2021-04-07time: Add mechanism to recognize clocksource in time_get_snapshotThomas Gleixner
System time snapshots are not conveying information about the current clocksource which was used, but callers like the PTP KVM guest implementation have the requirement to evaluate the clocksource type to select the appropriate mechanism. Introduce a clocksource id field in struct clocksource which is by default set to CSID_GENERIC (0). Clocksource implementations can set that field to a value which allows to identify the clocksource. Store the clocksource id of the current clocksource in the system_time_snapshot so callers can evaluate which clocksource was used to take the snapshot and act accordingly.

2021-04-07iommu: Add a page fault handlerJean-Philippe Brucker
Some systems allow devices to handle I/O Page Faults in the core mm. For example systems implementing the PCIe PRI extension or Arm SMMU stall model. Infrastructure for reporting these recoverable page faults was added to the IOMMU core by commit 0c830e6b3282 ("iommu: Introduce device fault report API"). Add a page fault handler for host SVA. IOMMU driver can now instantiate several fault workqueues and link them to IOPF-capable devices. Drivers can choose between a single global workqueue, one per IOMMU device, one per low-level fault queue, one per domain, etc. When it receives a fault event, most commonly in an IRQ handler, the IOMMU driver reports the fault using iommu_report_device_fault(), which calls the registered handler. The page fault handler then calls the mm fault handler, and reports either success or failure with iommu_page_response(). After the handler succeeds, the hardware retries the access. The iopf_param pointer could be embedded into iommu_fault_param. But putting iopf_param into the iommu_param structure allows us not to care about ordering between calls to iopf_queue_add_device() and iommu_register_device_fault_handler().

2021-04-07iommu: Separate IOMMU_DEV_FEAT_IOPF from IOMMU_DEV_FEAT_SVAJean-Philippe Brucker
Some devices manage I/O Page Faults (IOPF) themselves instead of relying on PCIe PRI or Arm SMMU stall. Allow their drivers to enable SVA without mandating IOMMU-managed IOPF. The other device drivers now need to first enable IOMMU_DEV_FEAT_IOPF before enabling IOMMU_DEV_FEAT_SVA. Enabling IOMMU_DEV_FEAT_IOPF on its own doesn't have any effect visible to the device driver, it is used in combination with other features.

2021-04-07iommu: Fix a boundary issue to avoid performance dropXiang Chen
After the change of patch ("iommu: Switch gather->end to the inclusive end"), the performace drops from 1600+K IOPS to 1200K in our kunpeng ARM64 platform. We find that the range [start1, end1) actually is joint from the range [end1, end2), but it is considered as disjoint after the change, so it needs more times of TLB sync, and spends more time on it. So fix the boundary issue to avoid performance drop.

2021-04-07mtd: rawnand: Add support for secure regions in NAND memoryManivannan Sadhasivam
On a typical end product, a vendor may choose to secure some regions in the NAND memory which are supposed to stay intact between FW upgrades. The access to those regions will be blocked by a secure element like Trustzone. So the normal world software like Linux kernel should not touch these regions (including reading). The regions are declared using a NAND chip DT property, "secure-regions". So let's make use of this property in the raw NAND core and skip access to the secure regions present in a system.

2021-04-07iio:event: Add timeout event info typeJonathan Cameron
For adaptive threshold events, the current value is compared with a (typically) low pass filtered version of the same signal that slowly tracks large scale changes. However, sometimes a step change can result in a large lag before the low pass filtered version begins to track the signal again. Timeouts can be used to made an instantaneous 'correction'. Documentation of this attribute is added in a later patch.
