      tracing: Fix tick_stop tracepoint symbols for user export · c87edb36
      Steven Rostedt (Red Hat) authored
      The symbols used in the tick_stop tracepoint were not being converted
      properly into integers in the trace_stop format file. Instead we had this:
      
      print fmt: "success=%d dependency=%s", REC->success,
          __print_symbolic(REC->dependency, { 0, "NONE" },
           { (1 << TICK_DEP_BIT_POSIX_TIMER), "POSIX_TIMER" },
           { (1 << TICK_DEP_BIT_PERF_EVENTS), "PERF_EVENTS" },
           { (1 << TICK_DEP_BIT_SCHED), "SCHED" },
           { (1 << TICK_DEP_BIT_CLOCK_UNSTABLE), "CLOCK_UNSTABLE" })
      
      User space tools have no idea how to parse "TICK_DEP_BIT_SCHED" or the other
      symbols used to do the bit shifting. The reason is that the conversion was
      done with using the TICK_DEP_MASK_* symbols which are just macros that
      convert to the BIT shift itself (with the exception of NONE, which was
      converted properly, because it doesn't use bits, and is defined as zero).
      
      The TICK_DEP_BIT_* needs to be denoted by TRACE_DEFINE_ENUM() in order to
      have this properly converted for user space tools to parse this event.

      Disable "frame-address" warning · 124a3d88
      Linus Torvalds authored
      Newer versions of gcc warn about the use of __builtin_return_address()
      with a non-zero argument when "-Wall" is specified:
      
        kernel/trace/trace_irqsoff.c: In function ‘stop_critical_timings’:
        kernel/trace/trace_irqsoff.c:433:86: warning: calling ‘__builtin_return_address’ with a nonzero argument is unsafe [-Wframe-address]
           stop_critical_timing(CALLER_ADDR0, CALLER_ADDR1);
        [ .. repeats a few times for other similar cases .. ]
      
      It is true that a non-zero argument is somewhat dangerous, and we do not
      actually have very many uses of that in the kernel - but the ftrace code
      does use it, and as Stephen Rostedt says:
      
       "We are well aware of the danger of using __builtin_return_address() of
        > 0.  In fact that's part of the reason for having the "thunk" code in
        x86 (See arch/x86/entry/thunk_{64,32}.S).  [..] it adds extra frames
        when tracking irqs off sections, to prevent __builtin_return_address()
        from accessing bad areas.  In fact the thunk_32.S states: 'Trampoline to
        trace irqs off.  (otherwise CALLER_ADDR1 might crash)'."
      
      For now, __builtin_return_address() with a non-zero argument is the best
      we can do, and the warning is not helpful and can end up making people
      miss other warnings for real problems.
      
      So disable the frame-address warning on compilers that need it.

         - A fix for locking issues when external drivers explicitly locked

           Confusion between these two caused us to have scenarios where we
           were dropping locks.  These are fixed by splitting into two
           separate locks like should have been done originally, making

      Disable "maybe-uninitialized" warning globally · 6e8d666e
      Linus Torvalds authored
      Several build configurations had already disabled this warning because
      it generates a lot of false positives.  But some had not, and it was
      still enabled for "allmodconfig" builds, for example.
      
      Looking at the warnings produced, every single one I looked at was a
      false positive, and the warnings are frequent enough (and big enough)
      that they can easily hide real problems that you don't notice in the
      noise generated by -Wmaybe-uninitialized.
      
      The warning is good in theory, but this is a classic case of a warning
      that causes more problems than the warning can solve.
      
      If gcc gets better at avoiding false positives, we may be able to
      re-enable this warning.  But as is, we're better off without it, and I
      want to be able to see the *real* warnings.

        is fully working, reviewed and ready for merge and be used by other
        filesystems.
      
        There are a lot of other fixes and cleanups in the tree, but those are

        separate to all the "normal" pull request changes so they don't get

      ipmi: remove trydefaults parameter and default init · b07b58a3
      Tony Camuso authored
      Parameter trydefaults=1 causes the ipmi_init to initialize ipmi through
      the legacy port io space that was designated for ipmi. Architectures
      that do not map legacy port io can panic when trydefaults=1.
      
      Rather than implement build-time conditional exceptions for each
      architecture that does not map legacy port io, we have removed legacy
      port io from the driver.
      
      Parameter 'trydefaults' has been removed. Attempts to use it hereafter
      will evoke the "Unknown symbol in module, or unknown parameter" message.
      
      The patch was built against a number of architectures and tested for
      regressions and functionality on x86_64 and ARM64.

      arm64: arm: Fix-up the removal of the arm64 regs_query_register_name() prototype · fd6380b7
      Catalin Marinas authored
      Commit 0a8ea52c ("arm64: Add HAVE_REGS_AND_STACK_ACCESS_API
      feature") inadvertently removed the arch/arm prototype instead of the
      arm64 one introduced by the original patch. There should not be any
      bisection issues since this function is not called from anywhere else
      (it could as well be removed from arch/arm at some point).

      be2net: perform temperature query in adapter regardless of its interface state · d3480615
      Guilherme G. Piccoli authored
      The be2net driver performs fw temperature queries on be_worker() routine,
      which is executed each second for each be_adapter. There is a frequency
      threshold to avoid fw query to happens at each call to be_worker();
      instead, currently a fw query occurs once in 64 runs of the procedure.
      
      Nevertheless, this fw temperature query is invoked only for adapters which
      interface is up, so we can see I/O errors on read of hwmon counters from
      userspace (from tools like lm-sensors) in case we have adapters' functions
      which interface is down.
      
      This patch moves the fw query code to be invoked even if interface is down.
      No functional changes were introduced.

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.8 kernel cycle.  The big
        news is the completion of the chardev ABI which I'm very happy about
        and apart from that it's an ordinary, quite busy cycle.  The details
        are below.
      
        The patches are tested in linux-next for some time, patches to other
        subsystem mostly have ACKs.
      
        I got overly ambitious with configureing lines as input for IRQ lines
        but it turns out that some controllers have their interrupt-enable and
        input-enabling in orthogonal settings so the assumption that all IRQ
        lines are input lines does not hold.  Oh well, revert and back to the
        drawing board with that.
      
        Core changes:
      
         - The big item is of course the completion of the character device
           ABI.  It has now replaced and surpassed the former unmaintainable
           sysfs ABI: we can now hammer (bitbang) individual lines or sets of
           lines and read individual lines or sets of lines from userspace,
           and we can also register to listen to GPIO events from userspace.
      
           As a tie-in we have two new tools in tools/gpio: gpio-hammer and
           gpio-event-mon that illustrate the proper use of the new ABI.  As
           someone said: the wild west days of GPIO are now over.
      
         - Continued to remove the pointless ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIB
           Kconfig symbols.  I'm patching hexagon, openrisc, powerpc, sh,
           unicore, ia64 and microblaze.  These are either ACKed by their
           maintainers or patched anyways after a grace period and no response
           from maintainers.
      
           Some archs (ARM) come in from their trees, and others (x86) are
           still not fixed, so I might send a second pull request to root it
           out later in this merge window, or just defer to v4.9.
      
         - The GPIO tools are moved to the tools build system.
      
        New drivers:
      
         - New driver for the MAX77620/MAX20024.
      
         - New driver for the Intel Merrifield.
      
         - Enabled PCA953x for the TI PCA9536.
      
         - Enabled PCA953x for the Intel Edison.
      
         - Enabled R8A7792 in the RCAR driver.
      
        Driver improvements:
      
         - The STMPE and F7188x now supports the .get_direction() callback.
      
         - The Xilinx driver supports setting multiple lines at once.
      
         - ACPI support for the Vulcan GPIO controller.
      
         - The MMIO GPIO driver supports device tree probing.
      
         - The Acer One 10 is supported through the _DEP ACPI attribute.
      
        Cleanups:
      
         - A major cleanup of the OF/DT support code.  It is way easier to
           read and understand now, probably this improves performance too.
      
         - Drop a few redundant .owner assignments.
      
         - Remove CLPS711x boardfile support: we are 100% DT"

      Pull ACPI updates from Rafael Wysocki:
       "The new feaures here are the support for ACPI overlays (allowing ACPI
        tables to be loaded at any time from EFI variables or via configfs)
        and the LPI (Low-Power Idle) support.  Also notable is the ACPI-based
        NUMA support for ARM64.
      
        Apart from that we have two new drivers, for the DPTF (Dynamic Power
        and Thermal Framework) power participant device and for the Intel
        Broxton WhiskeyCove PMIC, some more PMIC-related changes, support for
        the Boot Error Record Table (BERT) in APEI and support for
        platform-initiated graceful shutdown.
      
        Plus two new pieces of documentation and usual assorted fixes and
        cleanups in quite a few places.
      
        Specifics:
      
         - Support for ACPI SSDT overlays allowing Secondary System
           Description Tables (SSDTs) to be loaded at any time from EFI
           variables or via configfs (Octavian Purdila, Mika Westerberg).
      
         - Support for the ACPI LPI (Low-Power Idle) feature introduced in
           ACPI 6.0 and allowing processor idle states to be represented in
           ACPI tables in a hierarchical way (with the help of Processor
           Container objects) and support for ACPI idle states management on
           ARM64, based on LPI (Sudeep Holla).
      
         - General improvements of ACPI support for NUMA and ARM64 support for
           ACPI-based NUMA (Hanjun Guo, David Daney, Robert Richter).
      
         - General improvements of the ACPI table upgrade mechanism and ARM64
           support for that feature (Aleksey Makarov, Jon Masters).
      
         - Support for the Boot Error Record Table (BERT) in APEI and
           improvements of kernel messages printed by the error injection code
           (Huang Ying, Borislav Petkov).
      
         - New driver for the Intel Broxton WhiskeyCove PMIC operation region
           and support for the REGS operation region on Broxton, PMIC code
           cleanups (Bin Gao, Felipe Balbi, Paul Gortmaker).
      
         - New driver for the power participant device which is part of the
           Dynamic Power and Thermal Framework (DPTF) and DPTF-related code
           reorganization (Srinivas Pandruvada).
      
         - Support for the platform-initiated graceful shutdown feature
           introduced in ACPI 6.1 (Prashanth Prakash).
      
         - ACPI button driver update related to lid input events generated
           automatically on initialization and system resume that have been
           problematic for some time (Lv Zheng).
      
         - ACPI EC driver cleanups (Lv Zheng).
      
         - Documentation of the ACPICA release automation process and the
           in-kernel ACPI AML debugger (Lv Zheng).
      
         - New blacklist entry and two fixes for the ACPI backlight driver
           (Alex Hung, Arvind Yadav, Ralf Gerbig).
      
         - Cleanups of the ACPI pci_slot driver (Joe Perches, Paul Gortmaker).
      
         - ACPI CPPC code changes to make it more robust against possible
           defects in ACPI tables and new symbol definitions for PCC (Hoan
           Tran).
      
         - System reboot code modification to execute the ACPI _PTS (Prepare
           To Sleep) method in addition to _TTS (Ocean He).
      
         - ACPICA-related change to carry out lock ordering checks in ACPICA
           if ACPICA debug is enabled in the kernel (Lv Zheng).
      
         - Assorted minor fixes and cleanups (Andy Shevchenko, Baoquan He,
           Bhaktipriya Shridhar, Paul Gortmaker, Rafael Wysocki)"
