      Input: matrix-keymap - provide proper module license · 55220bb3
      Florian Fainelli authored
      The matrix-keymap module is currently lacking a proper module license,
      add one so we don't have this module tainting the entire kernel.  This
      issue has been present since commit 1932811f
      
       ("Input: matrix-keymap
      - uninline and prepare for device tree support")

      Pull networking fixes from David Miller:
      
       1) Netlink socket dumping had several missing verifications and checks.
      
          In particular, address comparisons in the request byte code
          interpreter could access past the end of the address in the
          inet_request_sock.
      
          Also, address family and address prefix lengths were not validated
          properly at all.
      
          This means arbitrary applications can read past the end of certain
          kernel data structures.
      
          Fixes from Neal Cardwell.
      
       2) ip_check_defrag() operates in contexts where we're in the process
          of, or about to, input the packet into the real protocols
          (specifically macvlan and AF_PACKET snooping).
      
          Unfortunately, it does a pskb_may_pull() which can modify the
          backing packet data which is not legal if the SKB is shared.  It
          very much can be shared in this context.
      
          Deal with the possibility that the SKB is segmented by using
          skb_copy_bits().
      
          Fix from Johannes Berg based upon a report by Eric Leblond.

      Revert "revert "Revert "mm: remove __GFP_NO_KSWAPD""" and associated damage · caf49191
      Linus Torvalds authored
      This reverts commits a5091539 and
      d7c3b937
      
      .
      
      This is a revert of a revert of a revert.  In addition, it reverts the
      even older i915 change to stop using the __GFP_NO_KSWAPD flag due to the
      original commits in linux-next.
      
      It turns out that the original patch really was bogus, and that the
      original revert was the correct thing to do after all.  We thought we
      had fixed the problem, and then reverted the revert, but the problem
      really is fundamental: waking up kswapd simply isn't the right thing to
      do, and direct reclaim sometimes simply _is_ the right thing to do.
      
      When certain allocations fail, we simply should try some direct reclaim,
      and if that fails, fail the allocation.  That's the right thing to do
      for THP allocations, which can easily fail, and the GPU allocations want
      to do that too.
      
      So starting kswapd is sometimes simply wrong, and removing the flag that
      said "don't start kswapd" was a mistake.  Let's hope we never revisit
      this mistake again - and certainly not this many times ;)
