git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull kernel_clone() updates from Christian Brauner: "During the v5.9 merge window we reworked the process creation codepaths across multiple architectures. After this work we were only left with the _do_fork() helper based on the struct kernel_clone_args calling convention. As was pointed out _do_fork() isn't valid kernelese especially for a helper that isn't just static. This series removes the _do_fork() helper and introduces the new kernel_clone() helper. The process creation cleanup didn't change the name to something more reasonable mainly because _do_fork() was used in quite a few places. So sending this as a separate series seemed the better strategy. I originally intended to send this early in the v5.9 development cycle after the merge window had closed but given that this was touching quite a few places I decided to defer this until the v5.10 merge window" * tag 'kernel-clone-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: sched: remove _do_fork() tracing: switch to kernel_clone() kgdbts: switch to kernel_clone() kprobes: switch to kernel_clone() x86: switch to kernel_clone() sparc: switch to kernel_clone() nios2: switch to kernel_clone() m68k: switch to kernel_clone() ia64: switch to kernel_clone() h8300: switch to kernel_clone() fork: introduce kernel_clone()

2020-10-13mm: memcontrol: add the missing numa_stat interface for cgroup v2Muchun Song1-20/+49
In the cgroup v1, we have a numa_stat interface. This is useful for providing visibility into the numa locality information within an memcg since the pages are allowed to be allocated from any physical node. One of the use cases is evaluating application performance by combining this information with the application's CPU allocation. But the cgroup v2 does not. So this patch adds the missing information.

2020-10-13kbuild: doc: describe proper script invocationLukas Bulwahn1-0/+20
During an investigation to fix up the execute bits of scripts in the kernel repository, Andrew Morton and Kees Cook pointed out that the execute bit should not matter, and that build scripts cannot rely on that. Kees could not point to any documentation, though. Masahiro Yamada explained the convention of setting execute bits to make it easier for manual script invocation. Provide some basic documentation how the build shall invoke scripts, such that the execute bits do not matter, and acknowledge that execute bits are useful nonetheless. This serves as reference for further clean-up patches in the future.

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux Pull printk updates from Petr Mladek: "The big new thing is the fully lockless ringbuffer implementation, including the support for continuous lines. It will allow to store and read messages in any situation wihtout the risk of deadlocks and without the need of temporary per-CPU buffers. The access is still serialized by logbuf_lock. It synchronizes few more operations, for example, temporary buffer for formatting the message, syslog and kmsg_dump operations. The lock removal is being discussed and should be ready for the next release. The continuous lines are handled exactly the same way as before to avoid regressions in user space. It means that they are appended to the last message when the caller is the same. Only the last message can be extended. The data ring includes plain text of the messages. Except for an integer at the beginning of each message that points back to the descriptor ring with other metadata. The dictionary has to stay. journalctl uses it to filter the log. It allows to show messages related to a given device. The dictionary values are stored in the descriptor ring with the other metadata. This is the first part of the printk rework as discussed at Plumbers 2019, see https://lore.kernel.org/r/87k1acz5rx.fsf@linutronix.de. The next big step will be handling consoles by kthreads during the normal system operation. It will require special handling of situations when the kthreads could not get scheduled, for example, early boot, suspend, panic. Other changes: - Add John Ogness as a reviewer for printk subsystem. He is author of the rework and is familiar with the code and history. - Fix locking in serial8250_do_startup() to prevent lockdep report. - Few code cleanups" * tag 'printk-for-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: (27 commits) printk: Use fallthrough pseudo-keyword printk: reduce setup_text_buf size to LOG_LINE_MAX printk: avoid and/or handle record truncation printk: remove dict ring printk: move dictionary keys to dev_printk_info printk: move printk_info into separate array printk: reimplement log_cont using record extension printk: ringbuffer: add finalization/extension support printk: ringbuffer: change representation of states printk: ringbuffer: clear initial reserved fields printk: ringbuffer: add BLK_DATALESS() macro printk: ringbuffer: relocate get_data() printk: ringbuffer: avoid memcpy() on state_var printk: ringbuffer: fix setting state in desc_read() kernel.h: Move oops_in_progress to printk.h scripts/gdb: update for lockless printk ringbuffer scripts/gdb: add utils.read_ulong() docs: vmcoreinfo: add lockless printk ringbuffer vmcoreinfo printk: reduce LOG_BUF_SHIFT range for H8300 printk: ringbuffer: support dataless records ...

2020-10-13dt: Remove booting-without-of.rstRob Herring10-1586/+175
booting-without-of.rst is an ancient document that first outlined Flattened DeviceTree on PowerPC initially. The DT world has evolved a lot in the 15 years since and booting-without-of.rst is pretty stale. The name of the document itself is confusing if you don't understand the evolution from real 'OpenFirmware'. Most of what booting-without-of.rst contains is now in the DT specification (which evolved out of the ePAPR). The few things that weren't documented in the DT specification are now. All that remains is the boot entry details, so let's move these to arch specific documents. The exception is arm which already has the same details documented.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This time very little driver changes but lots of core changes. We have some interesting cooperative work for ARM and Intel alike, making the GPIO subsystem more and more suitable for industrial systems and the like, in addition to the in-kernel users. We touch driver core (device properties) and lib/* by adding one simple string array free function, these are authored by Andy Shevchenko who is a well known and recognized core helpers maintainers so this should be fine. We also see some Android GKI-related modularization in the MXC drivers. Core changes: - The big core change is the updated (v2) userspace character device API. This corrects badly designed 64-bit alignment around the line events. We also add the debounce request feature. This echoes the often quotes passage from Frederick Brooks "The mythical man-month" to always throw one away, which we have seen before in things such as V4L2. So we put in a new one and deprecate and obsolete the old one. - All example tools in tools/gpio/* are migrated to the new API to set a good example. The libgpiod userspace library has been augmented to use this new API pretty much from day 1. - Some misc API hardening by using strn* function calls has been added as well. - Use the simpler IDA interface for GPIO chip instance enumeration. - Add device core function for counting string arrays in device properties. - Provide a generic library function kfree_strarray() that can be used throughout the kernel. Driver enhancements: - The DesignWare dwapb-gpio driver has been enhanced and now uses the IRQ handling in the gpiolib core. - The mockup and aggregator drivers have seen some substantial code clean-up and now use more of the core kernel inftrastructure. - Misc cleanups using dev_err_probe(). - The MXC drivers (Freescale/NXP) can now be built modularized, which makes modularized GKI Android kernels happy" * tag 'gpio-v5.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (73 commits) gpiolib: Update header block in gpiolib-cdev.h gpiolib: cdev: switch from kstrdup() to kstrndup() docs: gpio: add a new document to its index.rst gpio: pca953x: Add support for the NXP PCAL9554B/C tools: gpio: add debounce support to gpio-event-mon tools: gpio: add multi-line monitoring to gpio-event-mon tools: gpio: port gpio-event-mon to v2 uAPI tools: gpio: port gpio-hammer to v2 uAPI tools: gpio: rename nlines to num_lines tools: gpio: port gpio-watch to v2 uAPI tools: gpio: port lsgpio to v2 uAPI gpio: uapi: document uAPI v1 as deprecated gpiolib: cdev: support setting debounce gpiolib: cdev: support GPIO_V2_LINE_SET_VALUES_IOCTL gpiolib: cdev: support GPIO_V2_LINE_SET_CONFIG_IOCTL gpiolib: cdev: support edge detection for uAPI v2 gpiolib: cdev: support GPIO_V2_GET_LINEINFO_IOCTL and GPIO_V2_GET_LINEINFO_WATCH_IOCTL gpiolib: cdev: support GPIO_V2_GET_LINE_IOCTL and GPIO_V2_LINE_GET_VALUES_IOCTL gpiolib: add build option for CDEV v1 ABI gpiolib: make cdev a build option ...

This allows printk() to store multiple timestamps in the ringbuffer which is useful for coordinating dmesg information across a fleet of machines. - Provide a multi-timestamp accessor for printk() - Make timer init more robust by checking for invalid timer flags. - Comma vs semicolon fixes Drivers: - Support for new platforms in existing drivers (SP804 and Renesas CMT) - Comma vs semicolon fixes * tag 'timers-core-2020-10-12' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: clocksource/drivers/armada-370-xp: Use semicolons rather than commas to separate statements clocksource/drivers/mps2-timer: Use semicolons rather than commas to separate statements timers: Mask invalid flags in do_init_timer() clocksource/drivers/sp804: Enable Hisilicon sp804 timer 64bit mode clocksource/drivers/sp804: Add support for Hisilicon sp804 timer clocksource/drivers/sp804: Support non-standard register offset clocksource/drivers/sp804: Prepare for support non-standard register offset clocksource/drivers/sp804: Remove a mismatched comment clocksource/drivers/sp804: Delete the leading "__" of some functions clocksource/drivers/sp804: Remove unused sp804_timer_disable() and timer-sp804.h clocksource/drivers/sp804: Cleanup clk_get_sys() dt-bindings: timer: renesas,cmt: Document r8a774e1 CMT support dt-bindings: timer: renesas,cmt: Document r8a7742 CMT support alarmtimer: Convert comma to semicolon timekeeping: Provide multi-timestamp accessor to NMI safe timekeeper timekeeping: Utilize local_clock() for NMI safe timekeeper during early boot
