      ioat: cleanup ->timer_fn() and ->cleanup_fn() prototypes · aa4d72ae
      Dan Williams authored
      If the calling convention of ->timer_fn() and ->cleanup_fn() are unified
      across hardware versions we can drop parameters to ioat_init_channel() and
      unify ioat_is_dma_complete() implementations.
      
      Both ->timer_fn() and ->cleanup_fn() are modified to expect a struct
      dma_chan pointer.

      ioat3: interrupt coalescing · b9cc9869
      Dan Williams authored
      The hardware automatically disables further interrupts after each event
      until rearmed.  This allows a delay to be injected between the occurence
      of the interrupt and the running of the cleanup routine.  The delay is
      scaled by the descriptor backlog and then written to the INTRDELAY
      register which specifies the number of microseconds to hold off
      interrupt delivery after an interrupt event occurs.  According to
      powertop this reduces the interrupt rate from ~5000 intr/s to ~150
      intr/s per without affecting throughput (simple dd to a raid6 array).

      ioat: close potential BUG_ON race in the descriptor cleanup path · aa75db00
      Dan Williams authored
      Since ioat_cleanup_preamble() and the update of the last completed
      descriptor are not synchronized there is a chance that two cleanup threads
      can see descriptors to clean.  If the first cleans up all pending
      descriptors then the second will trigger the BUG_ON.

      Prioritize synchronous signals over 'normal' signals · a27341cd
      Linus Torvalds authored
      This makes sure that we pick the synchronous signals caused by a
      processor fault over any pending regular asynchronous signals sent to
      use by [t]kill().
      
      This is not strictly required semantics, but it makes it _much_ easier
      for programs like Wine that expect to find the fault information in the
      signal stack.
      
      Without this, if a non-synchronous signal gets picked first, the delayed
      asynchronous signal will have its signal context pointing to the new
      signal invocation, rather than the instruction that caused the SIGSEGV
      or SIGBUS in the first place.
      
      This is not all that pretty, and we're discussing making the synchronous
      signals more explicit rather than have these kinds of implicit
      preferences of SIGSEGV and friends.  See for example
      
      	http://bugzilla.kernel.org/show_bug.cgi?id=15395
      
      for some of the discussion.  But in the meantime this is a simple and
      fairly straightforward work-around, and the whole
      
      	if (x & Y)
      		x &= Y;
      
      thing can be compiled into (and gcc does do it) just three instructions:
      
      	movq    %rdx, %rax
      	andl    $Y, %eax
      	cmovne  %rax, %rdx
      
      so it is at least a simple solution to a subtle issue.
