      docs: update references to the device io book · 0fe397f0
      Helmut Grohne authored
      While converting the deviceiobook from DocBook to RST, dangling
      references were left behind. This commit updates all remaining
      references to the new location. SeongJae Park improved the ko_KR
      translation.

        here are smaller changes for new hardware on existing platforms, and
        there are a few larger changes worth pointing out.
      
        Major new platforms:
      
         - Gemini has been ported to DT, so a handful of "new" platforms moved
           over from board files
      
         - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288
           SoM and RDK
      
         - A bunch of embedded platforms, several Linksys platforms, Synology
           DS116,
      
         - Motorola Droid4 (really old OMAP-based phone) support is added.
      
        Some refactorings, i.e. Allwinner H3/H5 support is commonalized.
      
        And lots of smaller changes, cleanups, etc. See shortlog for more
        description
      
        We're adding ability to cross-include DT files between arm and arm64,
        by creating appropriate links in the dt-include directory, and using
        arm/ and arm64/ as include prefixes. This will avoid other local hacks
        such as per-file links between the two arch trees (this broke for
        external mirroring of DT contents). Now they can just provide their

      proc: try to remove use of FOLL_FORCE entirely · 8ee74a91
      Linus Torvalds authored
      We fixed the bugs in it, but it's still an ugly interface, so let's see
      if anybody actually depends on it.  It's entirely possible that nothing
      actually requires the whole "punch through read-only mappings"
      semantics.
      
      For example, gdb definitely uses the /proc/<pid>/mem interface, but it
      looks like it mainly does it for regular reads of the target (that don't
      need FOLL_FORCE), and looking at the gdb source code seems to fall back
      on the traditional ptrace(PTRACE_POKEDATA) interface if it needs to.
      
      If this breaks something, I do have a (more complex) version that only
      enables FOLL_FORCE when somebody has PTRACE_ATTACH'ed to the target,
      like the comment here used to say ("Maybe we should limit FOLL_FORCE to
      actual ptrace users?").

        requests I had. This is all I have, and in fact this cleans out the
        RDMA subsystem's entire patchworks queue of kernel changes that are
        ready to go (well, it did for the weekend anyway, a few new patches
        are in, but they'll be coming during the -rc cycle).
      
        The first tag contains a single patch that would have conflicted if
        taken from my tree or DaveM's tree as it needed our trees merged to
        come cleanly.
      
        The second tag contains the patch series from Intel plus three other
        stragllers that came in late last week. I took them because it allowed
        me to legitimately claim that the RDMA patchworks queue was, for a
        short time, 100% cleared of all waiting kernel patches, woohoo! :-).
      
        I have it under my for-next tag, so it did get 0day and linux- next
        over the end of last week, and linux-next did show one minor conflict.

      conventions as the rest of DAX.

      dax: add tracepoints to dax_iomap_pte_fault() · a9c42b33
      Ross Zwisler authored
      Patch series "second round of tracepoints for DAX".
      
      This second round of DAX tracepoint patches adds tracing to the PTE
      fault path (dax_iomap_pte_fault(), dax_pfn_mkwrite(), dax_load_hole(),
      dax_insert_mapping()) and to the writeback path
      (dax_writeback_mapping_range(), dax_writeback_one()).
      
      The purpose of this tracing is to give us a high level view of what DAX
      is doing, whether faults are being serviced by PMDs or PTEs, and by real
      storage or by zero pages covering holes.
      
      I do have some patches nearly ready which also add tracing to
      grab_mapping_entry() and dax_insert_mapping_entry().  These are more
      targeted at logging how we are interacting with the radix tree, how we
      use empty entries for locking, whether we "downgrade" huge zero pages to
      4k PTE sized allocations, etc.  In the end it seemed to me that this
      might be too detailed to have as constantly present tracepoints, but if
      anyone sees value in having tracepoints like this in the DAX code
      permanently (Jan?), please let me know and I'll add those last two
      patches.
      
      All these tracepoints were done to be consistent with the style of the
      XFS tracepoints and with the existing DAX PMD tracepoints.
      
      This patch (of 6):
      
      Add tracepoints to dax_iomap_pte_fault(), following the same logging
      conventions as the rest of DAX.
      
      Here is an example fault that initially tries to be serviced by the PMD
      fault handler but which falls back to PTEs because the VMA isn't large
      enough to hold a PMD:

      mm: introduce memalloc_noreclaim_{save,restore} · 499118e9
      Vlastimil Babka authored
      The previous patch ("mm: prevent potential recursive reclaim due to
      clearing PF_MEMALLOC") has shown that simply setting and clearing
      PF_MEMALLOC in current->flags can result in wrongly clearing a
      pre-existing PF_MEMALLOC flag and potentially lead to recursive reclaim.
      Let's introduce helpers that support proper nesting by saving the
      previous stat of the flag, similar to the existing memalloc_noio_* and
      memalloc_nofs_* helpers.  Convert existing setting/clearing of
      PF_MEMALLOC within mm to the new helpers.
      
      There are no known issues with the converted code, but the change makes
      it more robust.

      mm: prevent potential recursive reclaim due to clearing PF_MEMALLOC · 62be1511
      Vlastimil Babka authored
      Patch series "more robust PF_MEMALLOC handling"
      
      This series aims to unify the setting and clearing of PF_MEMALLOC, which
      prevents recursive reclaim.  There are some places that clear the flag
      unconditionally from current->flags, which may result in clearing a
      pre-existing flag.  This already resulted in a bug report that Patch 1
      fixes (without the new helpers, to make backporting easier).  Patch 2
      introduces the new helpers, modelled after existing memalloc_noio_* and
      memalloc_nofs_* helpers, and converts mm core to use them.  Patches 3
      and 4 convert non-mm code.
      
      This patch (of 4):
      
      __alloc_pages_direct_compact() sets PF_MEMALLOC to prevent deadlock
      during page migration by lock_page() (see the comment in
      __unmap_and_move()).  Then it unconditionally clears the flag, which can
      clear a pre-existing PF_MEMALLOC flag and result in recursive reclaim.
      This was not a problem until commit a8161d1e ("mm, page_alloc:
      restructure direct compaction handling in slowpath"), because direct
      compation was called only after direct reclaim, which was skipped when
      PF_MEMALLOC flag was set.
      
      Even now it's only a theoretical issue, as the new callsite of
      __alloc_pages_direct_compact() is reached only for costly orders and
      when gfp_pfmemalloc_allowed() is true, which means either
      __GFP_NOMEMALLOC is in gfp_flags or in_interrupt() is true.  There is no
      such known context, but let's play it safe and make
      __alloc_pages_direct_compact() robust for cases where PF_MEMALLOC is
      already set.
      
      Fixes: a8161d1e ("mm, page_alloc: restructure direct compaction handling in slowpath")

      mm/huge_memory.c: deposit a pgtable for DAX PMD faults when required · 3b6521f5
      Oliver O'Halloran authored
      Although all architectures use a deposited page table for THP on
      anonymous VMAs, some architectures (s390 and powerpc) require the
      deposited storage even for file backed VMAs due to quirks of their MMUs.
      
      This patch adds support for depositing a table in DAX PMD fault handling
      path for archs that require it.  Other architectures should see no
      functional changes.

      Depending on the flags of the PMD being zapped there may or may not be a
      deposited pgtable to be freed.  In two of the three cases this is open
      coded while the third uses the zap_deposited_table() helper.  This patch
      converts the others to use the helper to clean things up a bit.

      time: delete CURRENT_TIME_SEC and CURRENT_TIME · bfe1c566
      Deepa Dinamani authored
      All uses of CURRENT_TIME_SEC and CURRENT_TIME macros have been replaced
      by other time functions.  These macros are also not y2038 safe.  And,
      all their use cases can be fulfilled by y2038 safe ktime_get_* variants.

      apparmorfs: replace CURRENT_TIME with current_time() · 24d0d03c
      Deepa Dinamani authored
      CURRENT_TIME macro is not y2038 safe on 32 bit systems.
      
      The patch replaces all the uses of CURRENT_TIME by current_time().
      
      This is also in preparation for the patch that transitions vfs
      timestamps to use 64 bit time and hence make them y2038 safe.
      current_time() is also planned to be transitioned to y2038 safe behavior
      along with this change.
      
      CURRENT_TIME macro will be deleted before merging the aforementioned
      change.
