fix follows what traditional iscsi-target code already does
for the same failure case within iscsit_get_immediate_data().

commit c4ee841f602e5eef8eab673295c49c5b49d7732b upstream.
The PID assumes that samples are of equal time, which for a deferable
timers this is not true when the system goes idle. This causes the
PID to take a long time to converge to the min P state and depending
on the pattern of the idle load can make the P state appear stuck.
The hold-off value of three sample times before using the scaling is
to give a grace period for applications that have high performance
requirements and spend a lot of time idle, The poster child for this
behavior is the ffmpeg benchmark in the Phoronix test suite.

commit 8ef42ddd9a53b73e6fc3934278710c27f80f324f upstream.
Not all host controller drivers have bus-suspend and bus-resume
methods. When one doesn't, it will cause problems if runtime PM is
enabled in the kernel. The PM core will attempt to suspend the
controller's root hub, the suspend will fail because there is no
bus-suspend routine, and a -EBUSY error code will be returned to the
PM core. This will cause the suspend attempt to be repeated shortly
thereafter, in a never-ending loop.
Part of the problem is that the original error code -ENOENT gets
changed to -EBUSY in usb_runtime_suspend(), on the grounds that the PM
core will interpret -ENOENT as meaning that the root hub has gotten
into a runtime-PM error state. While this change is appropriate for
real USB devices, it's not such a good idea for a root hub. In fact,
considering the root hub to be in a runtime-PM error state would not
be far from the truth. Therefore this patch updates
usb_runtime_suspend() so that it adjusts error codes only for
non-root-hub devices.
Furthermore, the patch attempts to prevent the problem from occurring
in the first place by not enabling runtime PM by default for root hubs
whose host controller driver doesn't have bus_suspend and bus_resume
methods.

commit c03890ff5e24a4bf59059f2d179f427559b7330a upstream.
A recent patch that purported to fix firmware download on big-endian
machines failed to add the corresponding sparse annotation to the
i2c-header. This was reported by the kbuild test robot.
Adding the appropriate annotation revealed another endianess bug related
to the i2c-header Size-field in a code path that is exercised when the
firmware is actually being downloaded (and not just verified and left
untouched unless older than the firmware at hand).
This patch adds the required sparse annotation to the i2c-header and
makes sure that the Size-field is sent in little-endian byte order
during firmware download also on big-endian machines.
Note that this patch is only compile-tested, but that there is no
functional change for little-endian systems.

commit 9326c5ca0982f548cc08c0cffb14dcbd020f3d43 upstream.
A sparse error fixup removed a htons() which is required for the driver
to function. This patch puts the htons() back and fixes the sparse
warning correctly by changing the left side cast.

commit 28a821c306889b9f2c3fff49abedc9b2c743eb73 upstream.
This function is largely a duplicate of paste_selection() in
drivers/tty/vt/selection.c, but with its own selection state. The
speakup selection mechanism should really be merged with vt.
For now, apply the changes from 'TTY: vt, fix paste_selection ldisc
handling', 'tty: Make ldisc input flow control concurrency-friendly',
and 'tty: Fix unsafe vt paste_selection()'.

commit d7500135802ca55b3f4e01a16544e8b34082f8c3 upstream.
Input is handled in softirq context, but when pasting we may
need to sleep. speakup_paste_selection() currently tries to
bodge this by busy-waiting if in_atomic(), but that doesn't
help because the ldisc may also sleep.
For bonus breakage, speakup_paste_selection() changes the
state of current, even though it's not running in process
context.
Move it into a work item and make sure to cancel it on exit.

commit 5dc2808c4729bf080487e61b80ee04e0fdb12a37 upstream.
Lists of endpoints are stored for bandwidth calculation for roothub ports.
Make sure we remove all endpoints from the list before the whole device,
containing its endpoints list_head stuctures, is freed.
This used to be done in the wrong order in xhci_mem_cleanup(),
and triggered an oops in resume from S4 (hibernate).

commit 2ac295a544dcae9299cba13ce250419117ae7fd1 upstream.
Commit 8313b8e57f55b15e5b7f7fc5d1630bbf686a9a97
md: fix problem when adding device to read-only array with bitmap.
added a called to md_reap_sync_thread() which cause a reshape thread
to be interrupted (in particular, it could cause md_thread() to never even
call md_do_sync()).
However it didn't set MD_RECOVERY_INTR so ->finish_reshape() would not
know that the reshape didn't complete.
This only happens when mddev->ro is set and normally reshape threads
don't run in that situation. But raid5 and raid10 can start a reshape
thread during "run" is the array is in the middle of a reshape.
They do this even if ->ro is set.
So it is best to set MD_RECOVERY_INTR before abortingg the
sync thread, just in case.
Though it rare for this to trigger a problem it can cause data corruption
because the reshape isn't finished properly.
So it is suitable for any stable which the offending commit was applied to.
(3.2 or later)

commit 3991b31ea072b070081ca3bfa860a077eda67de5 upstream.
If mddev->ro is set, md_to_sync will (correctly) abort.
However in that case MD_RECOVERY_INTR isn't set.
If a RESHAPE had been requested, then ->finish_reshape() will be
called and it will think the reshape was successful even though
nothing happened.
Normally a resync will not be requested if ->ro is set, but if an
array is stopped while a reshape is on-going, then when the array is
started, the reshape will be restarted. If the array is also set
read-only at this point, the reshape will instantly appear to success,
resulting in data corruption.
Consequently, this patch is suitable for any -stable kernel.

Queued trim only works for some users with MU05 firmware. Revert to

Introduced by commit d121f7d0cbb8 ("libata: Update queued trim blacklist
for M5x0 drives") which this effectively reverts, while retaining the
blacklisting of M550.

the power state set from dpm resume. The power state
will get set as part of the mode set sequence. Also
add an explicit power state set after mode set resume

commit 9aab8bff7aa3bee567213ad3c1fdfb217bb980a2 upstream.
We only want to modifiy a single field in the userspace view of the
execbuffer command buffer, so explicitly change that rather than copy
everything back again.
This serves two purposes:
1. The single fields are much cheaper to copy (constant size so the
copy uses special case code) and much smaller than the whole array.
2. We modify the array for internal use that need to be masked from
the user.
Note: We need this backported since without it the next bugfix will
blow up when userspace recycles batchbuffers and relocations.

commit aa0818c6ee8d8e4772725a43550823347bc1ad30 upstream.
When there isn't enough vring descriptor for adding to vq,
blk-mq will be put as stopped state until some of pending
descriptors are completed & freed.
Unfortunately, the vq's interrupt may come just before
blk-mq's BLK_MQ_S_STOPPED flag is set, so the blk-mq will
still be kept as stopped even though lots of descriptors
are completed and freed in the interrupt handler. The worst
case is that all pending descriptors are freed in the
interrupt handler, and the queue is kept as stopped forever.
This patch fixes the problem by starting/stopping blk-mq
with holding vq_lock.

commit 80c578930ce77ba8bcfb226a184b482020bdda7b upstream.
Commit 85ad643b ("dm thin: add timeout to stop out-of-data-space mode
holding IO forever") introduced a fixed 60 second timeout. Users may
want to either disable or modify this timeout.
Allow the out-of-data-space timeout to be configured using the
'no_space_timeout' dm-thin-pool module param. Setting it to 0 will
disable the timeout, resulting in IO being queued until more data space
is added to the thin-pool.

commit 2fe2023adf695d08af5b598b2be3b288a95d563c upstream.
Undo a feature introduced in v3.14 by commit fcd46b34425d
"firewire: Enable remote DMA above 4 GB". That change raised the
minimum address at which protocol drivers and user programs can register
for request reception from 0x0001'0000'0000 to 0x8000'0000'0000.
It turned out that at least one vendor-specific protocol exists which
uses lower addresses: https://bugzilla.kernel.org/show_bug.cgi?id=76921
For the time being, revert most of commit fcd46b34425d so that affected
protocols work like with kernel v3.13 and before. Just keep the valid
documentation parts from the regressing commit, and the ability to
identify controllers which could be programmed to accept >32 bit
physical DMA addresses. The rest of fcd46b34425d should probably be
brought back as an optional instead of default feature.

commit e3beb0ac521d50d158a9d253373eae8421ac3998 upstream.
This driver is using devres managed calls incorrectly, giving the cpu0
device as first parameter instead of the cpufreq platform device.
This results in resources not being freed if the cpufreq platform device
is unbound, for example if probing has to be deferred for a missing
regulator.
