       - epoll fix to make it ignore the EPOLLWAKEUP flag if the kernel has

      x86, bitops: Correct the assembly constraints to testing bitops · e0f6dec3
      H. Peter Anvin authored
      In checkin:
      
      0c44c2d0 x86: Use asm goto to implement better modify_and_test() functions
      
      the various functions which do modify and test were unified and
      optimized using "asm goto".  However, this change missed the detail
      that the bitops require an "Ir" constraint rather than an "er"
      constraint ("I" = integer constant from 0-31, "e" = signed 32-bit
      integer constant).  This would cause code to miscompile if these
      functions were used on constant bit positions 32-255 and the build to
      fail if used on constant bit positions above 255.
      
      Add the constraints as a parameter to the GEN_BINARY_RMWcc() macro to
      avoid this problem.

      NFSv4.1: Prevent a 3-way deadlock between layoutreturn, open and state recovery · f22e5edd
      Trond Myklebust authored
      Andy Adamson reports:
      
      The state manager is recovering expired state and recovery OPENs are being
      processed. If kswapd is pruning inodes at the same time, a deadlock can occur
      when kswapd calls evict_inode on an NFSv4.1 inode with a layout, and the
      resultant layoutreturn gets an error that the state mangager is to handle,
      causing the layoutreturn to wait on the (NFS client) cl_rpcwaitq.
      
      At the same time an open is waiting for the inode deletion to complete in
      __wait_on_freeing_inode.
      
      If the open is either the open called by the state manager, or an open from
      the same open owner that is holding the NFSv4 sequence id which causes the
      OPEN from the state manager to wait for the sequence id on the Seqid_waitqueue,
      then the state is deadlocked with kswapd.
      
      The fix is simply to have layoutreturn ignore all errors except NFS4ERR_DELAY.
      We already know that layouts are dropped on all server reboots, and that
      it has to be coded to deal with the "forgetful client model" that doesn't
      send layoutreturns.

      Pull ARM SoC fixes from Olof Johansson:
       "Another batch of fixes for ARM SoCs for 3.13.  The diffstat is large,
        mostly because of:
      
         - Another set of fixes to fix regressions caused by moving OMAP from
           board files to DT.  Tony thinks this was the last major set of
           fixes, with maybe just a few small patches to follow.
         - More fixes for Marvell platforms, most dealing with misdescribed
           PCIe hardware, i.e.  incorrect number of busses on some SoCs, etc.
           The line delta adds up due to various ranges moving around when
           this is fixed.
      
        But there's also:
      
         - Some smaller tweaks to defconfigs to make more boards bootable in
           my test setup for better coverage.
