        An input queue and a processing queue is split out from the monolithic
        fuse connection, each of those having their own spinlock.  The end of
        the patchset adds the ability to clone a fuse connection.  This means,
        that instead of having to read/write requests/answers on a single fuse
        device fd, the fuse daemon can have multiple distinct file descriptors
        open.  Each of those can be used to receive requests and send answers,
        currently the only constraint is that a request must be answered on
        the same fd as it was read from.
      
        This can be extended further to allow binding a device clone to a
        specific CPU or NUMA node.

        What started as a removal of no longer required include <linux/init.h>
        due to the earlier __cpuinit and __devinit removal led to the
        observation that some module specfic support was living in init.h

        regressions.

      Pull module_platform_driver replacement from Paul Gortmaker:
       "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
        local testing and linux-next coverage as all the other pull requests
        that I'm sending for this merge window have got.

      Pull module_init replacement part one from Paul Gortmaker:
       "Replace module_init with equivalent device_initcall in non modules.
      
        This series of commits converts non-modular code that is using the
        module_init() call to hook itself into the system to instead use
        device_initcall().
      
        The conversion is a runtime no-op, since module_init actually becomes
        __initcall in the non-modular case, and that in turn gets mapped onto
        device_initcall.  A couple files show a larger negative diffstat,
        representing ones that had a module_exit function that we remove here
        vs previously relying on the linker to dispose of it.
      
        We make this conversion now, so that we can relocate module_init from
        init.h into module.h in the future.
      
        The files changed here are just limited to those that would otherwise
        have to add module.h to obviously non-modular code, in order to avoid

       "Fix up implicit <module.h> users that will break later.
      
        The files changed here are simply modular source files that are
        implicitly relying on <module.h> being present.  We fix them up now,
        so that we can decouple some of the module related init code from the
        core init code in the future.
      
        The addition of the module.h include to several files here is also a
        no-op from a code generation point of view, else there would already
        be compile issues with these files today.
      
        There may be lots more implicit includes of <module.h> in tree, but
        these are the ones that extensive build test coverage has shown that
        must be fixed in order to avoid build breakage fallout for the pending
        module.h <---> init.h code relocation we desire to complete"

      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
        dozen or more architectures"

       "Four fixes have queued up to fix regressions introduced after v4.1:
      
         - Don't fail IOMMU driver initialization when the add_device
           call-back returns -ENODEV, as that just means that the device is
           not translated by the IOMMU.  This is pretty common on ARM.
      
         - Two fixes for the ARM-SMMU driver for a wrong feature check and to
           remove a redundant NULL check.
      
         - A fix for the AMD IOMMU driver to fix a boot panic on systems where

      The problem is almost exactly the same as the one fixed by feaff8e5.
      We must take a reference to the struct file when running the LOCKU
      compound to prevent the final fput from running until the operation is
      complete.

      watchdog: omap_wdt: early_enable module parameter · b2102eb3
      Lars Poeschel authored
      Add a early_enable module parameter to the omap_wdt that starts the
      watchdog on module insertion. The default value is 0 which does not
      start the watchdog - which also does not change the behavior if the
      parameter is not given.
