[ Upstream commit 6ad16b78 ] EC_MKBP_EVENT_SENSOR_FIFO events can be triggered for a variety of reasons, and there are very few cases in which they should be treated as wakeup interrupts (particularly, when a certain MOTIONSENSE_MODULE_FLAG_* is set, but this is not even supported in the mainline cros_ec_sensor driver yet). Most of the time, they are benign sensor readings. In any case, the top-level cros_ec device doesn't know enough to determine that they should wake the system, and so it should not report the event. This would be the job of the cros_ec_sensors driver to parse. This patch adds checks to cros_ec_get_next_event() such that it doesn't signal 'wakeup' for events of type EC_MKBP_EVENT_SENSOR_FIFO. This patch is particularly relevant on devices like Scarlet (Rockchip RK3399 tablet, known as Acer Chromebook Tab 10), where the EC firmware reports sensor events much more frequently. This was causing /sys/power/wakeup_count to increase very frequently, often needlessly interrupting our ability to suspend the system. Signed-off-by:

[ Upstream commit 5ec17af7 ] The Intel EG20T Platform Controller Hub used on the MIPS Boston development board supports prefetching memory to optimize DMA transfers. Unfortunately for unknown reasons this doesn't work well with some MIPS CPUs such as the P6600, particularly when using an I/O Coherence Unit (IOCU) to provide cache-coherent DMA. In these systems it is common for DMA data to be lost, resulting in broken access to EG20T devices such as the MMC or SATA controllers. Support for a DT property to configure the prefetching was added a while back by commit 549ce8f1 ("misc: pch_phub: Read prefetch value from device tree if passed") but we never added the DT snippet to make use of it. Add that now in order to disable the prefetching & fix DMA on the affected systems. Signed-off-by:

[ Upstream commit 0560054d ] For the YUV conversion to work properly, ->x_scaling[1] should never be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE into VC4_SCALING_PPF when that happens. The old ->x_scaling[0] adjustment is dropped as I couldn't find any mention to this constraint in the spec and it's proven to be unnecessary (I tested various multi-planar YUV formats with scaling disabled, and all of them worked fine without this adjustment).

[ Upstream commit 0a6a40c2 ] In the "aes-fixed-time" AES implementation, disable interrupts while accessing the S-box, in order to make cache-timing attacks more difficult. Previously it was possible for the CPU to be interrupted while the S-box was loaded into L1 cache, potentially evicting the cachelines and causing later table lookups to be time-variant. In tests I did on x86 and ARM, this doesn't affect performance significantly. Responsiveness is potentially a concern, but interrupts are only disabled for a single AES block. Note that even after this change, the implementation still isn't necessarily guaranteed to be constant-time; see https://cr.yp.to/antiforgery/cachetiming-20050414.pdf for a discussion of the many difficulties involved in writing truly constant-time AES software. But it's valuable to make such attacks more difficult. Reviewed-by:

[ Upstream commit 30e196ca ] After a LOGO in response to an ABTS timeout, a PLOGI wasn't issued to re-establish the login. An nlp_type check in the LOGO completion handler failed to restart discovery for NVME targets. Revised the nlp_type check for NVME as well as SCSI. While reviewing the LOGO handling a few other issues were seen and were addressed: - Better lock synchronization around ndlp data types - When the ABTS times out, unregister the RPI before sending the LOGO so that all local exchange contexts are cleared and nothing received while awaiting LOGO/PLOGI handling will be accepted. - LOGO handling optimized to: Wait only R_A_TOV for a response. It doesn't need to be retried on timeout. If there wasn't a response, a PLOGI will be sent, thus an implicit logout applies as well when the other port sees it. If there is a response, any kind of response is considered "good" and the XRI quarantined for a exchange qualifier window. - PLOGI is issued as soon a LOGO state is resolved. Signed-off-by:

[ Upstream commit 819bec35 ] Prevent possible race by parallel threads between ipu_image_convert_run() and ipu_image_convert_unprepare(). This involves setting ctx->aborting to true unconditionally so that no new job runs can be queued during unprepare, and holding the ctx->aborting flag until the context is freed. Note that the "normal" ipu_image_convert_abort() case (e.g. not during context unprepare) should clear the ctx->aborting flag after aborting any active run and clearing the context's pending queue. This is because it should be possible to continue to use the conversion context and queue more runs after an abort. Signed-off-by:

[ Upstream commit b8259219 ] If the number of NUMA nodes exceeds the number of MSI/MSI-X interrupts which are allocated for a device, the interrupt affinity spreading code fails to spread them across all nodes. The reason is, that the spreading code starts from node 0 and continues up to the number of interrupts requested for allocation. This leaves the nodes past the last interrupt unused. This results in interrupt concentration on the first nodes which violates the assumption of the block layer that all nodes are covered evenly. As a consequence the NUMA nodes above the number of interrupts are all assigned to hardware queue 0 and therefore NUMA node 0, which results in bad performance and has CPU hotplug implications, because queue 0 gets shut down when the last CPU of node 0 is offlined. Go over all NUMA nodes and assign them round-robin to all requested interrupts to solve this. [ tglx: Massaged changelog ] Signed-off-by:

[ Upstream commit 18534df4 ] gpiod_request_commit() copies the pointer to the label passed as an argument only to be used later. But there's a chance the caller could immediately free the passed string(e.g., local variable). This could trigger a use after free when we use gpio label(e.g., gpiochip_unlock_as_irq(), gpiochip_is_requested()). To be on the safe side: duplicate the string with kstrdup_const() so that if an unaware user passes an address to a stack-allocated buffer, we won't get the arbitrary label.

[ Upstream commit 3c7b30f7 ] The BCM2835 pinctrl driver acquires a spinlock in its ->irq_enable, ->irq_disable and ->irq_set_type callbacks. Spinlocks become sleeping locks with CONFIG_PREEMPT_RT_FULL=y, therefore invocation of one of the callbacks in atomic context may cause a hard lockup if at least two GPIO pins in the same bank are used as interrupts. The issue doesn't occur with just a single interrupt pin per bank because the lock is never contended. I'm experiencing such lockups with GPIO 8 and 28 used as level-triggered interrupts, i.e. with ->irq_disable being invoked on reception of every IRQ. The critical section protected by the spinlock is very small (one bitop and one RMW of an MMIO register), hence converting to a raw spinlock seems a better trade-off than converting the driver to threaded IRQ handling (which would increase latency to handle an interrupt).

commit a66d9724 upstream. Initially we bumped into problem with 32-bit aligned atomic64_t on ARC, see [1]. And then during quite lengthly discussion Peter Z. mentioned ARCH_KMALLOC_MINALIGN which IMHO makes perfect sense. If allocation is done by plain kmalloc() obtained buffer will be ARCH_KMALLOC_MINALIGN aligned and then why buffer obtained via devm_kmalloc() should have any other alignment? This way we at least get the same behavior for both types of allocation.

commit 483cbbed upstream. This fixes the case when md array assembly fails because of raid cache recovery unable to allocate a stripe, despite attempts to replay stripes and increase cache size. This happens because stripes released by r5c_recovery_replay_stripes and raid5_set_cache_size don't become available for allocation immediately. Released stripes first are placed on conf->released_stripes list and require md thread to merge them on conf->inactive_list before they can be allocated. Patch allows final allocation attempt during cache recovery to wait for new stripes to become availabe for allocation.
