+Subject: ARM: dts: omap4-droid4: Fix spi configuration and increase rate
+
+From: Tony Lindgren <tony@atomide.com>
+
+[ Upstream commit 0df12a01f4857495816b05f048c4c31439446e35 ]
+
+We can currently sometimes get "RXS timed out" errors and "EOT timed out"
+errors with spi transfers.
+
+These errors can be made easy to reproduce by reading the cpcap iio
+values in a loop while keeping the CPUs busy by also reading /dev/urandom.
+
+The "RXS timed out" errors we can fix by adding spi-cpol and spi-cpha
+in addition to the spi-cs-high property we already have.
+
+The "EOT timed out" errors we can fix by increasing the spi clock rate
+to 9.6 MHz. Looks similar MC13783 PMIC says it works at spi clock rates
+up to 20 MHz, so let's assume we can pick any rate up to 20 MHz also
+for cpcap.

+
+[ Upstream commit a05caf9e62a85d12da27e814ac13195f4683f21c ]
+
+The Acer S1003 has proper DMI strings for sys-vendor and product-name,
+so we do not need to match by BIOS-date.
+
+This means that the Acer S1003 can use the generic lcd800x1280_rightside_up
+drm_dmi_panel_orientation_data struct which is also used by other quirks.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+[ Upstream commit 11425c4519e2c974a100fc984867046d905b9380 ]
+
+ttm_bo_add_move_fence() invokes dma_fence_get(), which returns a
+reference of the specified dma_fence object to "fence" with increased
+refcnt.
+
+When ttm_bo_add_move_fence() returns, local variable "fence" becomes
+invalid, so the refcount should be decreased to keep refcount balanced.
+
+The reference counting issue happens in one exception handling path of
+ttm_bo_add_move_fence(). When no_wait_gpu flag is equals to true, the
+function forgets to decrease the refcnt increased by dma_fence_get(),
+causing a refcnt leak.
+
+Fix this issue by calling dma_fence_put() when no_wait_gpu flag is
+equals to true.

+Subject: gpu: host1x: Detach driver on unregister
+
+From: Thierry Reding <treding@nvidia.com>
+
+[ Upstream commit d9a0a05bf8c76e6dc79230669a8b5d685b168c30 ]
+
+Currently when a host1x device driver is unregistered, it is not
+detached from the host1x controller, which means that the device
+will stay around and when the driver is registered again, it may
+bind to the old, stale device rather than the new one that was
+created from scratch upon driver registration. This in turn can
+cause various weird crashes within the driver core because it is
+confronted with a device that was already deleted.
+
+Fix this by detaching the driver from the host1x controller when
+it is unregistered. This ensures that the deleted device also is
+no longer present in the device list that drivers will bind to.

+From: Rajat Jain <rajatja@google.com>
+
+[ Upstream commit 67e8a5b18d41af9298db5c17193f671f235cce01 ]
+
+Currently, an external malicious PCI device can masquerade the VID:PID
+of faulty gfx devices, and thus apply iommu quirks to effectively
+disable the IOMMU restrictions for itself.
+
+Thus we need to ensure that the device we are applying quirks to, is
+indeed an internal trusted device.

+
+From: Sascha Hauer <s.hauer@pengutronix.de>
+
+[ Upstream commit 1a642ca7f38992b086101fe204a1ae3c90ed8016 ]
+
+The older SoCs like Armada XP support a 2500BaseX mode in the datasheets
+referred to as DR-SGMII (Double rated SGMII) or HS-SGMII (High Speed
+SGMII). This is an upclocked 1000BaseX mode, thus
+PHY_INTERFACE_MODE_2500BASEX is the appropriate mode define for it.
+adding support for it merely means writing the correct magic value into
+the MVNETA_SERDES_CFG register.

+Subject: net: ethernet: mvneta: Fix Serdes configuration for SoCs without
+ comphy
+
+From: Sascha Hauer <s.hauer@pengutronix.de>
+
+[ Upstream commit b4748553f53f2971e07d2619f13d461daac0f3bb ]
+
+The MVNETA_SERDES_CFG register is only available on older SoCs like the
+Armada XP. On newer SoCs like the Armada 38x the fields are moved to
+comphy. This patch moves the writes to this register next to the comphy
+initialization, so that depending on the SoC either comphy or
+MVNETA_SERDES_CFG is configured.
+With this we no longer write to the MVNETA_SERDES_CFG on SoCs where it
+doesn't exist.

+The completion vector index that is given during CQ creation can't
+exceed the number of support vectors by the underlying RDMA device. This
+violation currently can accure, for example, in case one will try to
+connect with N regular read/write queues and M poll queues and the sum
+of N + M > num_supported_vectors. This will lead to failure in establish
+a connection to remote target. Instead, in that case, share a completion
+vector between queues.

+Subject: regmap: fix alignment issue
+
+From: Jens Thoms Toerring <jt@toerring.de>
+
+[ Upstream commit 53d860952c8215cf9ae1ea33409c8cb71ad6ad3d ]
+
+The assembly and disassembly of data to be sent to or received from
+a device invoke functions regmap_format_XX() and regmap_parse_XX()
+that extract or insert data items from or into a buffer, using
+assignments. In some cases the functions are called with a buffer
+pointer with an odd address. On architectures with strict alignment
+requirements this can result in a kernel crash. The assignments
+have been replaced by functions that take alignment into account.

+
+From: Vasily Gorbik <gor@linux.ibm.com>
+
+[ Upstream commit 998f5bbe3dbdab81c1cfb1aef7c3892f5d24f6c7 ]
+
+Currently if early_pgm_check_handler is called it ends up in pgm check
+loop. The problem is that early_pgm_check_handler is instrumented by
+KASAN but executed without DAT flag enabled which leads to addressing
+exception when KASAN checks try to access shadow memory.
+
+Fix that by executing early handlers with DAT flag on under KASAN as
+expected.

+Subject: sched/core: Check cpus_mask, not cpus_ptr in
+ __set_cpus_allowed_ptr(), to fix mask corruption
+
+From: Scott Wood <swood@redhat.com>
+
+[ Upstream commit fd844ba9ae59b51e34e77105d79f8eca780b3bd6 ]
+
+This function is concerned with the long-term CPU mask, not the
+transitory mask the task might have while migrate disabled.  Before
+this patch, if a task was migrate-disabled at the time
+__set_cpus_allowed_ptr() was called, and the new mask happened to be
+equal to the CPU that the task was running on, then the mask update
+would be lost.

+Subject: scsi: mptscsih: Fix read sense data size
+
+From: Tomas Henzl <thenzl@redhat.com>
+
+[ Upstream commit afe89f115e84edbc76d316759e206580a06c6973 ]
+
+The sense data buffer in sense_buf_pool is allocated with size of
+MPT_SENSE_BUFFER_ALLOC(64) (multiplied by req_depth) while SNS_LEN(sc)(96)
+is used when reading the data.  That may lead to a read from unallocated
+area, sometimes from another (unallocated) page.  To fix this, limit the
+read size to MPT_SENSE_BUFFER_ALLOC.
