2020-08-03Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linuxLinus Torvalds5-298/+72
Pull arm64 and cross-arch updates from Catalin Marinas: "Here's a slightly wider-spread set of updates for 5.9. Going outside the usual arch/arm64/ area is the removal of read_barrier_depends() series from Will and the MSI/IOMMU ID translation series from Lorenzo. The notable arm64 updates include ARMv8.4 TLBI range operations and translation level hint, time namespace support, and perf. Summary: - Removal of the tremendously unpopular read_barrier_depends() barrier, which is a NOP on all architectures apart from Alpha, in favour of allowing architectures to override READ_ONCE() and do whatever dance they need to do to ensure address dependencies provide LOAD -> LOAD/STORE ordering. This work also offers a potential solution if compilers are shown to convert LOAD -> LOAD address dependencies into control dependencies (e.g. under LTO), as weakly ordered architectures will effectively be able to upgrade READ_ONCE() to smp_load_acquire(). The latter case is not used yet, but will be discussed further at LPC. - Make the MSI/IOMMU input/output ID translation PCI agnostic, augment the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID bus-specific parameter and apply the resulting changes to the device ID space provided by the Freescale FSL bus. - arm64 support for TLBI range operations and translation table level hints (part of the ARMv8.4 architecture version). - Time namespace support for arm64. - Export the virtual and physical address sizes in vmcoreinfo for makedumpfile and crash utilities. - CPU feature handling cleanups and checks for programmer errors (overlapping bit-fields). - ACPI updates for arm64: disallow AML accesses to EFI code regions and kernel memory. - perf updates for arm64. - Miscellaneous fixes and cleanups, most notably PLT counting optimisation for module loading, recordmcount fix to ignore relocations other than R_AARCH64_CALL26, CMA areas reserved for gigantic pages on 16K and 64K configurations. - Trivial typos, duplicate words" Link: http://lkml.kernel.org/r/20200710165203.31284-1-will@kernel.org Link: http://lkml.kernel.org/r/20200619082013.13661-1-lorenzo.pieralisi@arm.com * tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: (82 commits) arm64: use IRQ_STACK_SIZE instead of THREAD_SIZE for irq stack arm64/mm: save memory access in check_and_switch_context() fast switch path arm64: sigcontext.h: delete duplicated word arm64: ptrace.h: delete duplicated word arm64: pgtable-hwdef.h: delete duplicated words bus: fsl-mc: Add ACPI support for fsl-mc bus/fsl-mc: Refactor the MSI domain creation in the DPRC driver of/irq: Make of_msi_map_rid() PCI bus agnostic of/irq: make of_msi_map_get_device_domain() bus agnostic dt-bindings: arm: fsl: Add msi-map device-tree binding for fsl-mc bus of/device: Add input id to of_dma_configure() of/iommu: Make of_map_rid() PCI agnostic ACPI/IORT: Add an input ID to acpi_dma_configure() ACPI/IORT: Remove useless PCI bus walk ACPI/IORT: Make iort_msi_map_rid() PCI agnostic ACPI/IORT: Make iort_get_device_domain IRQ domain agnostic ACPI/IORT: Make iort_match_node_callback walk the ACPI namespace for NC arm64: enable time namespace support arm64/vdso: Restrict splitting VVAR VMA arm64/vdso: Handle faults on timens page ...
2020-08-03Merge tag 'rm-unicore32' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/linuxLinus Torvalds40-40/+0
Pull unicore32 removal from Mike Rapoport: "Remove unicore32 support. The unicore32 port do not seem maintained for a long time now, there is no upstream toolchain that can create unicore32 binaries and all the links to prebuilt toolchains for unicore32 are dead. Even compilers that were available are not supported by the kernel anymore. Guenter Roeck says: "I have stopped building unicore32 images since v4.19 since there is no available compiler that is still supported by the kernel. I am surprised that support for it has not been removed from the kernel" However, it's worth pointing out two things: - Guan Xuetao is still listed as maintainer and asked for the port to be kept around the last time Arnd suggested removing it two years ago. He promised that there would be compiler sources (presumably llvm), but has not made those available since. - https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both released in 2016, with patches dated early 2019. These patches mainly restore a syscall ABI that was never part of mainline Linux but apparently used in production. qemu-2.8 removed support for that ABI and newer kernels (4.19+) can no longer be built with the old toolchain, so apparently there will not be any future updates to that git tree" * tag 'rm-unicore32' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/linux: MAINTAINERS: remove "PKUNITY SOC DRIVERS" entry rtc: remove fb-puv3 driver video: fbdev: remove fb-puv3 driver pwm: remove pwm-puv3 driver input: i8042: remove support for 8042-unicore32io i2c/buses: remove i2c-puv3 driver cpufreq: remove unicore32 driver arch: remove unicore32 port

2020-08-03udp_tunnel: add the ability to hard-code IANA VXLANJakub Kicinski1-0/+3
mlx5 has the IANA VXLAN port (4789) hard coded by the device, instead of being added dynamically when tunnels are created. To support this add a workaround flag to struct udp_tunnel_nic_info. Skipping updates for the port is fairly trivial, dumping the hard coded port via ethtool requires some code duplication. The port is not a part of any real table, we dump it in a special table which has no tunnel types supported and only one entry. This is the last known workaround / hack needed to convert all drivers to the new infra. Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2020-08-03Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscryptLinus Torvalds3-4/+35
Pull fscrypt updates from Eric Biggers: "This release, we add support for inline encryption via the blk-crypto framework which was added in 5.8. Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt', the contents of encrypted files will be encrypted/decrypted via blk-crypto, instead of directly using the crypto API. This model allows taking advantage of the inline encryption hardware that is integrated into the UFS or eMMC host controllers on most mobile SoCs. Note that this is just an alternate implementation; the ciphertext written to disk stays the same. (This pull request does *not* include support for direct I/O on encrypted files, which blk-crypto makes possible, since that part is still being discussed.) Besides the above feature update, there are also a few fixes and cleanups, e.g. strengthening some memory barriers that may be too weak. All these patches have been in linux-next with no reported issues. I've also tested them with the fscrypt xfstests, as usual. It's also been tested that the inline encryption support works with the support for Qualcomm and Mediatek inline encryption hardware that will be in the scsi pull request for 5.9. Also, several SoC vendors are already using a previous, functionally equivalent version of these patches" * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: fscrypt: don't load ->i_crypt_info before it's known to be valid fscrypt: document inline encryption support fscrypt: use smp_load_acquire() for ->i_crypt_info fscrypt: use smp_load_acquire() for ->s_master_keys fscrypt: use smp_load_acquire() for fscrypt_prepared_key fscrypt: switch fscrypt_do_sha256() to use the SHA-256 library fscrypt: restrict IV_INO_LBLK_* to AES-256-XTS fscrypt: rename FS_KEY_DERIVATION_NONCE_SIZE fscrypt: add comments that describe the HKDF info strings ext4: add inline encryption support f2fs: add inline encryption support fscrypt: add inline encryption support fs: introduce SB_INLINECRYPT

ASoC: Updates for v5.9 The biggest changes here one again come from Mormioto-san who has continued his dilligent work cleaning up long standing issues in the APIs, it's particularly nice to see the transition from digital_mute() to mute_stream() finally completed. There's also been a lot of work on the x86 code again, this time a big focus has been on cleaning up some issues identified by various static tests, and on the Freescale systems. Otherwise the biggest thing has been a lot of driver additions: - Convert users of digital_mute() to mute_stream(). - Simplify I/O helper functions. - Add a helper for getting the RTD from a substream. - Many, many fixes and cleanups to the x86 code. - New drivers for Freescale MQS and i.MX6sx, Intel KeemBay I2S, Maxim MAX98360A and MAX98373 Soundwire, several Mediatek boards, nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries boards (some of the first phones I worked on!) and TI J721e EVM.

2020-07-31dt-bindings: clock: Fix YAML schemas for LPASS clocks on SC7180Douglas Anderson1-4/+10
The YAML schemas that landed forgot one clock: "bi_tcxo". Presumably the bindings were developed against the v4 version of the driver and when the ".name" was removed in v5 of the driver things broke. While touching this, add the needed includes in each example. I believe both examples are supposed to be independent of each other. Let's fix the bindings.

2020-07-31powerpc/papr_scm: Fetch nvdimm performance stats from PHYPVaibhav Jain1-0/+27
Update papr_scm.c to query dimm performance statistics from PHYP via H_SCM_PERFORMANCE_STATS hcall and export them to user-space as PAPR specific NVDIMM attribute 'perf_stats' in sysfs. The patch also provide a sysfs ABI documentation for the stats being reported and their meanings. During NVDIMM probe time in papr_scm_nvdimm_init() a special variant of H_SCM_PERFORMANCE_STATS hcall is issued to check if collection of performance statistics is supported or not. If successful then a PHYP returns a maximum possible buffer length needed to read all performance stats. This returned value is stored in a per-nvdimm attribute 'stat_buffer_len'. The layout of request buffer for reading NVDIMM performance stats from PHYP is defined in 'struct papr_scm_perf_stats' and 'struct papr_scm_perf_stat'. These structs are used in newly introduced drc_pmem_query_stats() that issues the H_SCM_PERFORMANCE_STATS hcall. The sysfs access function perf_stats_show() uses value 'stat_buffer_len' to allocate a buffer large enough to hold all possible NVDIMM performance stats and passes it to drc_pmem_query_stats() to populate. Finally statistics reported in the buffer are formatted into the sysfs access function output buffer.

2020-07-31x86: Add support for ZSTD compressed kernelNick Terrell1-3/+3
- Add support for zstd compressed kernel - Define __DISABLE_EXPORTS in Makefile - Remove __DISABLE_EXPORTS definition from kaslr.c - Bump the heap size for zstd. - Update the documentation. Integrates the ZSTD decompression code to the x86 pre-boot code. Zstandard requires slightly more memory during the kernel decompression on x86 (192 KB vs 64 KB), and the memory usage is independent of the window size. __DISABLE_EXPORTS is now defined in the Makefile, which covers both the existing use in kaslr.c, and the use needed by the zstd decompressor in misc.c. This patch has been boot tested with both a zstd and gzip compressed kernel on i386 and x86_64 using buildroot and QEMU. Additionally, this has been tested in production on x86_64 devices. We saw a 2 second boot time reduction by switching kernel compression from xz to zstd.
