      Pull more power management and ACPI updates from Rafael Wysocki:
      
       - Fix for a recent cpufreq regression that caused WARN() to trigger
         overzealously in a couple of places and spam the kernel log with
         useless garbage as a result.  From Viresh Kumar.
      
       - ACPI dock fix removing a discrepancy between the definition of
         acpi_dock_init(), which says that the function returns int, and its
         header in the header file, which says that it is a void function.
         The function is now defined as void too.
      
       - ACPI PM fix for failures to update device power states as needed, for
         example, during resume from system suspend, because the old state was
         deeper than the new one, but the new one is not D0.
      
       - Fix for two debug messages in the ACPI power resources code that
         don't have a newline at the end and make the kernel log difficult to
         read.  From Mika Westerberg.
      
       - Two ACPI cleanups from Naresh Bhat and Haicheng Li.
      
       - cpupower updates from Thomas Renninger, including Intel Haswell
         support improvements and a new idle-set subcommand among other

      Pull tracing changes from Steven Rostedt:
       "The majority of the changes here are cleanups for the large changes
        that were added to 3.10, which includes several bug fixes that have
        been marked for stable.
      
        As for new features, there were a few, but nothing to write to LWN
        about.  These include:
      
        New function trigger called "dump" and "cpudump" that will cause
        ftrace to dump its buffer to the console when the function is called.
        The difference between "dump" and "cpudump" is that "dump" will dump
        the entire contents of the ftrace buffer, where as "cpudump" will only
        dump the contents of the ftrace buffer for the CPU that called the
        function.
      
        Another small enhancement is a new sysctl switch called
        "traceoff_on_warning" which, when enabled, will disable tracing if any
        WARN_ON() is triggered.  This is useful if you want to debug what
        caused a warning and do not want to risk losing your trace data by the
        ring buffer overwriting the data before you can disable it.  There's
        also a kernel command line option that will make this enabled at boot

      Linus Torvalds 提交于
      This reverts commit d2aae847.
      
      It is completely and utterly broken.  Module install should not build
      any files, and adding broken dependencies to "help" it build files is
      complete and utter sh*t.
      
      The kernel should not be built by root, and "make install" and "make
      module_install" (that for obvious reasons need to be run as root)
      absolutely must not build any files.  They should only ever copy the
      already-built files over.
      
      So having dependencies for the install targets is wrong, wrong, wrong.
      
      If you try to install a kernel without building it first, you *should*
      get errors. The build system shouldn't try to help root build the files.

      zswap: add to mm/ · 2b281117
      Seth Jennings 提交于
      zswap is a thin backend for frontswap that takes pages that are in the
      process of being swapped out and attempts to compress them and store
      them in a RAM-based memory pool.  This can result in a significant I/O
      reduction on the swap device and, in the case where decompressing from
      RAM is faster than reading from the swap device, can also improve
      workload performance.
      
      It also has support for evicting swap pages that are currently
      compressed in zswap to the swap device on an LRU(ish) basis.  This
      functionality makes zswap a true cache in that, once the cache is full,
      the oldest pages can be moved out of zswap to the swap device so newer
      pages can be compressed and stored in zswap.
      
      This patch adds the zswap driver to mm/

      zbud: add to mm/ · 4e2e2770
      Seth Jennings 提交于
      zbud is an special purpose allocator for storing compressed pages.  It
      is designed to store up to two compressed pages per physical page.
      While this design limits storage density, it has simple and
      deterministic reclaim properties that make it preferable to a higher
      density approach when reclaim will be used.
      
      zbud works by storing compressed pages, or "zpages", together in pairs
      in a single memory page called a "zbud page".  The first buddy is "left
      justifed" at the beginning of the zbud page, and the last buddy is
      "right justified" at the end of the zbud page.  The benefit is that if
      either buddy is freed, the freed buddy space, coalesced with whatever
      slack space that existed between the buddies, results in the largest
      possible free region within the zbud page.
      
      zbud also provides an attractive lower bound on density.  The ratio of
      zpages to zbud pages can not be less than 1.  This ensures that zbud can
      never "do harm" by using more pages to store zpages than the
      uncompressed zpages would have used on their own.
      
      This implementation is a rewrite of the zbud allocator internally used
      by zcache in the driver/staging tree.  The rewrite was necessary to
      remove some of the zcache specific elements that were ingrained
      throughout and provide a generic allocation interface that can later be
      used by zsmalloc and others.
      
      This patch adds zbud to mm/ for later use by zswap.

      By calling rpcauth_create() while holding the sn->pipefs_sb_lock, we
      end up deadlocking in gss_pipes_dentries_create_net().
      Fix is to register the client and release the mutex before calling
      rpcauth_create().
