      XZ: Fix incorrect XZ_BUF_ERROR · 9c1f8594
      Lasse Collin authored
      xz_dec_run() could incorrectly return XZ_BUF_ERROR if all of the
      following was true:
      
       - The caller knows how many bytes of output to expect and only provides
         that much output space.
      
       - When the last output bytes are decoded, the caller-provided input
         buffer ends right before the LZMA2 end of payload marker.  So LZMA2
         won't provide more output anymore, but it won't know it yet and thus
         won't return XZ_STREAM_END yet.
      
       - A BCJ filter is in use and it hasn't left any unfiltered bytes in the
         temp buffer.  This can happen with any BCJ filter, but in practice
         it's more likely with filters other than the x86 BCJ.
      
      This fixes <https://bugzilla.redhat.com/show_bug.cgi?id=735408
      
      > where
      Squashfs thinks that a valid file system is corrupt.
      
      This also fixes a similar bug in single-call mode where the uncompressed
      size of a block using BCJ + LZMA2 was 0 bytes and caller provided no
      output space.  Many empty .xz files don't contain any blocks and thus
      don't trigger this bug.
      
      This also tweaks a closely related detail: xz_dec_bcj_run() could call
      xz_dec_lzma2_run() to decode into temp buffer when it was known to be
      useless.  This was harmless although it wasted a minuscule number of CPU
      cycles.

      init: carefully handle loglevel option on kernel cmdline. · 808bf29b
      Alexander Sverdlin authored
      
      
      When a malformed loglevel value (for example "${abc}") is passed on the
      kernel cmdline, the loglevel itself is being set to 0.
      
      That then suppresses all following messages, including all the errors
      and crashes caused by other malformed cmdline options.  This could make
      debugging process quite tricky.
      
      This patch leaves the previous value of loglevel if the new value is
      incorrect and reports an error code in this case.

      teach /proc/$pid/numa_maps about transparent hugepages · 32ef4384
      Dave Hansen authored
      
      
      This is modeled after the smaps code.
      
      It detects transparent hugepages and then does a single gather_stats()
      for the page as a whole.  This has two benifits:
       1. It is more efficient since it does many pages in a single shot.
       2. It does not have to break down the huge page.

      break out numa_maps gather_pte_stats() checks · 3200a8aa
      Dave Hansen authored
      
      
      gather_pte_stats() does a number of checks on a target page
      to see whether it should even be considered for statistics.
      This breaks that code out in to a separate function so that
      we can use it in the transparent hugepage case in the next
      patch.

      make /proc/$pid/numa_maps gather_stats() take variable page size · eb4866d0
      Dave Hansen authored
      
      
      We need to teach the numa_maps code about transparent huge pages.  The
      first step is to teach gather_stats() that the pte it is dealing with
      might represent more than one page.
      
      Note that will we use this in a moment for transparent huge pages since
      they have use a single pmd_t which _acts_ as a "surrogate" for a bunch
      of smaller pte_t's.
      
      I'm a _bit_ unhappy that this interface counts in hugetlbfs page sizes
      for hugetlbfs pages and PAGE_SIZE for normal pages.  That means that to
      figure out how many _bytes_ "dirty=1" means, you must first know the
      hugetlbfs page size.  That's easier said than done especially if you
      don't have visibility in to the mount.
      
      But, that's probably a discussion for another day especially since it
      would change behavior to fix it.  But, just in case anyone wonders why
      this patch only passes a '1' in the hugetlb case...
