       "This is the second batch of queued up rdma patches for this rc cycle.
      
        There isn't anything really major in here.  It's passed 0day,
        linux-next, and local testing across a wide variety of hardware.
        There are still a few known issues to be tracked down, but this should
        amount to the vast majority of the rdma RC fixes.
      
        Round two of 4.7 rc fixes:
      
         - A couple minor fixes to the rdma core
         - Multiple minor fixes to hfi1
         - Multiple minor fixes to mlx4/mlx4

      fix up initial thread stack pointer vs thread_info confusion · 7f1a00b6
      Linus Torvalds authored
      The INIT_TASK() initializer was similarly confused about the stack vs
      thread_info allocation that the allocators had, and that were fixed in
      commit b235beea ("Clarify naming of thread info/stack allocators").
      
      The task ->stack pointer only incidentally ends up having the same value
      as the thread_info, and in fact that will change.
      
      So fix the initial task struct initializer to point to 'init_stack'
      instead of 'init_thread_info', and make sure the ia64 definition for
      that exists.
      
      This actually makes the ia64 tsk->stack pointer be sensible for the
      initial task, but not for any other task.  As mentioned in commit
      b235beea, that whole pointer isn't actually used on ia64, since
      task_stack_page() there just points to the (single) allocation.
      
      All the other architectures seem to have copied the 'init_stack'
      definition, even if it tended to be generally unusued.

      x86: fix up a few misc stack pointer vs thread_info confusions · aca9c293
      Linus Torvalds authored
      As the actual pointer value is the same for the thread stack allocation
      and the thread_info, code that confused the two worked fine, but will
      break when the thread info is moved away from the stack allocation.  It
      also looks very confusing.
      
      For example, the kprobe code wanted to know the current top of stack.
      To do that, it used this:
      
      	(unsigned long)current_thread_info() + THREAD_SIZE
      
      which did indeed give the correct value.  But it's not only a fairly
      nonsensical expression, it's also rather complex, especially since we
      actually have this:
      
      	static inline unsigned long current_top_of_stack(void)
      
      which not only gives us the value we are interested in, but happens to
      be how "current_thread_info()" is currently defined as:
      
      	(struct thread_info *)(current_top_of_stack() - THREAD_SIZE);
      
      so using current_thread_info() to figure out the top of the stack really
      is a very round-about thing to do.
      
      The other cases are just simpler confusion about task_thread_info() vs
      task_stack_page(), which currently return the same pointer - but if you
      want the stack page, you really should be using the latter one.
      
      And there was one entirely unused assignment of the current stack to a
      thread_info pointer.
      
      All cleaned up to make more sense today, and make it easier to move the
      thread_info away from the stack in the future.
      
      No semantic changes.

      Clarify naming of thread info/stack allocators · b235beea
      Linus Torvalds authored
      We've had the thread info allocated together with the thread stack for
      most architectures for a long time (since the thread_info was split off
      from the task struct), but that is about to change.
      
      But the patches that move the thread info to be off-stack (and a part of
      the task struct instead) made it clear how confused the allocator and
      freeing functions are.
      
      Because the common case was that we share an allocation with the thread
      stack and the thread_info, the two pointers were identical.  That
      identity then meant that we would have things like
      
      	ti = alloc_thread_info_node(tsk, node);
      	...
      	tsk->stack = ti;
      
      which certainly _worked_ (since stack and thread_info have the same
      value), but is rather confusing: why are we assigning a thread_info to
      the stack? And if we move the thread_info away, the "confusing" code
      just gets to be entirely bogus.
      
      So remove all this confusion, and make it clear that we are doing the
      stack allocation by renaming and clarifying the function names to be
      about the stack.  The fact that the thread_info then shares the
      allocation is an implementation detail, and not really about the
      allocation itself.
      
      This is a pure renaming and type fix: we pass in the same pointer, it's
      just that we clarify what the pointer means.
      
      The ia64 code that actually only has one single allocation (for all of
      task_struct, thread_info and kernel thread stack) now looks a bit odd,
      but since "tsk->stack" is actually not even used there, that oddity
      doesn't matter.  It would be a separate thing to clean that up, I
      intentionally left the ia64 changes as a pure brute-force renaming and
      type change.

      nfsd: check permissions when setting ACLs · 99965378
      Ben Hutchings authored
      Use set_posix_acl, which includes proper permission checks, instead of
      calling ->set_acl directly.  Without this anyone may be able to grant
      themselves permissions to a file by setting the ACL.
      
      Lock the inode to make the new checks atomic with respect to set_acl.
      (Also, nfsd was the only caller of set_acl not locking the inode, so I
      suspect this may fix other races.)
      
      This also simplifies the code, and ensures our ACLs are checked by
      posix_acl_valid.
      
      The permission checks and the inode locking were lost with commit
      4ac7249e, which changed nfsd to use the set_acl inode operation directly
      instead of going through xattr handlers.

      xen-pciback: return proper values during BAR sizing · d2bd05d8
      Jan Beulich authored
      Reads following writes with all address bits set to 1 should return all
      changeable address bits as one, not the BAR size (nor, as was the case
      for the upper half of 64-bit BARs, the high half of the region's end
      address). Presumably this didn't cause any problems so far because
      consumers use the value to calculate the size (usually via val & -val),
      and do nothing else with it.
      
      But also consider the exception here: Unimplemented BARs should always
      return all zeroes.
      
      And finally, the check for whether to return the sizing address on read
      for the ROM BAR should ignore all non-address bits, not just the ROM
      Enable one.

      Pull PCI fix from Bjorn Helgaas:
       "Here's a small fix for v4.7.  This problem was actually introduced in
        v4.6 when we unified Kconfig, making PCIe support available everywhere
        including sparc, where config reads into unaligned buffers cause
        warnings.  This fix is from Dave Miller.
      
        As a reminder, any future PCI fixes for v4.7 will probably come from
        Alex Williamson, since I'll be on vacation for most of the rest of
        this cycle.  I should be back about the time the merge window opens"

      A bit bigger than I would normally like, but most of the large changes are
      for polaris support and since polaris went upstream in 4.7, I'd like
      to get the fixes in so it's in good shape when the hw becomes available.
      The major changes only touch the polaris code so there is little chance
      for regressions on other asics.  The rest are just the usual collection
      of bug fixes.

      Since HW trigger mode was suppoted we have faced with a issue
      that Display panel didn't work correctly when trigger mode was changed
      in booting time.
      For this, we keep trigger mode with SW trigger mode in default mode
      like we did before.
      
      However, we will need to consider PSR(Panel Self Reflash) mode to resolve
      this issue fundamentally later.
