      Pull namespace bugfixes from Eric Biederman:
       "This tree includes a partial revert for "fs: Limit sys_mount to only
        request filesystem modules." When I added the new style module aliases
        to the filesystems I deleted the old ones.  A bad move.  It turns out
        that distributions like Arch linux use module aliases when
        constructing ramdisks.  Which meant ultimately that an ext3 filesystem
        mounted with ext4 would not result in the ext4 module being put into
        the ramdisk.
      
        The other change in this tree adds a handful of filesystem module
        alias I simply failed to add the first time.  Which inconvinienced a
        few folks using cifs.
      
        I don't want to inconvinience folks any longer than I have to so here
        are these trivial fixes."

      idr: idr_alloc() shouldn't trigger lowmem warning when preloaded · 59bfbcf0

      GFP_NOIO is often used for idr_alloc() inside preloaded section as the
      allocation mask doesn't really matter.  If the idr tree needs to be
      expanded, idr_alloc() first tries to allocate using the specified
      allocation mask and if it fails falls back to the preloaded buffer.  This
      order prevent non-preloading idr_alloc() users from taking advantage of
      preloading ones by using preload buffer without filling it shifting the
      burden of allocation to the preload users.
      
      Unfortunately, this allowed/expected-to-fail kmem_cache allocation ends up
      generating spurious slab lowmem warning before succeeding the request from
      the preload buffer.
      
      This patch makes idr_layer_alloc() add __GFP_NOWARN to the first
      kmem_cache attempt and try kmem_cache again w/o __GFP_NOWARN after
      allocation from preload_buffer fails so that lowmem warning is generated
      if not suppressed by the original @gfp_mask.

      UAPI: fix endianness conditionals in M32R's asm/stat.h · 415586c9
      David Howells authored
      
      
      In the UAPI header files, __BIG_ENDIAN and __LITTLE_ENDIAN must be
      compared against __BYTE_ORDER in preprocessor conditionals where these are
      exposed to userspace (that is they're not inside __KERNEL__ conditionals).
      
      However, in the main kernel the norm is to check for
      "defined(__XXX_ENDIAN)" rather than comparing against __BYTE_ORDER and
      this has incorrectly leaked into the userspace headers.
      
      The definition of struct stat64 in M32R's asm/stat.h is wrong in this way.
       Note that userspace will likely interpret the field order incorrectly as
      the big-endian variant on little-endian machines - depending on header
      inclusion order.
      
      [!!!] NOTE [!!!]  This patch may adversely change the userspace API.  It might
      be better to fix the ordering of st_blocks and __pad4 in struct stat64.

       ("decompressors: make the default XZ_DEC_* config
      match the selected architecture") added
      
      	default y if POWERPC
      
      to lib/xz/Kconfig.  But there is no Kconfig symbol POWERPC.  The most
      general Kconfig symbol for the powerpc architecture is PPC.  So let's
      use that.

      If find_vma() fails, sys_remap_file_pages() will dereference `vma', which
      contains NULL.  Fix it by checking the pointer.
      
      (We could alternatively check for err==0, but this seems more direct)
      
      (The vm_flags change is to squish a bogus used-uninitialised warning
      without adding extra code).
