2021-12-25mm: delete unsafe BUG from page_cache_add_speculative()Hugh Dickins
It is not easily reproducible, but on 5.16-rc I have several times hit the VM_BUG_ON_PAGE(PageTail(page), page) in page_cache_add_speculative(): usually from filemap_get_read_batch() for an ext4 read, yesterday from next_uptodate_page() from filemap_map_pages() for a shmem fault. That BUG used to be placed where page_ref_add_unless() had succeeded, but now it is placed before folio_ref_add_unless() is attempted: that is not safe, since it is only the acquired reference which makes the page safe from racing THP collapse or split. We could keep the BUG, checking PageTail only when folio_ref_try_add_rcu() has succeeded; but I don't think it adds much value - just delete it.

This mainly implements detection of these devices and will allow secondary drivers to work on such machines. The identification is DMI-based with a vendor specific way to tell them apart in a reliable way. Drivers for LEDs and Watchdogs will follow to make use of that platform detection.

2021-12-22scsi: block: pm: Always set request queue runtime active in ↵Alan Stern
blk_post_runtime_resume() John Garry reported a deadlock that occurs when trying to access a runtime-suspended SATA device. For obscure reasons, the rescan procedure causes the link to be hard-reset, which disconnects the device. The rescan tries to carry out a runtime resume when accessing the device. scsi_rescan_device() holds the SCSI device lock and won't release it until it can put commands onto the device's block queue. This can't happen until the queue is successfully runtime-resumed or the device is unregistered. But the runtime resume fails because the device is disconnected, and __scsi_remove_device() can't do the unregistration because it can't get the device lock. The best way to resolve this deadlock appears to be to allow the block queue to start running again even after an unsuccessful runtime resume. The idea is that the driver or the SCSI error handler will need to be able to use the queue to resolve the runtime resume failure. This patch removes the err argument to blk_post_runtime_resume() and makes the routine act as though the resume was successful always. This fixes the deadlock.

2021-12-23Merge tag 'drm/tegra/for-5.17-rc1' of ↵Dave Airlie
https://gitlab.freedesktop.org/drm/tegra into drm-next drm/tegra: Changes for v5.17-rc1 This contains a fairly large rework that makes the buffer objects behave more according to what the DMA-BUF infrastructure expects. A buffer object cache is implemented on top of that to make certain operations such as page-flipping more efficient by avoiding needless map/unmap operations. This in turn is useful to implement asynchronous commits to support legacy cursor updates. Another fairly big addition is the NVDEC driver. This uses the updated UABI introduced in v5.15-rc1 to provide access to the video decode engines found on Tegra210 and later. This also includes some power management improvements that are useful on older devices in particular because they, together with a bunch of other changes across the kernel, allow the system to scale down frequency and voltages when mostly idle and prevent these devices from becoming excessively hot. The remainder of these changes is an assortment of cleanups and minor fixes.

This bug introduced by commit b261dba2fdb2 ("arm64: kdump: Remove custom linux,usable-memory-range handling"), which moves memblock_cap_memory_range() to fdt, but it breaches the rules that memblock_cap_memory_range() should come after memblock_add() etc as said in commit e888fa7bb882 ("memblock: Check memory add/cap ordering"). As a consequence, the virtual address set up by copy_oldmem_page() does not bail out from the test of virt_addr_valid() in check_heap_object(), and finally hits the BUG_ON(). Since memblock allocator has no idea about when the memblock is fully populated, while efi_init() is aware, so tackling this issue by calling the interface early_init_dt_check_for_usable_mem_range() exposed by of/fdt.

ID and chip specific info table. * xilinx,ams - New generic firmware function fwnode_iomap() as used in this driver. - New driver and bindings for this ADC and on-chip sensors as found in various Xilinx devices. Core * Introduced IIO_VAL_INT_64 which uses val and val2 in IIO callbacks to form a 64 bit integer when higher precision needed. * Allow IIO_ENUM_AVAILABLE to be used with different shared values. * Fix a long term issue with scheduling whilst atomic when iio_trig_poll() is called but no trigger consumers are actually enabled and hence the trigger may be reenabled from the interrupt handler. Seen in the wild on the tsc2046. * Mark iio_device_type const. * buffer: Use a separate index variable to simplify code. * buffer-dma: Clear out unused struct iio_buffer_block * buffer-dmaengine: Switch to cheaper round_down() as power of 2 values. Tests/tools * format_value - Check against NULL returns from allocations in tests. - Add IIO_VAL_INT_64 test case. * event_monitor - Flush the output after event to given more consistent latency when tool output piped to other programs. Driver Features * axp20x - Add support for NTC thermistor channel and document TS pin binding. * arm,scmi - Add reading of raw channel values (using IIO_VAL_INT_64) * liteon,ltr501 - Add proximity-near-level support and dt-binding. Tree wide cleanup * Remove no-op trigger ops from multiple drivers. * Stop using dev_get_drvdata() on the iio_dev->dev in various drivers and then stop assigning it to allow this to be used for other purposes. We can always get to the indio_dev using dev_to_iio_dev() which is a container_of() based approach.

2021-12-20net: skip virtio_net_hdr_set_proto if protocol already setWillem de Bruijn
virtio_net_hdr_set_proto infers skb->protocol from the virtio_net_hdr gso_type, to avoid packets getting dropped for lack of a proto type. Its protocol choice is a guess, especially in the case of UFO, where the single VIRTIO_NET_HDR_GSO_UDP label covers both UFOv4 and UFOv6. Skip this best effort if the field is already initialized. Whether explicitly from userspace, or implicitly based on an earlier call to dev_parse_header_protocol (which is more robust, but was introduced after this patch).

Unlike TCP, UDP does not have separate types for IPv4 and IPv6. Type VIRTIO_NET_HDR_GSO_UDP is guessed to be IPv4/UDP.

In Isolation VM with AMD SEV, bounce buffer needs to be accessed via extra address space which is above shared_gpa_boundary (E.G 39 bit address line) reported by Hyper-V CPUID ISOLATION_CONFIG. The access physical address will be original physical address + shared_gpa_boundary. The shared_gpa_boundary in the AMD SEV SNP spec is called virtual top of memory(vTOM). Memory addresses below vTOM are automatically treated as private while memory above vTOM is treated as shared. Expose swiotlb_unencrypted_base for platforms to set unencrypted memory base offset and platform calls swiotlb_update_mem_attributes() to remap swiotlb mem to unencrypted address space. memremap() can not be called in the early stage and so put remapping code into swiotlb_update_mem_attributes().

2021-12-20iommu: Move flush queue data into iommu_dma_cookieRobin Murphy
Complete the move into iommu-dma by refactoring the flush queues themselves to belong to the DMA cookie rather than the IOVA domain. The refactoring may as well extend to some minor cosmetic aspects too, to help us stay one step ahead of the style police.

2021-12-20iommu/vt-d: Use put_pages_listMatthew Wilcox (Oracle)
page->freelist is for the use of slab. We already have the ability to free a list of pages in the core mm, but it requires the use of a list_head and for the pages to be chained together through page->lru. Switch the Intel IOMMU and IOVA code over to using free_pages_list().

2021-12-20iommu/iova: Squash flush_cb abstractionRobin Murphy
Once again, with iommu-dma now being the only flush queue user, we no longer need the extra level of indirection through flush_cb. Squash that and let the flush queue code call the domain method directly. This does mean temporarily having to carry an additional copy of the IOMMU domain pointer around instead, but only until a later patch untangles it again.

2021-12-20iommu/iova: Squash entry_dtor abstractionRobin Murphy
All flush queues are driven by iommu-dma now, so there is no need to abstract entry_dtor or its data any more. Squash the now-canonical implementation directly into the IOVA code to get it out of the way.
