      Kbuild: use normal compression settings for tar*-pkg · b589c8ae
      Andi Kleen authored
      For large kernel configurations (like a distribution kernel)
      targz-pkg takes a quite long time to just do the compression.
      I clocked it at 15+mins for a SUSE kernel like config on a fast
      system.  And tarxz and bzip2 are even slower.
      
      The main reason is that the script that is doing the taring sets
      the highest compression level (-9).  When I change it to just
      use the defaults the gzip time for the same kernel goes down
      to ~3 mins. I haven't tested xz and bzip, but I expect those
      to be much faster too.
      
      I'm not willing to wait that long for a small compression
      gain. So just change the script to use the defaults.

           implementations.
         - conversion of amba-pl08x.c to use these helper functions.
         - addition of OMAP DMA engine driver (using these helper functions),
           and conversion of some of the OMAP DMA users to use DMA engine.
      
        Nothing in the helper functions is ARM specific, so I hope that other
        implementations can consolidate some of their code by making use of
        these helpers.
      
        This has been sitting in linux-next most of the merge cycle, and has
        been tested by several OMAP folk.  I've tested it on sa11x0 platforms,
        and given it my best shot on my broken platforms which have the
        amba-pl08x controller.
      
        The last point is the addition to feature-removal-schedule.txt, which
        will have a merge conflict.  Between myself and TI, we're planning to
        remove the old TI DMA implementation next year."

      md/raid1: submit IO from originating thread instead of md thread. · f54a9d0e
      NeilBrown authored
      queuing writes to the md thread means that all requests go through the
      one processor which may not be able to keep up with very high request
      rates.
      
      So use the plugging infrastructure to submit all requests on unplug.
      If a 'schedule' is needed, we fall back on the old approach of handing
      the requests to the thread for it to handle.

      raid5: make_request use batch stripe release · 8811b596
      Shaohua Li authored
      make_request() does stripe release for every stripe and the stripe usually has
      count 1, which makes previous release_stripe() optimization not work. In my
      test, this release_stripe() becomes the heaviest pleace to take
      conf->device_lock after previous patches applied.
      
      Below patch makes stripe release batch. All the stripes will be released in
      unplug. The STRIPE_ON_UNPLUG_LIST bit is to protect concurrent access stripe
      lru.
