      Pull powerpc fixes from Michael Ellerman:
       "Three small fixes for recently merged code:
      
         - remove a spurious WARN_ON when a PCI device has no of_node, it's
           allowed in some circumstances for there to be no of_node.
      
         - fix the offset for store EOI MMIOs in the XIVE interrupt
           controller.
      
         - fix non-const WARN_ONs which were becoming BUGs due to them losing
           BUGFLAG_WARNING in a recent cleanup patch.

       "I had thought at the time of the last pull request that there wouldn't
        be much more to go, but several things just kept trickling in over the
        last week.
      
        Instead of just the six patches to bnxt_re that I had anticipated,
        there are another five IPoIB patches, two qedr patches, and a few
        other miscellaneous patches.
      
        The bnxt_re patches are more lines of diff than I like to submit this
        late in the game. That's mostly because of the first two patches in
        the series of six. I almost dropped them just because of the lines of
        churn, but on a close review, a lot of the churn came from removing
        duplicated code sections and consolidating them into callable
        routines. I felt like this made the number of lines of change more
        acceptable, and they address problems, so I left them. The remainder
        of the patches are all small, well contained, and well understood.
      
        These have passed 0day testing, but have not been submitted to
        linux-next (but a local merge test with your current master was
        without any conflicts).
      
        Summary:
      
         - A fix for fix eea40b8f ("infiniband: call ipv6 route lookup via
           the stub interface")
      
         - Six patches against bnxt_re...the first two are considerably larger
           than I would like, but as they address real issues I went ahead and
           submitted them (it also helped that a good deal of the churn was
           removing code repeated in multiple places and consolidating it to
           one common function)
      
         - Two fixes against qedr that just came in
      
         - One fix against rxe that took a few revisions to get right plus
           time to get the proper reviews

      powerpc/debug: Add missing warn flag to WARN_ON's non-builtin path · a093c92d
      Alexey Kardashevskiy authored
      When trapped on WARN_ON(), report_bug() is expected to return
      BUG_TRAP_TYPE_WARN so the caller will increment NIP by 4 and continue.
      The __builtin_constant_p() path of the PPC's WARN_ON()
      calls (indirectly) __WARN_FLAGS() which has BUGFLAG_WARNING set,
      however the other branch does not which makes report_bug() report a
      bug rather than a warning.
      
      Fixes: f26dee15 ("debug: Avoid setting BUGFLAG_WARNING twice")

      net: don't global ICMP rate limit packets originating from loopback · 849a44de
      Jesper Dangaard Brouer authored
      Florian Weimer seems to have a glibc test-case which requires that
      loopback interfaces does not get ICMP ratelimited.  This was broken by
      commit c0303efe ("net: reduce cycles spend on ICMP replies that
      gets rate limited").
      
      An ICMP response will usually be routed back-out the same incoming
      interface.  Thus, take advantage of this and skip global ICMP
      ratelimit when the incoming device is loopback.  In the unlikely event
      that the outgoing it not loopback, due to strange routing policy
      rules, ICMP rate limiting still works via peer ratelimiting via
      icmpv4_xrlim_allow().  Thus, we should still comply with RFC1812
      (section 4.3.2.8 "Rate Limiting").
      
      This seems to fix the reproducer given by Florian.  While still
      avoiding to perform expensive and unneeded outgoing route lookup for
      rate limited packets (in the non-loopback case).

      IB/ipoib: Fix memory leak in create child syscall · 4542d66b
      Feras Daoud authored
      The flow of creating a new child goes through ipoib_vlan_add
      which allocates a new interface and checks the rtnl_lock.
      
      If the lock is taken, restart_syscall will be called to restart
      the system call again. In this case we are not releasing the
      already allocated interface, causing a leak.

      IB/ipoib: Fix access to un-initialized napi struct · 560b7c3f
      Alex Vesker authored
      There is no need to re-enable napi since we set the initialized
      flag before calling ipoib_ib_dev_stop which will disable napi,
      disabling napi twice is harmless in case it was already disabled.
      
      One more reason for this fix is that when using IPoIB new device
      driver napi is not added to priv, this can lead to kernel panic
      when rn_ops ndo_open fails.

      IB/ipoib: Delete napi in device uninit default · b53d4566
      Alex Vesker authored
      This patch mekas init_default and uninit_default symmetric
      with a call to delete napi. Additionally, the uninit_default
      gained delete napi call in case of init_default fails.
