      arch/microblaze/include/asm/uaccess.h: Use pr_devel() instead of pr_debug() · de295cf0
      Chen Gang 提交于
      When DYNAMIC_DEBUG enabled, pr_debug() depends on KBUILD_MODNAME which
      also depends on the modules number in Makefile. The related information
      in "scripts/Makefile.lib" line 94:
      
        # $(modname_flags) #defines KBUILD_MODNAME as the name of the module it will
        # end up in (or would, if it gets compiled in)
        # Note: Files that end up in two or more modules are compiled without the
        #       KBUILD_MODNAME definition. The reason is that any made-up name would
        #       differ in different configs.
      
      For this case, 'radio-si470x-i2c.o' and 'radio-si470x-common.o' are in
      one line, so cause compiling issue. And 'uaccess.h' is a common shared
      header (not specially for drivers), so use pr_devel() instead of is OK.

      ====================
      pull request: wireless 2014-09-05
      
      Please pull this batch of fixes intended for the 3.17 stream...
      
      For the mac80211 bits, Johannes says:
      
      "Here are a few fixes for mac80211. One has been discussed for a while
      and adds a terminating NUL-byte to the alpha2 sent to userspace, which
      shouldn't be necessary but since many places treat it as a string we
      couldn't move to just sending two bytes.
      
      In addition to that, we have two VLAN fixes from Felix, a mesh fix, a
      fix for the recently introduced RX aggregation offload, a revert for
      a broken patch (that luckily didn't really cause any harm) and a small
      fix for alignment in debugfs."
      
      For the iwlwifi bits, Emmanuel says:
      
      "I revert a patch that disabled CTS to self in dvm because users
      reported issues. The revert is CCed to stable since the offending
      patch was sent to stable too. I also bump the firmware API versions
      since a new firmware is coming up. On top of that, Marcel fixes a
      bug I introduced while fixing a bug in our Kconfig file."
      
      Please let me know if there are problems!

      WANG Cong 提交于
      It is possible that the interface is already gone after joining
      the list of anycast on this interface as we don't hold a refcount
      for the device, in this case we are safe to ignore the error.
      
      What's more important, for API compatibility we should not
      change this behavior for applications even if it were correct.

      The NFS/RDMA Kconfig symbol was split into separate options for client
      and server in commit 2e8c12e1 ("xprtrdma: add separate Kconfig
      options for NFSoRDMA client and server support").
      
      Update the documentation to reflect this split.

      Documentation: i2c: rename variable "register" to "reg" · 257d6ef4
      Jose Manuel Alarcon Roldan 提交于
      The example code provided with the i2c device interface documentation
      won't compile since it uses the reserved word "register" to name a
      variable.
      
      The compiler fails with this error message:
      
       error: expected identifier or '(' before '=' token
         __u8 register = 0x20; /* Device register to access */
                       ^
      
      Rename the variable "register" to simply "reg" in the example code.
      
      Another couple of typos has been fixed as well.

           executing the appropriate method (_SUN) every time (broken in
           3.14).  From Yasuaki Ishimatsu.
      
         - Fix for a deadlock between cpuidle_lock and cpu_hotplug.lock in the

           object missing from the support for it that has been introduced
           recently.  From Mika Westerberg.
      
         - Fix for an unuseful and misleading RAPL (Running Average Power

      ufs: fix deadlocks introduced by sb mutex merge · 9ef7db7f
      Alexey Khoroshilov 提交于
      Commit 0244756e ("ufs: sb mutex merge + mutex_destroy") introduces
      deadlocks in ufs_new_inode() and ufs_free_inode().
      Most callers of that functions acqure the mutex by themselves and
      ufs_{new,free}_inode() do that via lock_ufs(),
      i.e we have an unavoidable double lock.
      
      The patch proposes to resolve the issue by making sure that
      ufs_{new,free}_inode() are not called with the mutex held.

       "The fixes all address recently discovered data corruption issues.
      
        The original Direct IO issue was discovered by Chris Mason @ Facebook
        on a production workload which mixed buffered reads with direct reads
        and writes IO to the same file.  The fix for that exposed other issues
        with page invalidation (exposed by millions of fsx operations) failing
        due to dirty buffers beyond EOF.
      
        Finally, the collapse_range code could also cause problems due to
        racing writeback changing the extent map while it was being shifted
        around.  The commits for that problem are simple mitigation fixes that
        prevent the problem from occuring.  A more robust fix for 3.18 that
        addresses the underlying problem is currently being worked on by
        Brian.
      
        Summary of fixes:
         - a direct IO read/buffered read data corruption
         - the associated fallout from the DIO data corruption fix
