      vfs: bogus warnings in fs/namei.c · 98f6ef64
      Arnd Bergmann authored
      
      
      The follow_link() function always initializes its *p argument,
      or returns an error, but when building with 'gcc -s', the compiler
      gets confused by the __always_inline attribute to the function
      and can no longer detect where the cookie was initialized.
      
      The solution is to always initialize the pointer from follow_link,
      even in the error path. When building with -O2, this has zero impact
      on generated code and adds a single instruction in the error path
      for a -Os build on ARM.
      
      Without this patch, building with gcc-4.6 through gcc-4.8 and
      CONFIG_CC_OPTIMIZE_FOR_SIZE results in:
      
      fs/namei.c: In function 'link_path_walk':
      fs/namei.c:649:24: warning: 'cookie' may be used uninitialized in this function [-Wuninitialized]

      Race scenario:

        clear_bit(Wworksched, &m->wsched);
        return;
      
      --> nobody will take care of sending the new request.
      
      This is not very likely to happen though, because p9_write_work()
      being called with an empty unsent_req_list is not frequent.
      But this also means that taking the lock earlier will not be costly.

      Pull i2c-embedded changes from Wolfram Sang:
       "The changes for i2c-embedded include:
      
         - massive rework of the omap driver
         - massive rework of the at91 driver.  In fact, the old driver gets
           removed; I am okay with this approach since the old driver was
           depending on BROKEN and its limitations made it practically
           unusable, so people used bitbanging instead.  But even if there are
           users, there is no platform_data or module parameter which would
           need to be converted.  It is just another driver doing I2C
           transfers, just way better.  Modifications of arch/arm/at91 related
           files have proper acks from the maintainer.
         - new driver for R-Car I2C
         - devicetree and generic_clock conversions and fixes
         - usual driver fixes and changes.
      
        The rework patches have come a long way and lots of people have been
        involved in creating/testing them.  Most patches have been in
        linux-next at least since 3.6-rc5.  A few have been added in the last
        week, I have to admit.
      
        An unexpected (but welcome :)) peak in private life is the cause for
        that.  The "late" patches shouldn't cause any merge conflicts and I
        will have a special eye on them during the stabilization phase.  This
        is an exception and I want to have the patches in place properly in
        time again for the next kernels."

      autofs4 - fix reset pending flag on mount fail · 49999ab2
      Ian Kent authored
      
      
      In autofs4_d_automount(), if a mount fail occurs the AUTOFS_INF_PENDING
      mount pending flag is not cleared.
      
      One effect of this is when using the "browse" option, directory entry
      attributes show up with all "?"s due to the incorrect callback and
      subsequent failure return (when in fact no callback should be made).

      gbefb: fix compile error · cd9d6f10
      Florian Tobias Schandinat authored
      
      
      The patch "drivers/video/gbefb.c: use devm_ functions" caused a
      compile error.
      
      drivers/video/gbefb.c:1159:16: error: implicit declaration of function
      'devm_ioremap' [-Werror=implicit-function-declaration]
      drivers/video/gbefb.c:1179:3: error: implicit declaration of function
      'devm_ioremap_nocache' [-Werror=implicit-function-declaration]
      
      Fix it by including linux/io.h which defines those functions.

      Merge branch 'for-3.7/core' of git://git.kernel.dk/linux-block · ce40be7a
      Linus Torvalds authored
      Pull block IO update from Jens Axboe:
       "Core block IO bits for 3.7.  Not a huge round this time, it contains:
      
         - First series from Kent cleaning up and generalizing bio allocation
           and freeing.
      
         - WRITE_SAME support from Martin.
      
         - Mikulas patches to prevent O_DIRECT crashes when someone changes
           the block size of a device.
      
         - Make bio_split() work on data-less bio's (like trim/discards).
      
         - A few other minor fixups."
      
      Fixed up silent semantic mis-merge as per Mikulas Patocka and Andrew
      Morton.  It is due to the VM no longer using a prio-tree (see commit
      6b2dbba8: "mm: replace vma prio_tree with an interval tree").
      
      So make set_blocksize() use mapping_mapped() instead of open-coding the
      internal VM knowledge that has changed.
