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.

https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: 1st set of IIO new device support, features and cleanup for 5.17 Includes some fixes that were either late breaking, low priority or complex enough to not be good to rush in late in the cycle. Tree rebased today to fix up some trivial issues + pull in a fix that was previously on the fixes-togreg branch. Vast majority have been in linux-next for some time now. New device support * adi,ad7293 - New driver and bindings for this Power Amplifier drain current controller. A complex device with various related monitoring functions. * adi,ad75513R - New driver and bindings for this combined ADC and DAC device. - A few follow up fixes. * adi,admv8818 - New driver (and type) for this 2-18GHz filter device. Includes bindings and ABI documentation to allow clk_notifier based auto adjustment of the filters in appropriate applications. * liteon,ltr501 - Support for the ltr303. 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. Also cleanup up some related unnecessary convoluted cases. - atmel,at91-sam5d2 - nxp,imx7d - meas,ms5611 - st,st_sensors * Where available (or easy to introduce) use the scan_type.* values in place of a second copy for read_raw and similar paths. - adi,ad7266 - bosch,bma220 - fsl,mac3110 - fsl,mma7455 - fsl,mpl3115 - kionix,kcjk-1013 - sensortek,stk8ba50 - sensortek,stk8312 - ti,adc12138 - ti,ads1015 - vti,sca3000 - xilinx,xadc-core * Switch drives over to generic firmware properties including appropriate header changes to avoid including of.h - Various DACs had false CONFIG_OF dependencies. - dpot-dac - envelope-detector - adi,ad5755 - adi,ad5758 - capella,cm3605 - maxim,max9611 - microchip,mcp41010 - microchip,mcp3911 - ti,adc12138 * Trivial clang warning fixes for W=1 warnings. Driver specific cleanup and minor fixes * adi,ad7606 - Comment fixes. * ams,ad3935 - Drop pointless cast to the same type. * atmel,at91-sama5d2 - Fix wrong cast of iio_dev->dev to platform_device that happened to be harmless. * fsl,mma7660 - Stop i2c remove() function returning an error code. Part of a rework to eventually stop returning anything from these. * fsl,mma8452 - Use correct type for local irqreturn_t. * nxp,imx8mq - Maintainer email address update. * nxp,lpc18xx_adc - Ensure clk_prepare_enable() called before clk_get_rate(). - Switch of.h for mod_devicetable.h to reflect no of specific functions, just the id table. * renesas,rzg2l - Drop a dev_err() that just duplicates error printed in platform_get_irq() * sgx,vz89x - Drop pointless cast. * st,lsm6dsx - Make it possible to disable the sensorhub from DT to avoid a corner case where the address of a slave device many be accidentally modified. * st,stm32-adc - Stop leaking an of_node in an error path. * st,stmp2 - Avoid wrong sized type for bit field which could result in over-reading (harmless). Precursor to enabling -Warray-bounds. * ti,adc081c - Put back some ACPI support for non standards compliant ADC081C ID because it is known to be in the wild on some Aaeon boards. * ti,ads8688 - Cleanup redundant local ret variable assignment. * ti,ina2xx-adc - Use helper macro kthread_run() to replace some boilerplate. - Avoid double reference counting. - Drop pointless cast. * xilinx,xadc - Make the IRQ optional as not always wired to the host system. * tag 'iio-for-5.17a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (103 commits) iio: adc: ti-adc081c: Partial revert of removal of ACPI IDs iio:addac:ad74413r: Fix uninitialized ret in a path that won't be hit.

2021-12-22asm-generic: introduce io_stop_wc() and add implementation for ARM64Xiongfeng Wang
For memory accesses with write-combining attributes (e.g. those returned by ioremap_wc()), the CPU may wait for prior accesses to be merged with subsequent ones. But in some situation, such wait is bad for the performance. We introduce io_stop_wc() to prevent the merging of write-combining memory accesses before this macro with those after it. We add implementation for ARM64 using DGH instruction and provide NOP implementation for other architectures.

This patch introduces a new helper routine - fwnode_iomap(), which allows to map the memory mapped IO for a given device node. This implementation does not cover the ACPI case and may be expanded in the future. The main purpose here is to be able to develop resource provider agnostic drivers.

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).

2021-12-20net: accept UFOv6 packages in virtio_net_hdr_to_skbWillem de Bruijn
Skb with skb->protocol 0 at the time of virtio_net_hdr_to_skb may have a protocol inferred from virtio_net_hdr with virtio_net_hdr_set_proto. Unlike TCP, UDP does not have separate types for IPv4 and IPv6. Type VIRTIO_NET_HDR_GSO_UDP is guessed to be IPv4/UDP. As of the below commit, UFOv6 packets are dropped due to not matching the protocol as obtained from dev_parse_header_protocol. Invert the test to take that L2 protocol field as starting point and pass both UFOv4 and UFOv6 for VIRTIO_NET_HDR_GSO_UDP.

2021-12-20inet: fully convert sk->sk_rx_dst to RCU rulesEric Dumazet
syzbot reported various issues around early demux, one being included in this changelog [1] sk->sk_rx_dst is using RCU protection without clearly documenting it. And following sequences in tcp_v4_do_rcv()/tcp_v6_do_rcv() are not following standard RCU rules. [a] dst_release(dst); [b] sk->sk_rx_dst = NULL; They look wrong because a delete operation of RCU protected pointer is supposed to clear the pointer before the call_rcu()/synchronize_rcu() guarding actual memory freeing. In some cases indeed, dst could be freed before [b] is done. We could cheat by clearing sk_rx_dst before calling dst_release(), but this seems the right time to stick to standard RCU annotations and debugging facilities.

2021-12-20swiotlb: Add swiotlb bounce buffer remap function for HV IVMTianyu Lan
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().

git://git.kernel.org/pub/scm/linux/kernel/git/krzk/linux into arm/drivers Samsung SoC drivers changes for v5.17 1. Exynos ChipID: add Exynos7885 support. 2. Exynos PMU: add Exynos850 support. 3. Minor bindings cleanup. 4. Add Exynos USIv2 (Universal Serial Interface) driver. The USI block is a shared IP block between I2C, UART/serial and SPI. Basically one has to choose which feature the USI block will support and later the regular I2C/serial/SPI driver will bind and work. This merges also one commit with dt-binding headers from my dts64 pull request. Together with a future serial driver change, this will break the ABI. Affected: Serial on ExynosAutov9 SADK and out-of-tree ExynosAutov9 boards Why: To properly and efficiently support the USI with new hierarchy of USI-{serial,SPI,I2C} devicetree nodes. Rationale: Recently added serial and USI support was short-sighted and did not allow to smooth support of other features (SPI and I2C). Adding support for USI-SPI and USI-I2C would effect in code duplication. Adding support for different USI versions (currently supported is USIv2 but support for v1 is planned) would cause even more code duplication and create a solution difficult to maintain. Since USI-serial and ExynosAutov9 have been added recently, are considered fresh development features and there are no supported products using them, the code/solution is being refactored in non-backwards compatible way. The compatibility is not broken yet. It will be when serial driver changes are accepted.

2021-12-20rfkill: allow to get the software rfkill stateEmmanuel Grumbach
iwlwifi needs to be able to differentiate between the software rfkill state and the hardware rfkill state. The reason for this is that iwlwifi needs to notify any change in the software rfkill state even when it doesn't own the device (which means even when the hardware rfkill is asserted). In order to be able to know the software rfkill when the host does not own the device, iwlwifi needs to be able to ask the state of the software rfkill ignoring the state of the hardware rfkill.

2021-12-20nl82011: clarify interface combinations wrt. channelsJohannes Berg
Thinking about MLD (Draft 802.11be) now, it's clear that we'll have new limitations where different stations (or links) must be on _different_ channels (or in different frequency ranges even.) Clarify that the current limit of multiple channels is a maximum and the same one is OK.

2021-12-20nl80211: Add support to offload SA Query procedures for AP SME deviceVeerendranath Jakkam
Add a flag attribute to use in ap settings to indicate userspace supports offloading of SA Query procedures to driver. Also add AP SME device feature flag to advertise that the SA Query procedures offloaded to driver when userspace indicates support for offloading of SA Query procedures. Driver handles SA Query procedures in driver's SME it self and skip sending SA Query request or response frames to userspace when userspace indicates support for SA Query procedures offload. But if userspace doesn't advertise support for SA Query procedures offload driver shall not offload SA Query procedures handling. Also userspace with SA Query procedures offload capability shall skip SA Query specific validations when driver indicates support for handling SA Query procedures.
