2020-10-01iommu/vt-d: Check UAPI data processed by IOMMU coreJacob Pan
IOMMU generic layer already does sanity checks on UAPI data for version match and argsz range based on generic information.

2020-10-01iommu/uapi: Handle data and argsz filled by usersJacob Pan
IOMMU user APIs are responsible for processing user data. This patch changes the interface such that user pointers can be passed into IOMMU code directly. Separate kernel APIs without user pointers are introduced for in-kernel users of the UAPI functionality. IOMMU UAPI data has a user filled argsz field which indicates the data length of the structure. User data is not trusted, argsz must be validated based on the current kernel data size, mandatory data size, and feature flags. User data may also be extended, resulting in possible argsz increase. Backward compatibility is ensured based on size and flags (or the functional equivalent fields) checking. This patch adds sanity checks in the IOMMU layer. In addition to argsz, reserved/unused fields in padding, flags, and version are also checked.

2020-10-01iommu/uapi: Rename uapi functionsJacob Pan
User APIs such as iommu_sva_unbind_gpasid() may also be used by the kernel. Since we introduced user pointer to the UAPI functions, in-kernel callers cannot share the same APIs. In-kernel callers are also trusted, there is no need to validate the data. We plan to have two flavors of the same API functions, one called through ioctls, carrying a user pointer and one called directly with valid IOMMU UAPI structs. To differentiate both, let's rename existing functions with an iommu_uapi_ prefix.

2020-10-01iommu/uapi: Use named union for user dataJacob Pan
IOMMU UAPI data size is filled by the user space which must be validated by the kernel. To ensure backward compatibility, user data can only be extended by either re-purpose padding bytes or extend the variable sized union at the end. No size change is allowed before the union. Therefore, the minimum size is the offset of the union. To use offsetof() on the union, we must make it named.

2020-10-01xen/events: don't use chip_data for legacy IRQsJuergen Gross
Since commit c330fb1ddc0a ("XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information.") Xen is using the chip_data pointer for storing IRQ specific data. When running as a HVM domain this can result in problems for legacy IRQs, as those might use chip_data for their own purposes. Use a local array for this purpose in case of legacy IRQs, avoiding the double use.

2020-10-01iommu/amd: Fix the overwritten field in IVMD headerAdrian Huang
Commit 387caf0b759a ("iommu/amd: Treat per-device exclusion ranges as r/w unity-mapped regions") accidentally overwrites the 'flags' field in IVMD (struct ivmd_header) when the I/O virtualization memory definition is associated with the exclusion range entry. This leads to the corrupted IVMD table (incorrect checksum). The kdump kernel reports the invalid checksum: ACPI BIOS Warning (bug): Incorrect checksum in table [IVRS] - 0x5C, should be 0x60 (20200717/tbprint-177) AMD-Vi: [Firmware Bug]: IVRS invalid checksum Fix the above-mentioned issue by modifying the 'struct unity_map_entry' member instead of the IVMD header.

2020-10-01serial: max310x: rework RX interrupt handlingThomas Petazzoni
Currently, the RX interrupt logic uses the RXEMPTY interrupt, with the RXEMPTYINV bit set, which means we get an RX interrupt as soon as the RX FIFO is non-empty. However, with the MAX310X having a FIFO of 128 bytes, this makes very poor use of the FIFO: we trigger an interrupt as soon as the RX FIFO has one byte, which means a lot of interrupts, each only collecting a few bytes from the FIFO, causing a significant CPU load. Instead this commit relies on two other RX interrupt events: - MAX310X_IRQ_RXFIFO_BIT, which triggers when the RX FIFO has reached a certain threshold, which we define to be half of the FIFO size. This ensure we get an interrupt before the RX FIFO fills up. - MAX310X_LSR_RXTO_BIT, which triggers when the RX FIFO has received some bytes, and then no more bytes are received for a certain time. Arbitrarily, this time is defined to the time is takes to receive 4 characters. On a Microchip SAMA5D3 platform that is receiving 20 bytes every 16ms over one MAX310X UART, this patch has allowed to reduce the CPU consumption of the interrupt handler thread from ~25% to 6-7%.

Zoran is picky about jpeg data it accepts. At least it seems to not support COM and APPn. So until a way to filter data will be done, disable output.

2020-10-01gpio: pca953x: Correctly initialize registers 6 and 7 for PCA957xAndy Shevchenko
When driver has been converted to the bitmap API the non-bitmap functions started behaving differently on 32-bit BE architectures since the bytes in two consequent unsigned longs are in different order in comparison to byte array. Hence if the chip had had more than 32 lines the memset() call over it would have not set up upper lines correctly. Although it's currently a theoretical case (no supported chips of this type has 32+ lines), it's better to provide a clean code to avoid people thinking this is okay and potentially producing not fully working things.

2020-10-01gpio: pca953x: Use bitmap API over implicit GCC extensionAndy Shevchenko
In IRQ handler we have to clear bitmap before use. Currently the GCC extension has been used for that. For sake of the consistency switch to bitmap API. As expected bloat-o-meter shows no difference in the object size.
