* remoteproc: qcom: q6v5-pil: fix modem hang on SDM845 after axis2 clk unvoteSibi Sankar2018-09-261-1/+0
| | | | | | | | | | | | | | | | | | | | | [ Upstream commit 7cbb540a3a68e4d4a8bef2d9451afb1635b5d2d3 ] GCC_MSS_AXIS2 clock is used for disabling boot IMEM (a part of AP boot up). With Boot IMEM disable now a part TZ/ATF, AXIS2 clock is no longer required post AP boot up and expected to remain untouched. However if the clock is turned ON after Q6 is brought out of reset and later turned off, it results in modem hang. When Q6 attempts a power collapse the internal handshaking to check if AXIS2 is idle never goes through since it is turned off preventing the RSC from getting triggered, leaving modem in a funky state. Hence removing AXIS2 clk enable/disable from the driver.

* rcutorture: Use monotonic timestamp for stall detectionArnd Bergmann2018-09-261-2/+3
| | | | | | | | | | | | | | | | | | | [ Upstream commit 622be33fcbc93e9b672b99ed338369eb5e843ac3 ] The get_seconds() call is deprecated because it overflows on 32-bit architectures. The algorithm in rcu_torture_stall() can deal with the overflow, but another problem here is that using a CLOCK_REALTIME stamp can lead to a false-positive stall warning when a settimeofday() happens concurrently. Using ktime_get_seconds() instead avoids those issues and will never overflow. The added cast to 'unsigned long' however is necessary to make ULONG_CMP_LT() work correctly.

* sched/fair: Fix util_avg of new tasks for asymmetric systemsQuentin Perret2018-09-261-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 8fe5c5a937d0f4e84221631833a2718afde52285 ] When a new task wakes-up for the first time, its initial utilization is set to half of the spare capacity of its CPU. The current implementation of post_init_entity_util_avg() uses SCHED_CAPACITY_SCALE directly as a capacity reference. As a result, on a big.LITTLE system, a new task waking up on an idle little CPU will be given ~512 of util_avg, even if the CPU's capacity is significantly less than that. Fix this by computing the spare capacity with arch_scale_cpu_capacity().

* drm/nouveau: tegra: Detach from ARM DMA/IOMMU mappingThierry Reding2018-09-261-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit b59fb482b52269977ee5de205308e5b236a03917 ] Depending on the kernel configuration, early ARM architecture setup code may have attached the GPU to a DMA/IOMMU mapping that transparently uses the IOMMU to back the DMA API. Tegra requires special handling for IOMMU backed buffers (a special bit in the GPU's MMU page tables indicates the memory path to take: via the SMMU or directly to the memory controller). Transparently backing DMA memory with an IOMMU prevents Nouveau from properly handling such memory accesses and causes memory access faults. As a side-note: buffers other than those allocated in instance memory don't need to be physically contiguous from the GPU's perspective since the GPU can map them into contiguous buffers using its own MMU. Mapping these buffers through the IOMMU is unnecessary and will even lead to performance degradation because of the additional translation. One exception to this are compressible buffers which need large pages. In order to enable these large pages, multiple small pages will have to be combined into one large (I/O virtually contiguous) mapping via the IOMMU. However, that is a topic outside the scope of this fix and isn't currently supported. An implementation will want to explicitly create these large pages in the Nouveau driver, so detaching from a DMA/IOMMU mapping would still be required.

Make sure that the corresponding dma mask is correctly configured. Context: when enabling smmu on these chips the following problem is encountered: the smmu input address size is 48 bits so the dma mappings for sdhci end up 48-bit wide. However, on these chips sdhci only use 40-bits of that address size when doing dma. So you end up with a 48-bit address translation in smmu but the device generates transactions with clipped 40-bit addresses, thus smmu context faults are triggered.

When the user requests a rate using BOTHER and c_ospeed which the driver cannot set exactly, the driver can report back the actual baud rate using tty_termios_encode_baud_rate(). If this rate is close enough to a standard rate however, we could end up setting CIBAUD to a Bfoo value despite the user having left it unset. This in turn could lead to an unexpected input rate being set on subsequent termios updates.

If we end up connecting "TX" incorrectly, it can result in components not being started, causing no audio output. Since the I2S and S/PDIF streams now have different names, we can't use a static route at component level to describe the relationship, so arrange to dynamically create the route when the DAI driver is probed.
