1bde33e051 include/linux/gfp.h: fix ___GFP_NOLOCKDEP value
Igor Stoppa has noticed that __GFP_NOLOCKDEP can use a lower bit.  At
the time commit 7e7844226f ("lockdep: allow to disable reclaim lockup
detection") was written we still had __GFP_OTHER_NODE but I have removed
it in commit 41b6167e8f ("mm: get rid of __GFP_OTHER_NODE") and forgot
to lower the bit value.

The current value is outside of __GFP_BITS_SHIFT so it cannot be used
actually.

Pull pin control fixes from Linus Walleij:
 "Here is an overdue pull request for pin control fixes, the most
  prominent feature is to make Intel Chromebooks (and I suspect any
  other Cherryview-based Intel thing) happy again, which we really want
  to see.

  There is a patch hitting drivers/firmware/* that I was uncertain to
  who actually manages, but I got Andy Shevchenko's and Dmitry Torokov's
  review tags on it and I trust them both 100% to do the right thing for
  Intel platform drivers.

  Summary:

   - Make a few Intel Chromebooks with Cherryview DMI firmware work
     smoothly.

   - A fix for some bogus allocations in the generic group management
     code.

   - Some GPIO descriptor lookup table stubs. Merged through the pin
     control tree for administrative reasons.

   - Revert the "bi-directional" and "output-enable" generic properties:
     we need more discussions around this. It seems other SoCs are using
     input/output gate enablement and these terms are not correct.

   - Fix mux and drive strength atomically in the MXS driver.

   - Fix the SPDIF function on sunxi A83T.

   - OF table terminators and other small fixes"

2) Various PTR_TO_MAP_VALUE_OR_NULL tests to make sure pointer

3) Test cases for the special treatment of LD_ABS/LD_IND to
   make sure verifier doesn't break calling convention here.

b8cb5a545c ext4: fix quota charging for shared xattr blocks
ext4_xattr_block_set() calls dquot_alloc_block() to charge for an xattr
block when new references are made. However if dquot_initialize() hasn't
been called on an inode, request for charging is effectively ignored
because ext4_inode_info->i_dquot is not initialized yet.

35d2f80b07 vlan: Fix tcp checksum offloads in Q-in-Q vlans
It appears that TCP checksum offloading has been broken for
Q-in-Q vlans.  The behavior was execerbated by the
series
    commit afb0bc972b ("Merge branch 'stacked_vlan_tso'")
that that enabled accleleration features on stacked vlans.

However, event without that series, it is possible to trigger
this issue.  It just requires a lot more specialized configuration.

The root cause is the interaction between how
netdev_intersect_features() works, the features actually set on
the vlan devices and HW having the ability to run checksum with
longer headers.

The issue starts when netdev_interesect_features() replaces
NETIF_F_HW_CSUM with a combination of NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM,
if the HW advertises IP|IPV6 specific checksums.  This happens
for tagged and multi-tagged packets.   However, HW that enables
IP|IPV6 checksum offloading doesn't gurantee that packets with
arbitrarily long headers can be checksummed.

This patch disables IP|IPV6 checksums on the packet for multi-tagged
packets.

41c25707d2 cpuset: consider dying css as offline
In most cases, a cgroup controller don't care about the liftimes of
cgroups.  For the controller, a css becomes online when ->css_online()
is called on it and offline when ->css_offline() is called.

However, cpuset is special in that the user interface it exposes cares
whether certain cgroups exist or not.  Combined with the RCU delay
between cgroup removal and css offlining, this can lead to user
visible behavior oddities where operations which should succeed after
cgroup removals fail for some time period.  The effects of cgroup
removals are delayed when seen from userland.

This patch adds css_is_dying() which tests whether offline is pending
and updates is_cpuset_online() so that the function returns false also
while offline is pending.  This gets rid of the userland visible
delays.

73dd3a4839 net/mlx5: Avoid using pending command interface slots
Currently when firmware command gets stuck or it takes long time to
complete, the driver command will get timeout and the command slot is
freed and can be used for new commands, and if the firmware receive new
command on the old busy slot its behavior is unexpected and this could
be harmful.
To fix this when the driver command gets timeout we return failure,
but we don't free the command slot and we wait for the firmware to
explicitly respond to that command.
Once all the entries are busy we will stop processing new firmware
commands.

c70d9d809f ptrace: Properly initialize ptracer_cred on fork
When I introduced ptracer_cred I failed to consider the weirdness of
fork where the task_struct copies the old value by default.  This
winds up leaving ptracer_cred set even when a process forks and
the child process does not wind up being ptraced.

Because ptracer_cred is not set on non-ptraced processes whose
parents were ptraced this has broken the ability of the enlightenment

Fix this by properly initializing ptracer_cred in ptrace_init_task

This must be done with a little bit of care to preserve the current value
of ptracer_cred when ptrace carries through fork.  Re-reading the
ptracer_cred from the ptracing process at this point is inconsistent
with how PT_PTRACE_CAP has been maintained all of these years.

c61872c983 firmware: dmi: Add DMI_PRODUCT_FAMILY identification string
Sometimes it is more convenient to be able to match a whole family of
products, like in case of bunch of Chromebooks based on Intel_Strago to
apply a driver quirk instead of quirking each machine one-by-one.

This adds support for DMI_PRODUCT_FAMILY identification string and also
exports it to the userspace through sysfs attribute just like the
existing ones.

====================
Netfilter/IPVS fixes for net

The following patchset contains Netfilter/IPVS fixes for your net tree,
they are:

1) When using IPVS in direct-routing mode, normal traffic from the LVS
   host to a back-end server is sometimes incorrectly NATed on the way
   back into the LVS host. Patch to fix this from Julian Anastasov.

2) Calm down clang compilation warning in ctnetlink due to type
   mismatch, from Matthias Kaehlcke.

3) Do not re-setup NAT for conntracks that are already confirmed, this
   is fixing a problem that was introduced in the previous nf-next batch.
   Patch from Liping Zhang.

4) Do not allow conntrack helper removal from userspace cthelper
   infrastructure if already in used. This comes with an initial patch
   to introduce nf_conntrack_helper_put() that is required by this fix.
   From Liping Zhang.

5) Zero the pad when copying data to userspace, otherwise iptables fails
   to remove rules. This is a follow up on the patchset that sorts out
   the internal match/target structure pointer leak to userspace. Patch
   from the same author, Willem de Bruijn. This also comes with a build
   failure when CONFIG_COMPAT is not on, coming in the last patch of
   this series.

6) SYNPROXY crashes with conntrack entries that are created via
   ctnetlink, more specifically via conntrackd state sync. Patch from
   Eric Leblond.

7) RCU safe iteration on set element dumping in nf_tables, from
   Liping Zhang.

8) Missing sanitization of immediate date for the bitwise and cmp
   expressions in nf_tables.

9) Refcounting logic for chain and objects from set elements does not
   integrate into the nf_tables 2-phase commit protocol.

10) Missing sanitization of target verdict in ebtables arpreply target,
    from Gao Feng.

 "We had a small batch of fixes before -rc1, but here is a larger one.
  It contains a backmerge of 4.12-rc1 since some of the downstream
  branches we merge had that as base; at the same time we already had
  merged contents before -rc1 and rebase wasn't the right solution.

  A mix of random smaller fixes and a few things worth pointing out:

   - We've started telling people to avoid cross-tree shared branches if
     all they're doing is picking up one or two DT-used constants from a
     shared include file, and instead to use the numeric values on first
     submission. Follow-up moving over to symbolic names are sent in
     right after -rc1, i.e. here. It's only a few minor patches of this
     type.

   - Linus Walleij and others are resurrecting the 'Gemini' platform,
     and wanted a cut-down platform-specific defconfig for it. So I
     picked that up for them.

   - Rob Herring ran 'savedefconfig' on arm64, it's a bit churny but it
     helps people to prepare patches since it's a pain when defconfig
     and current savedefconfig contents differs too much.

   - Devicetree additions for some pinctrl drivers for Armada that were
     merged this window. I'd have preferred to see those earlier but
     it's not a huge deail.

  The biggest change worth pointing out though since it's touching other
  parts of the tree: We added prefixes to be used when cross-including
  DT contents between arm64 and arm, allowing someone to #include
  <arm/foo.dtsi> from arm64, and likewise. As part of that, we needed
  arm/foo.dtsi to work on arm as well. The way I suggested this to Heiko
  resulted in a recursive symlink.

  Instead, I've now moved it out of arch/*/boot/dts/include, into a
  shared location under scripts/dtc. While I was at it, I consolidated
  so all architectures now behave the same way in this manner.

  Rob Herring (DT maintainer) has acked it. I cc:d most other arch
  maintainers but nobody seems to care much; it doesn't really affect
  them since functionality is unchanged for them by default"

Once every driver currently using the tty_port_register_device() helpers

6a29beef9d usb: host: xhci-ring: don't need to clear interrupt pending for MSI enabled hcd
According to xHCI spec Figure 30: Interrupt Throttle Flow Diagram

	If PCI Message Signaled Interrupts (MSI or MSI-X) are enabled,
       	then the assertion of the Interrupt Pending (IP) flag in Figure 30
       	generates a PCI Dword write. The IP flag is automatically cleared
       	by the completion of the PCI write.

the MSI enabled HCs don't need to clear interrupt pending bit, but
hcd->irq = 0 doesn't equal to MSI enabled HCD. At some Dual-role
controller software designs, it sets hcd->irq as 0 to avoid HCD
requesting interrupt, and they want to decide when to call usb_hcd_irq
by software.

30e7d894c1 tracing/kprobes: Enforce kprobes teardown after testing
Enabling the tracer selftest triggers occasionally the warning in
text_poke(), which warns when the to be modified page is not marked
reserved.

The reason is that the tracer selftest installs kprobes on functions marked
__init for testing. These probes are removed after the tests, but that
removal schedules the delayed kprobes_optimizer work, which will do the
actual text poke. If the work is executed after the init text is freed,
then the warning triggers. The bug can be reproduced reliably when the work
delay is increased.

Flush the optimizer work and wait for the optimizing/unoptimizing lists to
become empty before returning from the kprobes tracer selftest. That
ensures that all operations which were queued due to the probes removal
have completed.

c953d63548 ebtables: arpreply: Add the standard target sanity check
The info->target comes from userspace and it would be used directly.
So we need to add the sanity check to make sure it is a valid standard
target, although the ebtables tool has already checked it. Kernel needs
to validate anything coming from userspace.

If the target is set as an evil value, it would break the ebtables
and cause a panic. Because the non-standard target is treated as one
offset.

Now add one helper function ebt_invalid_target, and we would replace
the macro INVALID_TARGET later.
