      Pull tracing updates from Steven Rostedt:
       "New tracing features:
      
         - New PERMANENT flag to ftrace_ops when attaching a callback to a
           function.
      
           As /proc/sys/kernel/ftrace_enabled when set to zero will disable
           all attached callbacks in ftrace, this has a detrimental impact on
           live kernel tracing, as it disables all that it patched. If a
           ftrace_ops is registered to ftrace with the PERMANENT flag set, it
           will prevent ftrace_enabled from being disabled, and if
           ftrace_enabled is already disabled, it will prevent a ftrace_ops
           with PREMANENT flag set from being registered.
      
         - New register_ftrace_direct().
      
           As eBPF would like to register its own trampolines to be called by
           the ftrace nop locations directly, without going through the ftrace
           trampoline, this function has been added. This allows for eBPF
           trampolines to live along side of ftrace, perf, kprobe and live
           patching. It also utilizes the ftrace enabled_functions file that
           keeps track of functions that have been modified in the kernel, to
           allow for security auditing.
      
         - Allow for kernel internal use of ftrace instances.
      
           Subsystems in the kernel can now create and destroy their own
           tracing instances which allows them to have their own tracing
           buffer, and be able to record events without worrying about other
           users from writing over their data.
      
         - New seq_buf_hex_dump() that lets users use the hex_dump() in their
           seq_buf usage.
      
         - Notifications now added to tracing_max_latency to allow user space
           to know when a new max latency is hit by one of the latency
           tracers.
      
         - Wider spread use of generic compare operations for use of bsearch
           and friends.
      
         - More synthetic event fields may be defined (32 up from 16)
      
         - Use of xarray for architectures with sparse system calls, for the
           system call trace events.
      
        This along with small clean ups and fixes"

      Linus Torvalds authored
      Pull powerpc Spectre-RSB fixes from Michael Ellerman:
       "We failed to activate the mitigation for Spectre-RSB (Return Stack
        Buffer, aka. ret2spec) on context switch, on CPUs prior to Power9
        DD2.3.
      
        That allows a process to poison the RSB (called Link Stack on Power
        CPUs) and possibly misdirect speculative execution of another process.
        If the victim process can be induced to execute a leak gadget then it
        may be possible to extract information from the victim via a side
        channel.
      
        The fix is to correctly activate the link stack flush mitigation on
        all CPUs that have any mitigation of Spectre v2 in userspace enabled.
      
        There's a second commit which adds a link stack flush in the KVM guest
        exit path. A leak via that path has not been demonstrated, but we
        believe it's at least theoretically possible.
      
        This is the fix for CVE-2019-18660"

      Linus Torvalds authored
      Pull driver core updates from Greg KH:
       "Here is the "big" set of driver core patches for 5.5-rc1
      
        There's a few minor cleanups and fixes in here, but the majority of
        the patches in here fall into two buckets:
      
         - debugfs api cleanups and fixes
      
         - driver core device link support for boot dependancy issues
      
        The debugfs api cleanups are working to slowly refactor the debugfs
        apis so that it is even harder to use incorrectly. That work has been
        happening for the past few kernel releases and will continue over
        time, it's a long-term project/goal
      
        The driver core device link support missed 5.4 by just a bit, so it's
        been sitting and baking for many months now. It's from Saravana Kannan
        to help resolve the problems that DT-based systems have at boot time
        with dependancy graphs and kernel modules. Turns out that no one has
        actually tried to build a generic arm64 kernel with loads of modules
        and have it "just work" for a variety of platforms (like a distro
        kernel). The big problem turned out to be a lack of dependency
        information between different areas of DT entries, and the work here
        resolves that problem and now allows devices to boot properly, and
        quicker than a monolith kernel.
      
        All of these patches have been in linux-next for a long time with no
        reported issues"

      Pull pin control updates from Linus Walleij:
       "This is the bulk of pin control changes for v5.5.
      
        It is pretty much business as usual, the most interesting thing I
        think is the pin controller for a new Intel chip called Lightning
        Mountain, which is according to news reports some kind of embedded
        network processor and what is surprising about it is that Intel have
        decided to use device tree to describe the system rather than ACPI
        that they have traditionally favored.
      
        Core changes:
      
         - Avoid taking direct references to device tree-supplied device
           names: these may changed at runtime under certain circumstances to
           kstrdup them.
      
        GPIO related:
      
         - Work is ongoing to move to passing the irqchip along as a templated
           struct gpio_irq_chip when adding a standard gpiolib-based irqchip
           to a GPIO controller, a few patches in this cycle switches a few
           pin control drivers over to using this method.
      
        New hardware support:
      
         - Intel Lightning Mountain SoC pin controller and GPIO support, a
           first Intel platform to use device tree rather than ACPI to
           configure the system. News reports says that this SoC is a network
           processor.
      
         - Qualcomm MSM8976 and MSM8956
      
         - Qualcomm PMIC GPIO now also supports PM6150 and PM6150L
      
         - Qualcomm SPMI MPP and SPMI GPIO for PM8950 and PMI8950
      
         - Rockchip RK3308
      
         - Renesas R8A77961
      
         - Allwinner Meson-A1
      
        Driver improvements:
      
         - get_multiple and set_multiple support for the AT91-PIO4 driver.
      
         - Convert Qualcomm SSBI GPIO to use the hierarchical IRQ helpers in
           the GPIOlib irqchip"

       "There have been some significant changes in the core side, both for
        ALSA and ASoC, while lots of development have been seen in SOF, as
        well as many small fixes/improvements for ASoC codecs and platforms.
        Below is a highlight in this cycle:
      
        Core:
         - The unification of PCM vmalloc buffer allocation helpers into the
           standard API
         - Clean up of the default PCM mmap handling for vmalloc & SG-buffer
         - Fix potential races at ALSA timer open
         - A few new PCM API extensions; just preliminary core changes, the
           actual changes in drivers will be merged in 5.6
         - Continued ASoC componentization works; now almost everything is a
           common ASoC component object. A lot of refactoring and
           simplification have been done along with it.
      
        ASoC:
         - Many fixes to the Sound Open Firmware (SOF) code
         - Wake on voice support for Chromebooks
         - SPI support and trigger word detection for RT5677
         - New drivers for Analog Devices ADAU7118, Intel Cannonlake systems
           with RT1011 and RT5682, Texas Instruments TAS2562 and TAS2770
      
        HD-audio:
         - Improved Intel DSP configuration / probe code for SOF
         - Plumbing the legacy HD-audio driver with Intel SOF HDMI
         - DP-MST support for Nvidia HDMI codecs
         - Realtek quirks cleanups and new additions as usual
      
        Others:
         - Lots of refactoring and cleanups for FireWire; period-size sharing,
           h/w IRQ interval configuration, clock recovery improvements, etc
         - USB-audio: Scarlett mixer quirks

      Pull power management updates from Rafael Wysocki:
       "These include cpuidle changes to use nanoseconds (instead of
        microseconds) as the unit of time and to simplify checks for disabled
        idle states in the idle loop, some cpuidle fixes and governor updates,
        assorted cpufreq updates (driver updates mostly and a few core fixes
        and cleanups), devfreq updates (dominated by the tegra30 driver
        changes), new CPU IDs for the RAPL power capping driver, relatively
        minor updates of the generic power domains (genpd) and operation
        performance points (OPP) frameworks, and assorted fixes and cleanups.
      
        There are also two maintainer information updates: Chanwoo Choi will
        be maintaining the devfreq subsystem going forward and Todd Brandt is
        going to maintain the pm-graph utility (created by him).
      
        Specifics:
      
         - Use nanoseconds (instead of microseconds) as the unit of time in
           the cpuidle core and simplify checks for disabled idle states in
           the idle loop (Rafael Wysocki)
      
         - Fix and clean up the teo cpuidle governor (Rafael Wysocki)
      
         - Fix the cpuidle registration error code path (Zhenzhong Duan)
      
         - Avoid excessive vmexits in the ACPI cpuidle driver (Yin Fengwei)
      
         - Extend the idle injection infrastructure to be able to measure the
           requested duration in nanoseconds and to allow an exit latency
           limit for idle states to be specified (Daniel Lezcano)
      
         - Fix cpufreq driver registration and clarify a comment in the
           cpufreq core (Viresh Kumar)
      
         - Add NULL checks to the show() and store() methods of sysfs
           attributes exposed by cpufreq (Kai Shen)
      
         - Update cpufreq drivers:
            * Fix for a plain int as pointer warning from sparse in
              intel_pstate (Jamal Shareef)
            * Fix for a hardcoded number of CPUs and stack bloat in the
              powernv driver (John Hubbard)
            * Updates to the ti-cpufreq driver and DT files to support new
              platforms and migrate bindings from opp-v1 to opp-v2 (Adam Ford,
              H. Nikolaus Schaller)
            * Merging of the arm_big_little and vexpress-spc drivers and

         - Appoint Chanwoo Choi as the new devfreq maintainer.
      
         - Update the devfreq core:
            * Check NULL governor in available_governors_show sysfs to prevent
              showing wrong governor information and fix a race condition
              between devfreq_update_status() and trans_stat_show() (Leonard
              Crestez)
            * Add new 'interrupt-driven' flag for devfreq governors to allow
              interrupt-driven governors to prevent the devfreq core from
              polling devices for status (Dmitry Osipenko)
            * Improve an error message in devfreq_add_device() (Matthias

           framework (Stephen Boyd)
      
         - Avoid freeing memory that has never been allocated in the
           hibernation core (Andy Whitcroft)

         - Misc cleanups, smaller enhancements, fixes.
      
        The load-balancing rework is the most intrusive change: it replaces
        the old heuristics that have become less meaningful after the
        introduction of the PELT metrics, with a grounds-up load-balancing
        algorithm.
      
        As such it's not really an iterative series, but replaces the old
        load-balancing logic with the new one. We hope there are no
        performance regressions left - but statistically it's highly probable
        that there *is* going to be some workload that is hurting from these

      x86/iopl: Make 'struct tss_struct' constant size again · 0bcd7762
      Ingo Molnar authored
      After the following commit:
      
        05b042a1: ("x86/pti/32: Calculate the various PTI cpu_entry_area sizes correctly, make the CPU_ENTRY_AREA_PAGES assert precise")
      
      'struct cpu_entry_area' has to be Kconfig invariant, so that we always
      have a matching CPU_ENTRY_AREA_PAGES size.
      
      This commit added a CONFIG_X86_IOPL_IOPERM dependency to tss_struct:
      
        111e7b15: ("x86/ioperm: Extend IOPL config to control ioperm() as well")
      
      Which, if CONFIG_X86_IOPL_IOPERM is turned off, reduces the size of
      cpu_entry_area by two pages, triggering the assert:
      
        ./include/linux/compiler.h:391:38: error: call to ‘__compiletime_assert_202’ declared with attribute error: BUILD_BUG_ON failed: (CPU_ENTRY_AREA_PAGES+1)*PAGE_SIZE != CPU_ENTRY_AREA_MAP_SIZE
      
      Simplify the Kconfig dependencies and make cpu_entry_area constant
      size on 32-bit kernels again.
      
      Fixes: 05b042a1: ("x86/pti/32: Calculate the various PTI cpu_entry_area sizes correctly, make the CPU_ENTRY_AREA_PAGES assert precise")

      Revert "vfs: properly and reliably lock f_pos in fdget_pos()" · 2be7d348
      Linus Torvalds authored
      This reverts commit 0be0ee71.
      
      I was hoping it would be benign to switch over entirely to FMODE_STREAM,
      and we'd have just a couple of small fixups we'd need, but it looks like
      we're not quite there yet.
      
      While it worked fine on both my desktop and laptop, they are fairly
      similar in other respects, and run mostly the same loads.  Kenneth
      Crudup reports that it seems to break both his vmware installation and
      the KDE upower service.  In both cases apparently leading to timeouts
      due to waitinmg for the f_pos lock.
      
      There are a number of character devices in particular that definitely
      want stream-like behavior, but that currently don't get marked as
      streams, and as a result get the exclusion between concurrent
      read()/write() on the same file descriptor.  Which doesn't work well for
      them.
      
      The most obvious example if this is /dev/console and /dev/tty, which use
      console_fops and tty_fops respectively (and ptmx_fops for the pty master
      side).  It may be that it's just this that causes problems, but we
      clearly weren't ready yet.
      
      Because there's a number of other likely common cases that don't have
      llseek implementations and would seem to act as stream devices:
      
        /dev/fuse		(fuse_dev_operations)
        /dev/mcelog		(mce_chrdev_ops)
        /dev/mei0		(mei_fops)
        /dev/net/tun		(tun_fops)
        /dev/nvme0		(nvme_dev_fops)
        /dev/tpm0		(tpm_fops)
        /proc/self/ns/mnt	(ns_file_operations)
        /dev/snd/pcm*		(snd_pcm_f_ops[])
      
      and while some of these could be trivially automatically detected by the
      vfs layer when the character device is opened by just noticing that they
      have no read or write operations either, it often isn't that obvious.
      
      Some character devices most definitely do use the file position, even if
      they don't allow seeking: the firmware update code, for example, uses
      simple_read_from_buffer() that does use f_pos, but doesn't allow seeking
      back and forth.
      
      We'll revisit this when there's a better way to detect the problem and
      fix it (possibly with a coccinelle script to do more of the FMODE_STREAM
      annotations).

      Pull x86 iopl updates from Ingo Molnar:
       "This implements a nice simplification of the iopl and ioperm code that
        Thomas Gleixner discovered: we can implement the IO privilege features
        of the iopl system call by using the IO permission bitmap in
        permissive mode, while trapping CLI/STI/POPF/PUSHF uses in user-space
        if they change the interrupt flag.
      
        This implements that feature, with testing facilities and related
        cleanups"
      
      [ "Simplification" may be an over-statement. The main goal is to avoid
        the cli/sti of iopl by effectively implementing the IO port access
        parts of iopl in terms of ioperm.
      
        This may end up not workign well in case people actually depend on
        cli/sti being available, or if there are mixed uses of iopl and
        ioperm. We will see..       - Linus ]

      Linus Torvalds authored
      Pull x86 boot updates from Ingo Molnar:
       "The main changes were:
      
         - Extend the boot protocol to allow future extensions without hitting
           the setup_header size limit.
      
         - Add quirk to devicetree systems to disable the RTC unless it's
           listed as a supported device.
      
         - Fix ld.lld linker pedantry"
      
      * 'x86-boot-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
        x86/boot: Introduce setup_indirect
        x86/boot: Introduce kernel_info.setup_type_max
        x86/boot: Introduce kernel_info
        x86/init: Allow DT configured systems to disable RTC at boot time
        x86/realmode: Explicitly set entry point via ENTRY in linker script

      Merge branches 'core-objtool-for-linus', 'x86-cleanups-for-linus' and 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
      
      Pull x86 objtool, cleanup, and apic updates from Ingo Molnar:
       "Objtool:
      
         - Fix a gawk 5.0 incompatibility in gen-insn-attr-x86.awk. Most
           distros are still on gawk 4.2.x.
      
        Cleanup:
      
         - Misc cleanups, plus the removal of obsolete code such as Calgary
           IOMMU support, which code hasn't seen any real testing in a long
           time and there's no known users left.
      
        apic:
      
         - Two changes: a cleanup and a fix for an (old) race for oneshot
           threaded IRQ handlers"
      
      * 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:

        x86/pci: Remove #ifdef __KERNEL__ guard from <asm/pci.h>
        x86/pci: Remove pci_64.h
        x86: Remove the calgary IOMMU driver
        x86/apic, x86/uprobes: Correct parameter names in kernel-doc comments

        x86/nmi: Remove stale EDAC include leftover
      
      * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
