ad040d8df6 i.MX fixes for 4.10:
- A format fix for vf610-zii-dev-rev-b.dts, which has a very odd line
    due to misses a newline.
  - A fix to imx-weim bus error seen on board which doesn't actually use
    the bus.
  - A fix for imx6qdl-nitrogen6x board which has conflicting usage of
    pad NANDF_CS2.
  - A cleanup on i.MX1 machine to remove .map_io callback, which also
    fixes a compiling error for NOMMU build.
  - Fix AVIC base address in i.MX31 device tree source.  The problem was
    shadowed by the AVIC driver, which takes the correct base address
    from a SoC specific header file.

46a3bf8071 Fist set of fixes for omaps for v4.10-rc cycle, mostly
to deal with various regressions noticed during the merge
 window and to fix various device tree configurations for
 boards. Also included is removal of mach-omap2/gpio.c that
 is now dead code with device tree based booting that should
 be OK for the early -rc cycle:
 
 - A series of fixes to add empty chosen node to fix regressions
   caused for bootloaders that don't create chosen node as the
   decompressor needs the chosen node to merge command line and
   ATAGs into it
 
 - Fix missing logicpd-som-lv-37xx-devkit.dtb entry in Makefile
 
 - Fix regression for am437x timers
 
 - Fix wrong strcat for non-NULL terminated string
 
 - A series of changes to fix tps65217 interrupts to not use
   defines as we don't do that for interrupts
 
 - Two patches to fix USB VBUS detection on am57xx-idk and force it
   to peripheral mode until dwc3 role detection is working
 
 - Add missing dra72-evm-tps65917 missing voltage supplies
   accidentally left out of an earlier patch
 
 - Fix n900 eMMC detection when booted on qemu
 
 - Remove unwanted pr_err on failed memory allocation for
   prm_common.c
 
 - Remove legacy mach-omap2/gpio.c that now is dead code
   since we boot mach-omap2 in device tree only mode

116dad7d43 ARM: dts: imx6: Disable "weim" node in the dtsi files
Commit 1be81ea5860744520 ("ARM: dts: imx6: Add imx-weim parameters to
dtsi's") causes the following probe error when the weim node is not
present on the board dts (such as imx6q-sabresd):

imx-weim 21b8000.weim: Invalid 'ranges' configuration
imx-weim: probe of 21b8000.weim failed with error -22

There is no need to always enable the "weim" node on mx6. Do the same
as in the other i.MX dtsi files where "weim" is disabled and only gets
enabled on a per dts basis.

All the imx6 weim dts users explicitily provide 'status = "okay"', so
this change has no impact on current imx6 weim users.

If a board does not use the weim driver it will not describe its 'ranges'
property, so simply disable the 'weim' node in the imx6 dtsi files to
avoid such probe error message.

There is no need to define map_io only for debug_ll_io_init() since it
is already called in devicemaps_init() if map_io is NULL.

Apart from that, for NOMMU build debug_ll_io_init() is a nop which
leads to following error:

4759d386d5 Merge branch 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm
Pull DAX updates from Dan Williams:
 "The completion of Jan's DAX work for 4.10.

  As I mentioned in the libnvdimm-for-4.10 pull request, these are some
  final fixes for the DAX dirty-cacheline-tracking invalidation work
  that was merged through the -mm, ext4, and xfs trees in -rc1. These
  patches were prepared prior to the merge window, but we waited for
  4.10-rc1 to have a stable merge base after all the prerequisites were
  merged.

  Quoting Jan on the overall changes in these patches:

     "So I'd like all these 6 patches to go for rc2. The first three
      patches fix invalidation of exceptional DAX entries (a bug which
      is there for a long time) - without these patches data loss can
      occur on power failure even though user called fsync(2). The other
      three patches change locking of DAX faults so that ->iomap_begin()

Linus Torvalds
b91e1302ad mm: optimize PageWaiters bit use for unlock_page()
In commit 62906027091f ("mm: add PageWaiters indicating tasks are
waiting for a page bit") Nick Piggin made our page locking no longer
unconditionally touch the hashed page waitqueue, which not only helps
performance in general, but is particularly helpful on NUMA machines
where the hashed wait queues can bounce around a lot.

However, the "clear lock bit atomically and then test the waiters bit"
sequence turns out to be much more expensive than it needs to be,
because you get a nasty stall when trying to access the same word that
just got updated atomically.

On architectures where locking is done with LL/SC, this would be trivial
to fix with a new primitive that clears one bit and tests another
atomically, but that ends up not working on x86, where the only atomic
operations that return the result end up being cmpxchg and xadd.  The
atomic bit operations return the old value of the same bit we changed,
not the value of an unrelated bit.

On x86, we could put the lock bit in the high bit of the byte, and use
"xadd" with that bit (where the overflow ends up not touching other
bits), and look at the other bits of the result.  However, an even
simpler model is to just use a regular atomic "and" to clear the lock
bit, and then the sign bit in eflags will indicate the resulting state
of the unrelated bit #7.

So by moving the PageWaiters bit up to bit #7, we can atomically clear
the lock bit and test the waiters bit on x86 too.  And architectures
with LL/SC (which is all the usual RISC suspects), the particular bit
doesn't matter, so they are fine with this approach too.

This avoids the extra access to the same atomic word, and thus avoids
the costly stall at page unlock time.

The only downside is that the interface ends up being a bit odd and
specialized: clear a bit in a byte, and test the sign bit.  Nick doesn't
love the resulting name of the new primitive, but I'd rather make the
name be descriptive and very clear about the limitation imposed by
trying to work across all relevant architectures than make it be some
generic thing that doesn't make the odd semantics explicit.

So this introduces the new architecture primitive

    clear_bit_unlock_is_negative_byte();

and adds the trivial implementation for x86.  We have a generic
non-optimized fallback (that just does a "clear_bit()"+"test_bit(7)"
combination) which can be overridden by any architecture that can do
better.  According to Nick, Power has the same hickup x86 has, for
example, but some other architectures may not even care.

All these optimizations mean that my page locking stress-test (which is
just executing a lot of small short-lived shell scripts: "make test" in
the git source tree) no longer makes our page locking look horribly bad.
Before all these optimizations, just the unlock_page() costs were just
over 3% of all CPU overhead on "make test".  After this, it's down to
0.66%, so just a quarter of the cost it used to be.

(The difference on NUMA is bigger, but there this micro-optimization is
likely less noticeable, since the big issue on NUMA was not the accesses
to 'struct page', but the waitqueue accesses that were already removed
by Nick's earlier commit).

Pull networking fixes from David Miller:

 1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar.

    The most important is to not assume the packet is RX just because
    the destination address matches that of the device. Such an
    assumption causes problems when an interface is put into loopback
    mode.

 2) If we retry when creating a new tc entry (because we dropped the
    RTNL mutex in order to load a module, for example) we end up with
    -EAGAIN and then loop trying to replay the request. But we didn't
    reset some state when looping back to the top like this, and if
    another thread meanwhile inserted the same tc entry we were trying
    to, we re-link it creating an enless loop in the tc chain. Fix from
    Daniel Borkmann.

 3) There are two different WRITE bits in the MDIO address register for
    the stmmac chip, depending upon the chip variant. Due to a bug we
    could set them both, fix from Hock Leong Kweh.

The commit 55ee7017ee31 ("arm: omap2: board-generic: use

clocksource devices for AM437x from OMAP GP Timer to SyncTimer32K.

Unfortunately, the SyncTimer32K is starving from frequency deviation
as mentioned in commit 5b5c01359152 ("ARM: OMAP2+: AM43x: Use gptimer
as clocksource") and, as reported by Franklin [1], even its monotonic
nature is under question (most probably there is a HW issue, but it's
still under investigation).

Taking into account above facts It's reasonable to rollback to the use
of omap3_gptimer_timer_init().

commit f23bc46c30ca5ef58b8549434899fcbac41b2cfc.

df30f7408b openvswitch: upcall: Fix vlan handling.
Networking stack accelerate vlan tag handling by
keeping topmost vlan header in skb. This works as
long as packet remains in OVS datapath. But during
OVS upcall vlan header is pushed on to the packet.
When such packet is sent back to OVS datapath, core
networking stack might not handle it correctly. Following
patch avoids this issue by accelerating the vlan tag
during flow key extract. This simplifies datapath by
bringing uniform packet processing for packets from
all code paths.

Fixes: 5108bbaddc ("openvswitch: add processing of L3 packets").

56ab6b9300 ipv4: Namespaceify tcp_tw_reuse knob
Different namespaces might have different requirements to reuse
TIME-WAIT sockets for new connections. This might be required in
cases where different namespace applications are in place which
require TIME_WAIT socket connections to be reduced independently
of the host.

ce95077d0c ARM: dts: am4372: Add an empty chosen node to top level DTSI
Commit 75813028bbd7 ("ARM: dts: am4372: Remove skeleton.dtsi usage")
removed the skeleton.dtsi usage since we want to get rid of it.

But this can cause issues when booting a kernel with a boot-loader
that doesn't create a chosen node if this isn't present in the DTB
since the decompressor relies on a pre-existing chosen node to be
available to insert the command line and merge other ATAGS info.
