      arm64: Fix show_unhandled_signal_ratelimited usage · f871d268
      Suzuki K. Poulose authored
      Commit 86dca36e introduced ratelimited usage for
      'unhandled_signal' messages.
      The commit checks the ratelimit irrespective of whether
      the signal is handled or not, which is wrong and leads
      to false reports like the below in dmesg :
      
      __do_user_fault: 127 callbacks suppressed
      
      Do the ratelimit check only if the signal is unhandled.
      
      Fixes: 86dca36e ("arm64: use private ratelimit state along with show_unhandled_signals")

      ARM64 / SMP: Switch pr_err() to pr_debug() for disabled GICC entry · f9058929
      Hanjun Guo authored
      It is normal that firmware presents GICC entry or entries (processors)
      with disabled flag in ACPI MADT, taking a system of 16 cpus for example,
      ACPI firmware may present 8 ebabled first with another 8 cpus disabled
      in MADT, the disabled cpus can be hot-added later.
      
      Firmware may also present more cpus than the hardware actually has, but
      disabled the unused ones, and easily enable it when the hardware has such
      cpus to make the firmware code scalable.
      
      So that's not an error for disabled cpus in MADT, we can switch pr_err()
      to pr_debug() to make the boot a little quieter by default.
      
      Since hwid for disabled cpus often are invalid, and we check invalid hwid
      first in the code, for use case that hot add cpus later will be filtered
      out and will not be counted in possible cups, so move this check before
      the hwid one to prepare the code to count for disabeld cpus when cpu
      hot-plug is introduced.

      Linus Torvalds authored
      Pull ACPICA updates from Rafael Wysocki:
       "Additional ACPICA material for v4.2-rc1
      
        This will update the ACPICA code in the kernel to upstream revision
        20150619 (a bug-fix release mostly including stable-candidate fixes)
        and restore an earlier ACPICA commit that had to be reverted due to a
        regression introduced by it (the regression is addressed by
        blacklisting the only known system affected by it to date).
      
        The only new feature added by this update is the support for
        overriding objects in the ACPI namespace and a new ACPI table that can
        be used for that called the Override System Definition Table (OSDT).
        That should allow us to "patch" the ACPI namespace built from
        incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
        during system startup without the need to provide replacements for all
        of those tables in the future.
      
        Specifics:
      
         - Fix system resume problems related to 32-bit and 64-bit versions of
           the Firmware ACPI Control Structure (FACS) in the firmare (Lv
           Zheng)
      
         - Fix double initialization of the FACS (Lv Zheng)
      
         - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)
      
         - Add support for the (currently missing) new GIC version field in
           the Multiple APIC Description Table (MADT) (Hanjun Guo)
      
         - Add support for overriding objects in the ACPI namespace to ACPICA
           and OSDT support (Lv Zheng, Bob Moore, Zhang Rui)
      
         - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore)
      
         - Restore the commit modifying _REV to always return "2" (as required
           by ACPI 6) and add a blacklisting mechanism for systems that may be
           affected by that change (Rafael J Wysocki)
      
         - Assorted fixes and cleanups (Bob Moore, Lv Zheng, Sascha Wildner)"

      ACPI / init: Make it possible to override _REV · 18d78b64
      Rafael J. Wysocki authored
      The platform firmware on some systems expects Linux to return "5" as
      the supported ACPI revision which makes it expose system configuration
      information in a special way.
      
      For example, based on what ACPI exports as the supported revision,
      Dell XPS 13 (2015) configures its audio device to either work in HDA
      mode or in I2S mode, where the former is supposed to be used on Linux
      until the latter is fully supported (in the kernel as well as in user
      space).
      
      Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later
      is supported by the OS, a subsequent change will make that happen, so
      make it possible to override that on systems where "5" is expected to
      be returned for Linux to work correctly one them (such as the Dell
      machine mentioned above).

      [IA64] Drop debug test/printk that some special pages are marked reserved · 43c518d1
      Tony Luck authored
      In commit 92923ca3 "mm: meminit: only set page reserved in the memblock region"
      we dropped setting the reserved bits for all pages. This results in some warnings
      on ia64:
      
      put_kernel_page: page at 0xe000000005588000 not in reserved memory
      put_kernel_page: page at 0xe000000005588000 not in reserved memory
      put_kernel_page: page at 0xe000000005580000 not in reserved memory
      put_kernel_page: page at 0xe000000005580000 not in reserved memory
      put_kernel_page: page at 0xe000000005580000 not in reserved memory
      put_kernel_page: page at 0xe000000005580000 not in reserved memory
      
      the two different pages match up with two objects from the loaded kernel
      that get mapped by arch/ia64/mm/init.c:setup_gate()
      
      a000000101588000 D __start_gate_section

      In a discussion with Mel Gorman:
        http://lkml.kernel.org/r/20150526102219.GB13750%40suse.de
      he suggested that while the preferred approach might be to
      set the reserved bit for these pages, it would also be OK
      to just drop the test:
         "as it's a debugging check that is ia-64 specific"
      
      After hunting around a bit and failin to find a good place to mark these
      pages as reserved - I decided to just delete the test.

       "Replace module_platform_driver with builtin_platform driver in non
        modules.
      
        We see an increasing number of non-modular drivers using
        modular_driver() type register functions.  There are several downsides
        to letting this continue unchecked:
      
         - The code can appear modular to a reader of the code, and they won't
           know if the code really is modular without checking the Makefile
           and Kconfig to see if compilation is governed by a bool or
           tristate.
      
         - Coders of drivers may be tempted to code up an __exit function that
           is never used, just in order to satisfy the required three args of
           the modular registration function.
      
         - Non-modular code ends up including the <module.h> which increases
           CPP overhead that they don't need.
      
         - It hinders us from performing better separation of the module init
           code and the generic init code.
      
        So here we introduce similar macros for builtin drivers.  Then we
        convert builtin drivers (controlled by a bool Kconfig) by making the
        following type of mapping:
      
          module_platform_driver()       --->  builtin_platform_driver()
          module_platform_driver_probe() --->  builtin_platform_driver_probe().
      
        The set of drivers that are converted here are just the ones that
        showed up as relying on an implicit include of <module.h> during a
        pending header cleanup.  So we convert them here vs adding an include
        of <module.h> to non-modular code to avoid compile fails.  Additonal
        conversions can be done asynchronously at any time.
      
        Once again, an unused module_exit function that is removed here
        appears in the diffstat as an outlier wrt all the other changes"

      Pull module_init replacement part two from Paul Gortmaker:
       "Replace module_init with appropriate alternate initcall in non
        modules.
      
        This series converts non-modular code that is using the module_init()
        call to hook itself into the system to instead use one of our
        alternate priority initcalls.
      
        Unlike the previous series that used device_initcall and hence was a
        runtime no-op, these commits change to one of the alternate initcalls,
        because (a) we have them and (b) it seems like the right thing to do.
      
        For example, it would seem logical to use arch_initcall for arch
        specific setup code and fs_initcall for filesystem setup code.
      
        This does mean however, that changes in the init ordering will be
        taking place, and so there is a small risk that some kind of implicit
        init ordering issue may lie uncovered.  But I think it is still better
        to give these ones sensible priorities than to just assign them all to
        device_initcall in order to exactly preserve the old ordering.
      
        Thad said, we have already made similar changes in core kernel code in
        commit c96d6660 ("kernel: audit/fix non-modular users of
        module_init in core code") without any regressions reported, so this
        type of change isn't without precedent.  It has also got the same

        This series of commits converts non-modular code that is using the

        The conversion is a runtime no-op, since module_init actually becomes

        device_initcall.  A couple files show a larger negative diffstat,
        representing ones that had a module_exit function that we remove here

      Pull __cpuinit removal from Paul Gortmaker:
       "Remove __cpuinit macros and users.
      
        We removed the __cpuinit stuff in 3.11-rc1 with commit 22f0a273
        ("init.h: remove __cpuinit sections from the kernel") but we left some
        no-op stubs as a courtesy to unmerged code.
      
        Here we get rid of the stubs as well, since (as can be seen in these
        changes) they are enabling use cases to sneak back in, primarily from
        older BSP code that has been living out of tree for some time prior to
        getting mainlined.  So we get rid of these "new" users 1st and then
        get rid of the stubs.
      
        Obviously, getting rid of the stubs can't happen until all the users
        are gone, so I had to keep this together as a series, even though some
        of these commits since got picked up into maintainers trees as well.
      
        The nature of this change is such that it should have zero impact on
        the generated runtime.
      
        This is one of several independent cleanup branches aimed at enabling
        better organization in the init.h and module.h code.  They have been
        getting coverage in the linux-next tree for the last month, in
        addition to my local testing, which also covers approximately a half

      NVMe: Fix irq freeing when queue_request_irq fails · 758dd7fd
      Jon Derrick authored
      Fixes an issue when queue_reuest_irq fails in nvme_setup_io_queues. This
      patch initializes all vectors to -1 and resets the vector to -1 in the
      case of a failure in queue_request_irq. This avoids the free_irq in
      nvme_suspend_queue if the queue did not get an irq.

      writeback: don't drain bdi_writeback_congested on bdi destruction · a20135ff
      Tejun Heo authored
      52ebea74 ("writeback: make backing_dev_info host cgroup-specific
      bdi_writebacks") made bdi (backing_dev_info) host per-cgroup wb's
      (bdi_writeback's).  As the congested state needs to be per-wb and
      referenced from blkcg side and multiple wbs, the patch made all
      non-root cong's (bdi_writeback_congested's) reference counted and
      indexed on bdi.
      
      When a bdi is destroyed, cgwb_bdi_destroy() tries to drain all
      non-root cong's; however, this can hang indefinitely because wb's can
      also be referenced from blkcg_gq's which are destroyed after bdi
      destruction is complete.
      
      This patch fixes the bug by updating bdi destruction to not wait for
      cong's to drain.  A cong is unlinked from bdi->cgwb_congested_tree on
      bdi destuction regardless of its reference count as the bdi may go
      away any point after destruction.  wb_congested_put() checks whether
      the cong is already unlinked on release.

      writeback: don't embed root bdi_writeback_congested in bdi_writeback · a13f35e8
      Tejun Heo authored

      also be referenced from blkcg_gq's which are destroyed after bdi
      destruction is complete.
      
      To fix the bug, bdi destruction will be updated to not wait for cong's
      to drain, which naturally means that cong's may outlive the associated
      bdi.  This is fine for non-root cong's but is problematic for the root
      cong's which are embedded in their bdi's as they may end up getting
      dereferenced after the containing bdi's are freed.
      
      This patch makes root cong's behave the same as non-root cong's.  They
      are no longer embedded in their bdi's but allocated separately during
      bdi initialization, indexed and reference counted the same way.
      
      * As cong handling is the same for all wb's, wb->congested
        initialization is moved into wb_init().
      
      * When !CONFIG_CGROUP_WRITEBACK, there was no indexing or refcnting.
        bdi->wb_congested is now a pointer pointing to the root cong
        allocated during bdi init and minimal refcnting operations are
        implemented.
      
      * The above makes root wb init paths diverge depending on
        CONFIG_CGROUP_WRITEBACK.  root wb init is moved to cgwb_bdi_init().
      
      This patch in itself shouldn't cause any consequential behavior
      differences but prepares for the actual fix.

      OMAPDSS: fix probing if rfbi device is enabled · 0438ec90
      Tomi Valkeinen authored
      After the commit 736e60dd ("OMAPDSS:
      componentize omapdss") the dss core device will wait until all the
      subdevices have been successfully probed. However, we don't have a
      working driver for RFBI, so if RFBI device exists, omapdss will never
      get probed.
      
      All the .dtsi files set RFBI as disabled, except am4372.dtsi. This
      causes omapdss probe to not finish on AM4 devices.
      
      This patch makes omapdss driver skip adding rfbi device as a
      subcomponent, solving the issue.
      
      This should be reverted when we have a working RFBI driver.
