       "The two highlights are a set of improvements to how rbd read-only
        mappings are handled and a conversion to the new mount API (slightly
        complicated by the fact that we had a common option parsing framework
        that called out into rbd and the filesystem instead of them calling
        into it).
      
        Also included a few scattered fixes and a MAINTAINERS update for rbd,
        adding Dongsheng as a reviewer"

       "Summary of modules changes for the 5.5 merge window:
      
         - Refactor include/linux/export.h and remove code duplication between

      mm: remove __ARCH_HAS_4LEVEL_HACK and include/asm-generic/4level-fixup.h · f949286c
      Mike Rapoport authored
      There are no architectures that use include/asm-generic/4level-fixup.h
      therefore it can be removed along with __ARCH_HAS_4LEVEL_HACK define.

      um: add support for folded p4d page tables · e19f97ed
      Mike Rapoport authored
      The UML port uses 4 and 5 level fixups to support higher level page
      table directories in the generic VM code.
      
      Implement primitives necessary for the 4th level folding, add walks of
      p4d level where appropriate and drop usage of __ARCH_USE_5LEVEL_HACK.

      alpha: use pgtable-nopud instead of 4level-fixup · a73c9489
      Mike Rapoport authored
      Patch series "mm: remove __ARCH_HAS_4LEVEL_HACK", v13.
      
      These patches convert several architectures to use page table folding
      and remove __ARCH_HAS_4LEVEL_HACK along with
      include/asm-generic/4level-fixup.h.
      
      For the nommu configurations the folding is already implemented by the
      generic code so the only change was to use the appropriate header file.
      
      As for the rest, the changes are mostly about mechanical replacement of
      pgd accessors with pud/pmd ones and the addition of higher levels to
      page table traversals.
      
      With Vineet's patches from "elide extraneous generated code for folded
      p4d/pud/pmd" series [1] there is a small shrink of the kernel size of
      about -0.01% for the defconfig builds.
      
      This patch (of 13):
      
      It is not likely alpha will have 5-level page tables.
      
      Replace usage of include/asm-generic/4level-fixup.h and implied
      __ARCH_HAS_4LEVEL_HACK with include/asm-generic/pgtable-nopud.h and
      adjust page table manipulation macros and functions accordingly.

      lib/test_bitmap: force argument of bitmap_parselist_user() to proper address space · 17b6753f
      Andy Shevchenko authored
      Patch series "gpio: pca953x: Convert to bitmap (extended) API", v2.
      
      While converting gpio-pca953x driver to bitmap API, I noticed that we
      have no function to replace bits.
      
      So, that's how patch 7 appears.
      
      First 6 patches are preparatory of the test suite (including some
      warning fixes, etc).
      
      Patches 8-9 are preparatory for the GPIO driver to be easier converted
      to bitmap API, conversion to which happens in patch 10.
      
      Patch 11 contains simple indentation fixes.
      
      This patch (of 11):
      
      Sparse complains:
      
        lib/test_bitmap.c:345:58: warning: incorrect type in argument 1 (different address spaces)
        lib/test_bitmap.c:345:58:    expected char const [noderef] <asn:1> *ubuf
        lib/test_bitmap.c:345:58:    got char const *const in
      
      Force argument of bitmap_parselist_user() to proper address space.

      It is just a matter of missing include directive.
      
      Include <asm/ipcbuf.h> to make it self-contained, and add it to
      the compile-test coverage.
