      MIPS: Undefine PMD_ORDER for 32-bit builds · 7176b6ac
      Daniel Silsby authored
      During an update long ago to conform to 4-level page code, PMD_ORDER was
      changed from 0 to 1, despite the fact that a PMD table is not used at
      all in a 32-bit MIPS build. PMD_ORDER does not seem to be used in these
      builds. Now, it matches PUD_ORDER, a nonsense #define to give a build
      failure with informative error.
      
      The older commit that had redefined PMD_ORDER was
      commit c6e8b587 ("Update MIPS to use the 4-level pagetable code
      thereby getting rid of the compacrapability headers.")

      MIPS: Add partial 32-bit huge page support · 35476311
      Daniel Silsby authored
       This adds initial support for huge pages to 32-bit MIPS systems.
      Systems with extended addressing enabled (EVA,XPA,Alchemy/Netlogic)
      are not yet supported.
       With huge pages enabled, this implementation will increase page table
      memory overhead to match that of a 64-bit MIPS system. However, the
      cache-friendliness of page table walks is not affected significantly.

      MIPS: Disallow CPU_SUPPORTS_HUGEPAGES for XPA,EVA · 171543e7
      Daniel Silsby authored
      In preparation for 32-bit MIPS huge page support.
      
      EVA,XPA are extended-addressing modes for 32-bit MIPS systems. Because
      huge pages aren't currently supported in 32-bit MIPS, this doesn't take
      any features away from EVA,XPA-enabled systems. However, the soon-to-
      come 32-bit MIPS huge page support doesn't yet support them.
      
      This also disables CPU_SUPPORTS_HUGEPAGES for the small number of 32-bit
      MIPS CPUs from Alchemy/Netlogic that support a custom 36-bit extended
      addressing. It's unknown if they even support huge pages in hardware.

      dt-bindings: riscv: Limit cpus schema to only check RiscV 'cpu' nodes · 7d9ef7f3
      Rob Herring authored
      Matching on the 'cpus' node was a bad choice because the schema is
      incorrectly applied to non-RiscV cpus nodes. As we now have a common cpus
      schema which checks the general structure, it is also redundant to do so
      in the Risc-V CPU schema.
      
      The downside is one could conceivably mix different architecture's cpu
      nodes or have typos in the compatible string. The latter problem pretty
      much exists for every schema.

      dt-bindings: Ensure child nodes are of type 'object' · 15ffef1a
      Rob Herring authored
      Properties which are child node definitions need to have an explict
      type. Otherwise, a matching (DT) property can silently match when an
      error is desired. Fix this up tree-wide. Once this is fixed, the
      meta-schema will enforce this on any child node definitions.

      Pull CONFIG_PREEMPT_RT stub config from Thomas Gleixner:
       "The real-time preemption patch set exists for almost 15 years now and
        while the vast majority of infrastructure and enhancements have found
        their way into the mainline kernel, the final integration of RT is
        still missing.
      
        Over the course of the last few years, we have worked on reducing the
        intrusivenness of the RT patches by refactoring kernel infrastructure
        to be more real-time friendly. Almost all of these changes were
        benefitial to the mainline kernel on their own, so there was no
        objection to integrate them.
      
        Though except for the still ongoing printk refactoring, the remaining
        changes which are required to make RT a first class mainline citizen
        are not longer arguable as immediately beneficial for the mainline
        kernel. Most of them are either reordering code flows or adding RT
        specific functionality.
      
        But this now has hit a wall and turned into a classic hen and egg
        problem:
      
           Maintainers are rightfully wary vs. these changes as they make only
           sense if the final integration of RT into the mainline kernel takes
           place.
      
        Adding CONFIG_PREEMPT_RT aims to solve this as a clear sign that RT
        will be fully integrated into the mainline kernel. The final
        integration of the missing bits and pieces will be of course done with
        the same careful approach as we have used in the past.
      
        While I'm aware that you are not entirely enthusiastic about that, I
        think that RT should receive the same treatment as any other widely
        used out of tree functionality, which we have accepted into mainline
        over the years.
      
        RT has become the de-facto standard real-time enhancement and is
        shipped by enterprise, embedded and community distros. It's in use
        throughout a wide range of industries: telecommunications, industrial
        automation, professional audio, medical devices, data acquisition,
        automotive - just to name a few major use cases.
      
        RT development is backed by a Linuxfoundation project which is
        supported by major stakeholders of this technology. The funding will
        continue over the actual inclusion into mainline to make sure that the
        functionality is neither introducing regressions, regressing itself,
        nor becomes subject to bitrot. There is also a lifely user community
        around RT as well, so contrary to the grim situation 5 years ago, it's
        a healthy project.
      
        As RT is still a good vehicle to exercise rarely used code paths and
        to detect hard to trigger issues, you could at least view it as a QA
        tool if nothing else"

      Pull more Kbuild updates from Masahiro Yamada:
      
       - match the directory structure of the linux-libc-dev package to that
         of Debian-based distributions
      
       - fix incorrect include/config/auto.conf generation when Kconfig
         creates it along with the .config file
      
       - remove misleading $(AS) from documents
      
       - clean up precious tag files by distclean instead of mrproper
      
       - add a new coccinelle patch for devm_platform_ioremap_resource
         migration
      
       - refactor module-related scripts to read modules.order instead of
         $(MODVERDIR)/*.mod files to get the list of created modules
      
       - remove MODVERDIR
      
       - update list of header compile-test
      
       - add -fcf-protection=none flag to avoid conflict with the retpoline
         flags when CONFIG_RETPOLINE=y
      
       - misc cleanups

      Pull dcache and mountpoint updates from Al Viro:
       "Saner handling of refcounts to mountpoints.
      
        Transfer the counting reference from struct mount ->mnt_mountpoint
        over to struct mountpoint ->m_dentry. That allows us to get rid of the
        convoluted games with ordering of mount shutdowns.
      
        The cost is in teaching shrink_dcache_{parent,for_umount} to cope with
        mixed-filesystem shrink lists, which we'll also need for the Slab
        Movable Objects patchset"
      
      * 'work.dcache2' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs:
        switch the remnants of releasing the mountpoint away from fs_pin
        get rid of detach_mnt()
        make struct mountpoint bear the dentry reference to mountpoint, not struct mount
        Teach shrink_dcache_parent() to cope with mixed-filesystem shrink lists
        fs/namespace.c: shift put_mountpoint() to callers of unhash_mnt()
        __detach_mounts(): lookup_mountpoint() can't return ERR_PTR() anymore
        nfs: dget_parent() never returns NULL
        ceph: don't open-code the check for dead lockref
