      include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
      
      percpu.h is included by sched.h and module.h and thus ends up being
      included when building most .c files.  percpu.h includes slab.h which
      in turn includes gfp.h making everything defined by the two files
      universally available and complicating inclusion dependencies.
      
      percpu.h -> slab.h dependency is about to be removed.  Prepare for
      this change by updating users of gfp and slab facilities include those
      headers directly instead of assuming availability.  As this conversion
      needs to touch large number of source files, the following script is
      used as the basis of conversion.
      
        http://userweb.kernel.org/~tj/misc/slabh-sweep.py
      
      The script does the followings.
      
      * Scan files for gfp and slab usages and update includes such that
        only the necessary includes are there.  ie. if only gfp is used,
        gfp.h, if slab is used, slab.h.
      
      * When the script inserts a new include, it looks at the include
        blocks and try to put the new include such that its order conforms
        to its surrounding.  It's put in the include block which contains
        core kernel includes, in the same order that the rest are ordered -
        alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
        doesn't seem to be any matching order.
      
      * If the script can't find a place to put a new include (mostly
        because the file doesn't have fitting include block), it prints out
        an error message indicating which .h file needs to be added to the
        file.
      
      The conversion was done in the following steps.
      
      1. The initial automatic conversion of all .c files updated slightly
         over 4000 files, deleting around 700 includes and adding ~480 gfp.h
         and ~3000 slab.h inclusions.  The script emitted errors for ~400
         files.
      
      2. Each error was manually checked.  Some didn't need the inclusion,
         some needed manual addition while adding it to implementation .h or
         embedding .c file was more appropriate for others.  This step added
         inclusions to around 150 files.
      
      3. The script was run again and the output was compared to the edits
         from #2 to make sure no file was left behind.
      
      4. Several build tests were done and a couple of problems were fixed.
         e.g. lib/decompress_*.c used malloc/free() wrappers around slab
         APIs requiring slab.h to be added manually.
      
      5. The script was run on all .h files but without automatically
         editing them as sprinkling gfp.h and slab.h inclusions around .h
         files could easily lead to inclusion dependency hell.  Most gfp.h
         inclusion directives were ignored as stuff from gfp.h was usually
         wildly available and often used in preprocessor macros.  Each
         slab.h inclusion directive was examined and added manually as
         necessary.
      
      6. percpu.h was updated not to include slab.h.
      
      7. Build test were done on the following configurations and failures
         were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
         distributed build env didn't work with gcov compiles) and a few
         more options had to be turned off depending on archs to make things
         build (like ipr on powerpc/64 which failed due to missing writeq).
      
         * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
         * powerpc and powerpc64 SMP allmodconfig
         * sparc and sparc64 SMP allmodconfig
         * ia64 SMP allmodconfig
         * s390 SMP allmodconfig
         * alpha SMP allmodconfig
         * um on x86_64 SMP allmodconfig
      
      8. percpu.h modifications were reverted so that it could be applied as
         a separate patch and serve as bisection point.
      
      Given the fact that I had only a couple of failures from tests on step
      6, I'm fairly confident about the coverage of this conversion patch.
      If there is a breakage, it's likely to be something in one of the arch
      headers which should be easily discoverable easily on most builds of
      the specific arch.

      ASoC: Register platform DAIs · 3f4b783c
      Mark Brown 提交于
      Register all platform DAIs with the core.  In line with current behaviour
      this is done at module probe time rather than when the devices are probed
      (since currently that only happens as the entire ASoC card is registered
      except for those drivers that currently implement some kind of hotplug).
      Since the core currently ignores DAI registration this has no practical
      effect.

      ASoC: Merge snd_soc_ops into snd_soc_dai_ops · dee89c4d
      Mark Brown 提交于
      Liam Girdwood's ASoC v2 work avoids having two different ops structures
      for DAIs by merging the members of struct snd_soc_ops into struct
      snd_soc_dai_ops, allowing per DAI configuration for everything.
      Backport this change.
      
      This paves the way for future work allowing any combination of DAIs to
      be connected rather than having fixed purpose CODEC and CPU DAIs and
      only allowing CODEC<->CPU interconnections.

      ALSA: asoc: restrict sample rate and size in Freescale MPC8610 sound drivers · be41e941
      Timur Tabi 提交于
      The Freescale MPC8610 SSI device has the option of using one clock for both
      transmit and receive (synchronous mode), or independent clocks (asynchronous).
      The SSI driver, however, programs the SSI into synchronous mode and then
      tries to program the clock registers independently.  The result is that the wrong
      sample size is usually generated during recording.
      
      This patch fixes the discrepancy by restricting the sample rate and sample size
      of the playback and capture streams.  The SSI driver remembers which stream
      is opened first.  When a second stream is opened, that stream is constrained
      to the same sample rate and size as the first stream.
      
      A future version of this driver will lift the sample size restriction.
      Supporting independent sample rates is more difficult, because only certain
      codecs provide dual independent clocks.
