mm/memory_hotplug: introduce default dummy memory_add_physaddr_to_nid()
This is to introduce a general dummy helper. memory_add_physaddr_to_nid() is a fallback option to get the nid in case NUMA_NO_NID is detected. After this patch, arm64/sh/s390 can simply use the general dummy version. PowerPC/x86/ia64 will still use their specific version. This is the preparation to set a fallback value for dev_dax->target_node.

kasan, arm64: don't instrument functions that enable kasan
This patch prepares Software Tag-Based KASAN for stack tagging support. With stack tagging enabled, KASAN tags stack variable in each function in its prologue. In start_kernel() stack variables get tagged before KASAN is enabled via setup_arch()->kasan_init(). As the result the tags for start_kernel()'s stack variables end up in the temporary shadow memory. Later when KASAN gets enabled, switched to normal shadow, and starts checking tags, this leads to false-positive reports, as proper tags are missing in normal shadow. Disable KASAN instrumentation for start_kernel(). Also disable it for arm64's setup_arch() as a precaution (it doesn't have any stack variables right now).

mm/sparse: cleanup the code surrounding memory_present()
After removal of CONFIG_HAVE_MEMBLOCK_NODE_MAP we have two equivalent functions that call memory_present() for each region in memblock.memory: sparse_memory_present_with_active_regions() and membocks_present(). Moreover, all architectures have a call to either of these functions preceding the call to sparse_init() and in the most cases they are called one after the other. Mark the regions from memblock.memory as present during sparce_init() by making sparse_init() call memblocks_present(), make memblocks_present() and memory_present() functions static and remove redundant sparse_memory_present_with_active_regions() function. Also remove no longer required HAVE_MEMORY_PRESENT configuration option.

arm64/mm: enable vmem_altmap support for vmemmap mappings
Device memory ranges when getting hot added into ZONE_DEVICE, might require their vmemmap mapping's backing memory to be allocated from their own range instead of consuming system memory. This prevents large system memory usage for potentially large device memory ranges. Device driver communicates this request via vmem_altmap structure. Architecture needs to take this request into account while creating and tearing down vemmmap mappings. This enables vmem_altmap support in vmemmap_populate() and vmemmap_free() which includes vmemmap_populate_basepages() used for ARM64_16K_PAGES and ARM64_64K_PAGES configs.

mm/sparsemem: enable vmem_altmap support in vmemmap_alloc_block_buf()
There are many instances where vmemap allocation is often switched between regular memory and device memory just based on whether altmap is available or not. vmemmap_alloc_block_buf() is used in various platforms to allocate vmemmap mappings. Lets also enable it to handle altmap based device memory allocation along with existing regular memory allocations. This will help in avoiding the altmap based allocation switch in many places. To summarize there are two different methods to call vmemmap_alloc_block_buf(). vmemmap_alloc_block_buf(size, node, NULL) /* Allocate from system RAM */ vmemmap_alloc_block_buf(size, node, altmap) /* Allocate from altmap */ This converts altmap_alloc_block_buf() into a static function, drops it's entry from the header and updates Documentation/vm/memory-model.rst.

mm/sparsemem: enable vmem_altmap support in vmemmap_populate_basepages()
Patch series "arm64: Enable vmemmap mapping from device memory", v4. This series enables vmemmap backing memory allocation from device memory ranges on arm64. But before that, it enables vmemmap_populate_basepages() and vmemmap_alloc_block_buf() to accommodate struct vmem_altmap based alocation requests. This patch (of 3): vmemmap_populate_basepages() is used across platforms to allocate backing memory for vmemmap mapping. This is used as a standard default choice or as a fallback when intended huge pages allocation fails. This just creates entire vmemmap mapping with base pages (PAGE_SIZE). On arm64 platforms, vmemmap_populate_basepages() is called instead of the platform specific vmemmap_populate() when ARM64_SWAPPER_USES_SECTION_MAPS is not enabled as in case for ARM64_16K_PAGES and ARM64_64K_PAGES configs. At present vmemmap_populate_basepages() does not support allocating from driver defined struct vmem_altmap while trying to create vmemmap mapping for a device memory range. It prevents ARM64_16K_PAGES and ARM64_64K_PAGES configs on arm64 from supporting device memory with vmemap_altmap request. This enables vmem_altmap support in vmemmap_populate_basepages() unlocking device memory allocation for vmemap mapping on arm64 platforms with 16K or 64K base page configs. Each architecture should evaluate and decide on subscribing device memory based base page allocation through vmemmap_populate_basepages(). Hence lets keep it disabled on all archs in order to preserve the existing semantics. A subsequent patch enables it on arm64.

asm-generic: pgalloc: provide generic pmd_alloc_one() and pmd_free_one()
For most architectures that support >2 levels of page tables, pmd_alloc_one() is a wrapper for __get_free_pages(), sometimes with __GFP_ZERO and sometimes followed by memset(0) instead. More elaborate versions on arm64 and x86 account memory for the user page tables and call to pgtable_pmd_page_ctor() as the part of PMD page initialization. Move the arm64 version to include/asm-generic/pgalloc.h and use the generic version on several architectures. The pgtable_pmd_page_ctor() is a NOP when ARCH_ENABLE_SPLIT_PMD_PTLOCK is not enabled, so there is no functional change for most architectures except of the addition of __GFP_ACCOUNT for allocation of user page tables. The pmd_free() is a wrapper for free_page() in all the cases, so no functional change here.

mm: remove unneeded includes of <asm/pgalloc.h>
Patch series "mm: cleanup usage of <asm/pgalloc.h>" Most architectures have very similar versions of pXd_alloc_one() and pXd_free_one() for intermediate levels of page table. These patches add generic versions of these functions in <asm-generic/pgalloc.h> and enable use of the generic functions where appropriate. In addition, functions declared and defined in <asm/pgalloc.h> headers are used mostly by core mm and early mm initialization in arch and there is no actual reason to have the <asm/pgalloc.h> included all over the place. The first patch in this series removes unneeded includes of <asm/pgalloc.h> In the end it didn't work out as neatly as I hoped and moving pXd_alloc_track() definitions to <asm-generic/pgalloc.h> would require unnecessary changes to arches that have custom page table allocations, so I've decided to move lib/ioremap.c to mm/ and make pgalloc-track.h local to mm/. This patch (of 8): In most cases <asm/pgalloc.h> header is required only for allocations of page table memory. Most of the .c files that include that header do not use symbols declared in <asm/pgalloc.h> and do not require that header. As for the other header files that used to include <asm/pgalloc.h>, it is possible to move that include into the .c file that actually uses symbols from <asm/pgalloc.h> and drop the include from the header file. The process was somewhat automated using sed -i -E '/[<"]asm\/pgalloc\.h/d' \ $(grep -L -w -f /tmp/xx \ $(git grep -E -l '[<"]asm/pgalloc\.h')) where /tmp/xx contains all the symbols defined in arch/*/include/asm/pgalloc.h.

It allows to efficiently close a range of file descriptors up to all file descriptors of a calling task. This is coordinated with the FreeBSD folks which have copied our version of this syscall and in the meantime have already merged it in April 2019: https://reviews.freebsd.org/D21627 https://svnweb.freebsd.org/base?view=revision&revision=359836 The syscall originally came up in a discussion around the new mount API and making new file descriptor types cloexec by default. During this discussion, Al suggested the close_range() syscall. First, it helps to close all file descriptors of an exec()ing task. This can be done safely via (quoting Al's example from [1] verbatim): /* that exec is sensitive */ unshare(CLONE_FILES); /* we don't want anything past stderr here */ close_range(3, ~0U); execve(....); The code snippet above is one way of working around the problem that file descriptors are not cloexec by default. This is aggravated by the fact that we can't just switch them over without massively regressing userspace. For a whole class of programs having an in-kernel method of closing all file descriptors is very helpful (e.g. demons, service managers, programming language standard libraries, container managers etc.). Second, it allows userspace to avoid implementing closing all file descriptors by parsing through /proc/<pid>/fd/* and calling close() on each file descriptor and other hacks. From looking at various large(ish) userspace code bases this or similar patterns are very common in service managers, container runtimes, and programming language runtimes/standard libraries such as Python or Rust. In addition, the syscall will also work for tasks that do not have procfs mounted and on kernels that do not have procfs support compiled in. In such situations the only way to make sure that all file descriptors are closed is to call close() on each file descriptor up to UINT_MAX or RLIMIT_NOFILE, OPEN_MAX trickery. Based on Linus' suggestion close_range() also comes with a new flag CLOSE_RANGE_UNSHARE to more elegantly handle file descriptor dropping right before exec. This would usually be expressed in the sequence: unshare(CLONE_FILES); close_range(3, ~0U); as pointed out by Linus it might be desirable to have this be a part of close_range() itself under a new flag CLOSE_RANGE_UNSHARE which gets especially handy when we're closing all file descriptors above a certain threshold.

High-level this does two main things: - Remove the double export of both do_fork() and _do_fork() where do_fork() used the incosistent legacy clone calling convention. Now we only export _do_fork() which is based on struct kernel_clone_args. - Remove the copy_thread_tls()/copy_thread() split making the architecture specific HAVE_COYP_THREAD_TLS config option obsolete. This switches all remaining architectures to select HAVE_COPY_THREAD_TLS and thus to the copy_thread_tls() calling convention. The current split makes the process creation codepaths more convoluted than they need to be. Each architecture has their own copy_thread() function unless it selects HAVE_COPY_THREAD_TLS then it has a copy_thread_tls() function. The split is not needed anymore nowadays, all architectures support CLONE_SETTLS but quite a few of them never bothered to select HAVE_COPY_THREAD_TLS and instead simply continued to use copy_thread() and use the old calling convention. Removing this split cleans up the process creation codepaths and paves the way for implementing clone3() on such architectures since it requires the copy_thread_tls() calling convention. After having made each architectures support copy_thread_tls() this series simply renames that function back to copy_thread(). It also switches all architectures that call do_fork() directly over to _do_fork() and the struct kernel_clone_args calling convention. This is a corollary of switching the architectures that did not yet support it over to copy_thread_tls() since do_fork() is conditional on not supporting copy_thread_tls() (Mostly because it lacks a separate argument for tls which is trivial to fix but there's no need for this function to exist.). The do_fork() removal is in itself already useful as it allows to to remove the export of both do_fork() and _do_fork() we currently have in favor of only _do_fork(). This has already been discussed back when we added clone3(). The legacy clone() calling convention is - as is probably well-known - somewhat odd: # # ABI hall of shame # config CLONE_BACKWARDS config CLONE_BACKWARDS2 config CLONE_BACKWARDS3 that is aggravated by the fact that some architectures such as sparc follow the CLONE_BACKWARDSx calling convention but don't really select the corresponding config option since they call do_fork() directly. So do_fork() enforces a somewhat arbitrary calling convention in the first place that doesn't really help the individual architectures that deviate from it. They can thus simply be switched to _do_fork() enforcing a single calling convention. (I really hope that any new architectures will __not__ try to implement their own calling conventions...) Most architectures already have made a similar switch (m68k comes to mind). Overall this removes more code than it adds even with a good portion of added comments. It simplifies a chunk of arch specific assembly either by moving the code into C or by simply rewriting the assembly. Architectures that have been touched in non-trivial ways have all been actually boot and stress tested: sparc and ia64 have been tested with Debian 9 images. They are the two architectures which have been touched the most. All non-trivial changes to architectures have seen acks from the relevant maintainers. nios2 with a custom built buildroot image. h8300 I couldn't get something bootable to test on but the changes have been fairly automatic and I'm sure we'll hear people yell if I broke something there. All other architectures that have been touched in trivial ways have been compile tested for each single patch of the series via git rebase -x "make ..." v5.8-rc2. arm{64} and x86{_64} have been boot tested even though they have just been trivially touched (removal of the HAVE_COPY_THREAD_TLS macro from their Kconfig) because well they are basically "core architectures" and since it is trivial to get your hands on a useable image" * tag 'fork-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: arch: rename copy_thread_tls() back to copy_thread() arch: remove HAVE_COPY_THREAD_TLS unicore: switch to copy_thread_tls() sh: switch to copy_thread_tls() nds32: switch to copy_thread_tls() microblaze: switch to copy_thread_tls() hexagon: switch to copy_thread_tls() c6x: switch to copy_thread_tls() alpha: switch to copy_thread_tls() fork: remove do_fork() h8300: select HAVE_COPY_THREAD_TLS, switch to kernel_clone_args nios2: enable HAVE_COPY_THREAD_TLS, switch to kernel_clone_args ia64: enable HAVE_COPY_THREAD_TLS, switch to kernel_clone_args sparc: unconditionally enable HAVE_COPY_THREAD_TLS sparc: share process creation helpers between sparc and sparc64 sparc64: enable HAVE_COPY_THREAD_TLS fork: fold legacy_clone_args_valid() into _do_fork() |

ARM: new SoC support for v5.9
There are three SoC families newly dded to the 32-bit and 64-bit Arm architecture code in the kernel this time: - Daniel Palmer adds initial support for two chips made by MStar, a taiwanese SoC manufacturer that became part of Mediatek in 2012. For now, the added support is fairly minimal, with just two of its Cortex-A7 based 32-bit camera chips getting support for a limited set of on-chip peripherals. - Lars Povlsen from Microchip adds support for their new Sparx5 family of ethernet switch chips using 64-bit Cortex-A53 cores. These are descended from earlier VSC7xxx SparX and Ocelot chips using 32-bit MIPS cores. - Daniele Alessandrelli from Intel adds support for the new Keem Bay SoC for computer vision, built around a Movidius VPU with Linux running on Arm Cortex-A53 cores.

There are also a number of updates to SoC specific drivers, the main ones are: - Mediatek cmdq driver gains a few in-kernel interfaces - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding support for additional SoC variants - The Qualcomm GENI core code gains interconnect path voting and performance level support, and integrating this into a number of device drivers. - A new driver for Samsung Exynos5800 voltage coupler for - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC specific device drivers - Updates to the TI K3 Ring Accelerator driver" * tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (164 commits) soc: qcom: geni: Fix unused label warning soc: qcom: smd-rpm: Fix kerneldoc memory: jz4780_nemc: Only request IO memory the driver will use soc: qcom: pdr: Reorder the PD state indication ack MAINTAINERS: Add Git repository for memory controller drivers memory: brcmstb_dpfe: Fix language typo memory: samsung: exynos5422-dmc: Correct white space issues memory: samsung: exynos-srom: Correct alignment memory: pl172: Enclose macro argument usage in parenthesis memory: of: Correct kerneldoc memory: omap-gpmc: Fix language typo memory: omap-gpmc: Correct white space issues memory: omap-gpmc: Use 'unsigned int' for consistency memory: omap-gpmc: Enclose macro argument usage in parenthesis memory: omap-gpmc: Correct kerneldoc memory: mvebu-devbus: Align with open parenthesis memory: mvebu-devbus: Add missing braces to all arms of if statement memory: bt1-l2-ctl: Add blank lines after declarations soc: TI knav_qmss: make symbol 'knav_acc_range_ops' static firmware: ti_sci: Replace HTTP links with HTTPS ones ... |

ARM: SoC DT changes for 5.9
As usual, there are many patches addressing minor issues in existing DTS files, such as DTC warnings, or adding support for additional peripherals. There are three added SoCs in existing product families: - Amazon: Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs, otherwise known as AL73400 or first-generation Graviton, and following the already supported Cortex-A1`5 and Cortex-A57 based Alpine chips. This one is added together with the official Evaluation platform. - Qualcomm: The Snapdragon SDM630 platform is a family of mid-range mobile phone chips from 2017 based on Cortex-A53 or Kryo 260 CPUs. A total of five end-user products are added based on these, all Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and XA2 Ultra. - Renesas: RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G family, and apparently closely related to the RZ/G2N and RZ/G2M models we already support but has a faster GPU and additional on-chip peripherals. It is added along with the HopeRun HiHope RZ/G2H development board A small number of new boards for already supported SoCs also debut: - Allwinner sunxi: Only one new machine, revision v1.2 of the Pine64 PinePhone (non-Android) smartphone, containing minor changes compared to earlier versions. - Amlogic Meson: WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box - Aspeed: EthanolX is AMD's EPYC data center rerence platform, using an ASpeed AST2600 baseboard management controller. - Mediatek: Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook based on the MT8183 (Helio P60t) SoC. - Nvidia Tegra: ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android tablets from around 2012 using Tegra 3 and Tegra 2, respectively. Thanks to PostmarketOS, these can now run mainline kernels and become useful again. The Jetson Xavier NX Developer Kit uses a SoM and carrier board for the Tegra194, their latest 64-bit chip based on Carmel CPU cores and Volta graphics. - NXP i.MX: Five new boards based on the 32-bit i.MX6 series are added: The MYiR MYS-6ULX single-board computer, and four different models of industrial computers from Protonic. - Qualcomm: MikroTik RouterBoard 3011 is a rackmounted router based on the 32-bit IPQ8064 networking SoC Three older phones get added, the Snapdragon 808 (msm8992) based Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running Windows Phone, and the Snapdragon 810 (msm8994) based Sony Xperia Z5. - Renesas: In addition to the HiHope RZ/G2H board mentioned above, we gain support for board versions 3.0 and 4.0 of the earlier RZ/G2M and RZ/G2N reference boards. Beacon EmbeddedWorks adds another SoM+Carrier development board for RZ/G2M. - Rockchips: Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it is based on, using the high-end 32-bit rk3288 SoC. Notable updates to existing platforms are usually for added on-chip peripherals, including: - ASpeed AST2xxx (various) - Allwinner (cpufreq, thermal, Pinephone touchscreen) - Amlogic Meson (audio, gpu dvdfs, board updates) - Arm Versatile - Broadcom (board updates for switch ports, Raspberry pi clock updates) - Hisilicon (various) - Intel/Altera SoCFPGA (various) - Marvell Armada 7xxx/8xxx (smmu) - Marvell MMP (GPU on mmp2/mmp3) - Mediatek mt8183 (USB, pericfg) - NXP Layerscape (VPU, thermal, DSPI) - NXP i.MX (VPU, bindings, board updates) - Nvidia Tegra194 (GPU) - Qualcomm (GPU, Interconnect, ...) - Renesas R-Car (SPI, IPMMU, board updates) - STMicroelectronics STM32 (various) - Samsung Exynos (various) - Socionext Uniphier (updates to serial, and pcie) - TI K3 (serdes, usb3, audio, sd, chipid) - TI OMAP (IPU/DSP remoteproc changes, dropping platform data) Signed-off-by: Arnd Bergmann <arnd@arndb.de> -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEo6/YBQwIrVS28WGKmmx57+YAGNkFAl8j3zoACgkQmmx57+YA GNlOAQ//RuU0v5AyUyZZGsYKcKltg0qCiUj+CWldlaHS41oJQ9UC4e2kqhZtR28V Cqe853h976Xm74Fr7Hci4OCo9wxGrNLXFgNkNrYzR9ud76eEcSTQX8Jj9slZvLVu fEzNOK4VD0cIDRkw5xNZfGHGUSN7ttOV+NClVSA2zBiKv8jNivRI24+vvc+f92yb d5P7+aeex19xSOiMmuuj5yBbU+85pbR5aoRRS5Ohe5mVL5wW9LQTs7Otsk989FBe jOCthKfPFtxTTYMrWmM3P0DcHku/MNAsRQKUysrJlMcSefXOgkfMuN6cw4xypXAS OvFNnIp8cigt8MLWIyU2AiLkkr3FpEsZQliy4XTBl1n6mGlRHB5wD8i294cLtQlJ EO5yu3I3UimIyG7i4aWCy0sJMYedDrnoYisQk00aDbzea7quSuXC9yo9IompdBsr Fqn5D7tFnVs79v/2zDhqlMU8GmFSoqPyfPSE3dgLCOHlMdd2ToD9I4ahtsJVZTjk 1Ro9TMFK+b5LIQot1inOPff0aurpZPLA7wmxUfez51IwG4UdVsmtawwPCl6OrgYm TttK+J1yuCMSxds7QC3rPfiubc+RLEy+IQxP1tR55THg72RDWRnwXTXb5AvAu/vx GbY1AzGszdr1+mR04CKbFyICG0l0vlyuX9qSsknRW48MaYgn8GQ= =Tpj3 -----END PGP SIGNATURE----- Merge tag 'arm-dt-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC DT updates from Arnd Bergmann: "As usual, there are many patches addressing minor issues in existing DTS files, such as DTC warnings, or adding support for additional peripherals.

(The default is to maximize performance & reduce RT latencies.) - Improve utime and stime tracking accuracy, which had a fixed boundary of error, which created larger and larger relative errors as the values become larger. This is now replaced with more precise arithmetics, using the new mul_u64_u64_div_u64() helper in math64.h. - Improve the deadline scheduler, such as making it capacity aware - Improve frequency-invariant scheduling - Misc cleanups in energy/power aware scheduling - Add sched_update_nr_running tracepoint to track changes to nr_running - Documentation additions and updates - Misc cleanups and smaller fixes Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAl8oJDURHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1ixLg//bqWzFlfWirvngTgDxDnplwUTyKXmMCcq R1IYhlyK2O5FxvhbRmdmW11W3yzyTPvgCs6Q/70negGaPNe2w1OxfxiK9NMKz5eu M1LoXas7pL5g7Pr/ZxxHk/8VqJLV4t9MkodiiInmV6lTaznT3sU6a/kpYQjJyFnG Tuu9jd6JhdRKmePDJnNmUBoGQ7JiOQDcX4HtkcQ3OA+An3624tmJzbW1yts+uj7J ZWo2EY60RfbA9MxQXGPOaR/nAjngWs4Q6tddAh10mftsPq1gR2iFUKju1d31MQt/ RHLdiqJf+AyUC4popKG7a+7ilCKMBwPociSreTJNPyEUQ1X4AM3vUVk4yjUoiDph k2WdsCF8/JRdhXg0NnrpPUqOaAbQj53EeXnitEb92E7WyTZgLOvAtpV//xZo6utp 2QHerfrQ9SoGQjz/ho78za5vQtV1x25yDhd+X4XV4QEhIy85G9/2JCpC/Kc/TXLf OO7A4X69XztKTEJhP60g8ldCPUe4N2vbh1vKY6oAD8AFQVVNZ6n7375/Qa//b0/k ++hcYkPc2EK97/aBFdvzDgqb7aUo7Mtn2ibke16sQU4szulaoRuAHQG4jdGKMwbD dk2VBoxyxeYFXWHsNneSe87+ha3sd0dSN0ul1EB/SlFrVELMvy634YXnMYGW8ima PzyPB0ezpuA= =PbO7 -----END PGP SIGNATURE----- Merge tag 'sched-core-2020-08-03' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Ingo Molnar: - Improve uclamp performance by using a static key for the fast path - Add the "sched_util_clamp_min_rt_default" sysctl, to optimize for better power efficiency of RT tasks on battery powered devices.

arm64 and cross-arch updates for 5.9:
- 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. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE5RElWfyWxS+3PLO2a9axLQDIXvEFAl8oTcsACgkQa9axLQDI XvEj6hAAkn39mO5xrR/Vhpg3DyFPk63ZlMSX9SsOeVyaLbovT6stTs1XAZXPpnkt rV3gwACyGSrqH6+uey9pHgHJuPF2TdrGEVK08yVKo9KGW/6yXSIncdKFE4jUJ/WJ wF5j7eMET2aGzcpm5AlzMmq6HOrKB8nZac9H8/x6H+Ox2WdgJkEjOkDvyqACUyum N3FsTZkWj2pIkTXHNgDZ8KjxVLO8HlFaB2hkxFDl9NPlX2UTCQJ8Tg1KiPLafKaK gUvH4usQDFdb5RU/UWogre37J4emO0ZTApZOyju+U+PMMWlWVHjZ4isUIS9zz/AE JNZ23dnKZX2HrYa5p8HZx175zwj/vXUqUHCZPLvQXaAudCEhF8BVljPiG0e80FV5 GHFUgUbylKspp01I/9L+2JvsG96Mr0e+P3Sx7L2HTI42cmtoSa14+MpoSRj7zlft Qcl8hfrVOjCjUnFRHa/1y1cGvnD9GbgnKJR7zgVxl9bD/Jd48r1HUtwRORZCzWFr mRPVbPS72fWxMzMV9DZYJm02jJY9kLX2BMl49njbB8MhAhzOvrMVzoVVtMMeRFLR XHeJpmg36W09FiRGe7LRXlkXIhCQzQG2bJfiphuupCfhjRAitPoq8I925G6Pig60 c8RWaXGU7PrEsdMNrL83vekvGKgqrkoFkRVtsCoQ2X6Hvu/XdYI= =mh79 -----END PGP SIGNATURE----- Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 and cross-arch updates from Catalin Marinas: "Here's a slightly wider-spread set of updates for 5.9.

bpf, arm64: Add BPF exception tables
When a tracing BPF program attempts to read memory without using the bpf_probe_read() helper, the verifier marks the load instruction with the BPF_PROBE_MEM flag. Since the arm64 JIT does not currently recognize this flag it falls back to the interpreter. Add support for BPF_PROBE_MEM, by appending an exception table to the BPF program. If the load instruction causes a data abort, the fixup infrastructure finds the exception table and fixes up the fault, by clearing the destination register and jumping over the faulting instruction. To keep the compact exception table entry format, inspect the pc in fixup_exception(). A more generic solution would add a "handler" field to the table entry, like on x86 and s390.

arm64: csum: Fix handling of bad packets
Although iph is expected to point to at least 20 bytes of valid memory,
ihl may be bogus, for example on reception of a corrupt packet. If it
happens to be less than 5, we really don't want to run away and
dereference 16GB worth of memory until it wraps back to exactly zero...

arm64/mm: save memory access in check_and_switch_context() fast switch path
On arm64, smp_processor_id() reads a per-cpu `cpu_number` variable, using the per-cpu offset stored in the tpidr_el1 system register. In some cases we generate a per-cpu address with a sequence like: cpu_ptr = &per_cpu(ptr, smp_processor_id()); Which potentially incurs a cache miss for both `cpu_number` and the in-memory `__per_cpu_offset` array. This can be written more optimally as: cpu_ptr = this_cpu_ptr(ptr); Which only needs the offset from tpidr_el1, and does not need to load from memory. The following two test cases show a small performance improvement measured on a 46-cpus qualcomm machine with 5.8.0-rc4 kernel. Test 1: (about 0.3% improvement) #cat b.sh make clean && make all -j138 #perf stat --repeat 10 --null --sync sh b.sh - before this patch Performance counter stats for 'sh b.sh' (10 runs): 298.62 +- 1.86 seconds time elapsed ( +- 0.62% ) - after this patch Performance counter stats for 'sh b.sh' (10 runs): 297.734 +- 0.954 seconds time elapsed ( +- 0.32% ) Test 2: (about 1.69% improvement) 'perf stat -r 10 perf bench sched messaging' Then sum the total time of 'sched/messaging' by manual. - before this patch total 0.707 sec for 10 times - after this patch totol 0.695 sec for 10 times Signed-off-by: Pingfan Liu <kernelfans@gmail.com> Acked-by: Mark Rutland <mark.rutland@arm.com> Cc: Will Deacon <will@kernel.org> Cc: Steve Capper <steve.capper@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Vladimir Murzin <vladimir.murzin@arm.com> Cc: Jean-Philippe Brucker <jean-philippe@linaro.org> Link: https://lore.kernel.org/r/1594389852-19949-1-git-send-email-kernelfans@gmail.com Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> |
