commit d29f592929489d0a7c414396fae28119f3d280e1 upstream.
(i) pressure is 20-bit unsigned, not signed; the buffer description
is incorrect; for raw reads, this is just cosmetic
(ii) temperature is 12-bit signed, not 16-bit; this affects
readout of temperatures below zero as the sign bit is incorrectly
processed

commit 19bc4981a213d0c5b0e1e8b08815c0b26f01ec54 upstream.
All channels' single measurement are happening on CH 0. So enabling / disabling
the divider once is not enough, because it has impact on all channels.
Set only a flag, then check this on each measurement, and enable / disable the
divider as required.

commit ae339336dc950b9b05e7ccd3565dd3e8781c06d9 upstream.
The current code posts periodic memory pressure status from a dedicated thread.
Under some conditions, especially when we are releasing a lot of memory into
the guest, we may not send timely pressure reports back to the host. Fix this
issue by reporting pressure in all contexts that can be active in this driver.

commit 140cb81ac8c625942a1d695875932c615767a526 upstream.
The current ACM runtime-suspend implementation is broken in several
ways:
Firstly, it buffers only the first write request being made while
suspended -- any further writes are silently dropped.
Secondly, writes being dropped also leak write urbs, which are never
reclaimed (until the device is unbound).
Thirdly, even the single buffered write is not cleared at shutdown
(which may happen before the device is resumed), something which can
lead to another urb leak as well as a PM usage-counter leak.
Fix this by implementing a delayed-write queue using urb anchors and
making sure to discard the queue properly at shutdown.

commit e144ed28bed10684f9aaec6325ed974d53f76110 upstream.
Fix race between write() and resume() due to improper locking that could
lead to writes being reordered.
Resume must be done atomically and susp_count be protected by the
write_lock in order to prevent racing with write(). This could otherwise
lead to writes being reordered if write() grabs the write_lock after
susp_count is decremented, but before the delayed urb is submitted.

Fix race between write() and suspend() which could lead to writes being
dropped (or I/O while suspended) if the device is runtime suspended
while a write request is being processed.
Specifically, suspend() releases the write_lock after determining the
device is idle but before incrementing the susp_count, thus leaving a
window where a concurrent write() can submit an urb.

[ Upstream commit da1de8dfff09d33d4a5345762c21b487028e25f5 ]
Following commit befdf89 "net/mlx4_core: Preserve pci_dev_data after
__mlx4_remove_one()", there are two mlx4 pci callbacks which will
attempt to release the mlx4_priv object -- .shutdown and .remove.
This leads to a use-after-free access to the already freed mlx4_priv
instance and trigger a "Kernel access of bad area" crash when both
.shutdown and .remove are called.
During reboot or kexec, .shutdown is called, with the VFs probed to
the host going through shutdown first and then the PF. Later, the PF
will trigger VFs' .remove since VFs still have driver attached.
Fix that by keeping only one driver entry which releases mlx4_priv.

someone binds the driver to a device manually using

This patch wrap up a helper function __mlx4_remove_one() which does the tear

releasing drvdata.

[ Upstream commit 2853af6a2ea1a8ed09b09dd4fb578e7f435e8d34 ]
When we mirror packets from a vxlan tunnel to other device,
the mirror device should see the same packets (that is, without
outer header). Because vxlan tunnel sets dev->hard_header_len,
tcf_mirred() resets mac header back to outer mac, the mirror device
actually sees packets with outer headers
Vxlan tunnel should set dev->needed_headroom instead of
dev->hard_header_len, like what other ip tunnels do. This fixes
the above problem.

[ Upstream commit daf37b556e437ec1ea1a597dcfeff338068380e1 ]
Fixes:ee45fd92c739
("sfc: Use TX PIO for sufficiently small packets")
The linux net driver uses memcpy_toio() in order to copy into
the PIO buffers.
Even on a 64bit machine this causes 32bit accesses to a write-
combined memory region.
There are hardware limitations that mean that only 64bit
naturally aligned accesses are safe in all cases.
Due to being write-combined memory region two 32bit accesses
may be coalesced to form a 64bit non 64bit aligned access.
Solution was to open-code the memory copy routines using pointers
and to only enable PIO for x86_64 machines.
Not tested on platforms other than x86_64 because this patch
disables the PIO feature on other platforms.
Compile-tested on x86 to ensure that works.
The WARN_ON_ONCE() code in the previous version of this patch
has been moved into the internal sfc debug driver as the
assertion was unnecessary in the upstream kernel code.
This bug fix applies to v3.13 and v3.14 stable branches.

[ Upstream commit 530aa2d0d9d55ab2775d47621ddf4b5b15bc1110 ]
The current behaviour of the sh_eth driver is not to use the RNC bit
for the receive ring. This means that every packet recieved is not only
generating an IRQ but it also stops the receive ring DMA as well until
the driver re-enables it after unloading the packet.
This means that a number of the following errors are generated due to
the receive packet FIFO overflowing due to nowhere to put packets:
net eth0: Receive FIFO Overflow
Since feedback from Yoshihiro Shimoda shows that every supported LSI
for this driver should have the bit enabled it seems the best way is
to remove the RMCR default value from the per-system data and just
write it when initialising the RMCR value. This is discussed in
the message (http://www.spinics.net/lists/netdev/msg284912.html).
I have tested the RMCR_RNC configuration with NFS root filesystem and
the driver has not failed yet. There are further test reports from
Sergei Shtylov and others for both the R8A7790 and R8A7791.
There is also feedback fron Cao Minh Hiep[1] which reports the
same issue in (http://comments.gmane.org/gmane.linux.network/316285)
showing this fixes issues with losing UDP datagrams under iperf.

[ Upstream commit 9d0d68faea6962d62dd501cd6e71ce5cc8ed262b ]
Now it is not possible to set mtu to team device which has a port
enslaved to it. The reason is that when team_change_mtu() calls
dev_set_mtu() for port device, notificator for NETDEV_PRECHANGEMTU
event is called and team_device_event() returns NOTIFY_BAD forbidding
the change. So fix this by returning NOTIFY_DONE here in case team is
changing mtu in team_change_mtu().

Which act the same as the previous calls except they verify that the

within target_put_sess_cmd(), and call se_cmd->se_tfo->release_cmd()
to release the XCOPY's xcopy_pt_cmd memory.

commit 2fe121e1f5aa3bf31b418a9790db6c400e922291 upstream.
The rtc user must wait at least 1 sec between each time/calandar update
(see atmel's datasheet chapter "Updating Time/Calendar").
Use the 1Hz interrupt to update the at91_rtc_upd_rdy flag and wait for
the at91_rtc_wait_upd_rdy event if the rtc is not ready.
This patch fixes a deadlock in an uninterruptible wait when the RTC is
updated more than once every second. AFAICT the bug is here from the
beginning, but I think we should at least backport this fix to 3.10 and
the following longterm and stable releases.

commit b04ada92ffaabb868497a1fce8e4f6bf74e5488f upstream.
We cleared H_RST for H_CSR on spurious interrupt generated when ME_RDY
while cleared and not while ME_RDY is set. The spurious interrupt
is not delivered on all platforms in this case the
driver may fail to initialize.

commit b701c0b1fe819a2083fc6ec5332e0e4492b9516d upstream.
free_msi_irqs() is leaking memory, since list_for_each_entry(entry,
&dev->msi_list, list) {...} is never executed, because dev->msi_list is
made empty by the loop just above this one.
Fix it by relying on zero termination of attribute array like
populate_msi_sysfs() does.

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.
This patch fixes a iser-target specific regression introduced in
v3.15-rc6 with:
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.

Based on commit ea8ea460c9ace60bbb5ac6e5521d637d5c15293d upstream
This missing IOTLB flush was added as a minor, inconsequential bug-fix
in commit ea8ea460c ("iommu/vt-d: Clean up and fix page table clear/free
behaviour") in 3.15. It wasn't originally intended for -stable but a
couple of users have reported issues which turn out to be fixed by
adding the missing flush.

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.
