      Pull pin control fixes from Linus Walleij:
 "These are the pin control fixes I have gathered since the return from
  my vacation. They boiled in -next a while so let's get them in.

  Apart from the documentation build it is purely driver fixes. Which is
  nice. The Intel fixes seem kind of important.

   - Fix the documentation build as the docs were moved

   - Correct the UART pin list on the Intel Merrifield

   - Fix pin assignment and number of pins on the Marvell Armada 37xx
     pin controller

   - Cover the Setzer models in the Chromebook DMI quirk in the Intel
     cheryview driver so they start working

   - Add the missing "sim" function to the sunxi driver

   - Fix USB pin definitions on Uniphier Pro4

   - Smatch fix for invalid reference in the zx pin control driver"

      futex: Remove unnecessary warning from get_futex_key · 48fb6f4d
      Mel Gorman authored 
      Commit 65d8fc77 ("futex: Remove requirement for lock_page() in
get_futex_key()") removed an unnecessary lock_page() with the
side-effect that page->mapping needed to be treated very carefully.

Two defensive warnings were added in case any assumption was missed and
the first warning assumed a correct application would not alter a
mapping backing a futex key.  Since merging, it has not triggered for
any unexpected case but Mark Rutland reported the following bug
triggering due to the first warning.

  kernel BUG at kernel/futex.c:679!
  Internal error: Oops - BUG: 0 [#1] PREEMPT SMP
  Modules linked in:
  CPU: 0 PID: 3695 Comm: syz-executor1 Not tainted 4.13.0-rc3-00020-g307fec773ba3 #3

  pc : [<ffff00000821ac14>] lr : [<ffff00000821ac14>] pstate: 80000145

The fact that it's a bug instead of a warning was due to an unrelated
arm64 problem, but the warning itself triggered because the underlying
mapping changed.

This is an application issue but from a kernel perspective it's a
recoverable situation and the warning is unnecessary so this patch
removes the warning.  The warning may potentially be triggered with the
following test program from Mark although it may be necessary to adjust
NR_FUTEX_THREADS to be a value smaller than the number of CPUs in the
system.

      net: avoid skb_warn_bad_offload false positives on UFO · 8d63bee6
      Willem de Bruijn authored 
      skb_warn_bad_offload triggers a warning when an skb enters the GSO
stack at __skb_gso_segment that does not have CHECKSUM_PARTIAL
checksum offload set.

Commit b2504a5d ("net: reduce skb_warn_bad_offload() noise")
observed that SKB_GSO_DODGY producers can trigger the check and
that passing those packets through the GSO handlers will fix it
up. But, the software UFO handler will set ip_summed to
CHECKSUM_NONE.

When __skb_gso_segment is called from the receive path, this
triggers the warning again.

Make UFO set CHECKSUM_UNNECESSARY instead of CHECKSUM_NONE. On
Tx these two are equivalent. On Rx, this better matches the
skb state (checksum computed), as CHECKSUM_NONE here means no
checksum computed.

      ppp: fix xmit recursion detection on ppp channels · 0a0e1a85
      Guillaume Nault authored 
      Commit e5dadc65 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.

This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.

Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

      Håkon Bugge authored 
      In commit 7e3f2952 ("rds: don't let RDS shutdown a connection
while senders are present"), refilling the receive queue was removed
from rds_ib_recv(), along with the increment of
s_ib_rx_refill_from_thread.

Commit 73ce4317 ("RDS: make sure we post recv buffers")
re-introduces filling the receive queue from rds_ib_recv(), but does
not add the statistics counter. rds_ib_recv() was later renamed to
rds_ib_recv_path().

This commit reintroduces the statistics counting of
s_ib_rx_refill_from_thread and s_ib_rx_refill_from_cq.

      net: sched: set xt_tgchk_param par.net properly in ipt_init_target · ec0acb09
      Xin Long authored 
      Now xt_tgchk_param par in ipt_init_target is a local varibale,
par.net is not initialized there. Later when xt_check_target
calls target's checkentry in which it may access par.net, it
would cause kernel panic.

Jaroslav found this panic when running:

  # ip link add TestIface type dummy
  # tc qd add dev TestIface ingress handle ffff:
  # tc filter add dev TestIface parent ffff: u32 match u32 0 0 \
    action xt -j CONNMARK --set-mark 4

This patch is to pass net param into ipt_init_target and set
par.net with it properly in there.

v1->v2:
  As Wang Cong pointed, I missed ipt_net_id != xt_net_id, so fix
  it by also passing net_id to __tcf_ipt_init.
v2->v3:
  Missed the fixes tag, so add it.

      parse-maintainers: Move matching sections from MAINTAINERS · b95c29a2
      Joe Perches authored 
      Allow any number of command line arguments to match either the
section header or the section contents and create new files.

Create MAINTAINERS.new and SECTION.new.

This allows scripting of the movement of various sections from
MAINTAINERS.

      parse-maintainers: Use perl hash references and specific filenames · fe909030
      Joe Perches authored 
      Instead of reading STDIN and writing STDOUT, use specific filenames of
MAINTAINERS and MAINTAINERS.new.

Use hash references instead of global hash %hash so future modifications
can read and write specific hashes to split up MAINTAINERS into multiple
files using a script.

      parse-maintainers: Add section pattern sorting · 61f74164
      Joe Perches authored 
      Section [A-Z]: patterns are not currently in any required sorting order.
Add a specific sorting sequence to MAINTAINERS entries.
Sort F: and X: patterns in alphabetic order.

The preferred section ordering is:

  SECTION HEADER
  M:	Maintainers
  R:	Reviewers
  P:	Named persons without email addresses
  L:	Mailing list addresses
  S:	Status of this section (Supported, Maintained, Orphan, etc...)
  W:	Any relevant URLs
  T:	Source code control type (git, quilt, etc)
  Q:	Patchwork patch acceptance queue site
  B:	Bug tracking URIs
  C:	Chat URIs
  F:	Files with wildcard patterns (alphabetic ordered)
  X:	Excluded files with wildcard patterns (alphabetic ordered)
  N:	Files with regex patterns
  K:	Keyword regexes in source code for maintainership identification

Miscellaneous perl neatening:

 - Rename %map to %hash, map has a different meaning in perl
 - Avoid using \& and local variables for function indirection
 - Use return for a little c like clarity
 - Use c-like function call style instead of &function

      get_maintainer: Prepare for separate MAINTAINERS files · 6f7d98ec
      Joe Perches authored 
      Allow for MAINTAINERS to become a directory and if it is,
read all the files in the directory for maintained sections.

Optionally look for all files named MAINTAINERS in directories
excluding the .git directory by using --find-maintainer-files.

This optional feature adds ~.3 seconds of CPU on an Intel
i5-6200 with an SSD.

Miscellanea:

 - Create a read_maintainer_file subroutine from the existing code
 - Test only the existence of MAINTAINERS, not whether it's a file

      random: fix warning message on ia64 and parisc · 51d96dc2
      Helge Deller authored 
      Fix the warning message on the parisc and IA64 architectures to show the
correct function name of the caller by using %pS instead of %pF. The
message is printed with the value of _RET_IP_ which calls
__builtin_return_address(0) and as such returns the IP address caller
instead of pointer to a function descriptor of the caller.

The effect of this patch is visible on the parisc and ia64 architectures
only since those are the ones which use function descriptors while on
all others %pS and %pF will behave the same.
