8e2fed1c0c openvswitch: Serialize acts with original netlink len
Previously, we used the kernel-internal netlink actions length to
calculate the size of messages to serialize back to userspace.
However,the sw_flow_actions may not be formatted exactly the same as the
actions on the wire, so store the original actions length when
de-serializing and re-use the original length when serializing.

402bae597e nfit: Clarify memory device state flags strings
ACPI 6.0 NFIT Memory Device State Flags in Table 5-129 defines
NVDIMM status as follows.  These bits indicate multiple info,
such as failures, pending event, and capability.

  Bit [0] set to 1 to indicate that the previous SAVE to the
  Memory Device failed.
  Bit [1] set to 1 to indicate that the last RESTORE from the
  Memory Device failed.
  Bit [2] set to 1 to indicate that platform flush of data to
  Memory Device failed. As a result, the restored data content
  may be inconsistent even if SAVE and RESTORE do not indicate
  failure.
  Bit [3] set to 1 to indicate that the Memory Device is observed
  to be not armed prior to OSPM hand off. A Memory Device is
  considered armed if it is able to accept persistent writes.
  Bit [4] set to 1 to indicate that the Memory Device observed
  SMART and health events prior to OSPM handoff.

/sys/bus/nd/devices/nmemX/nfit/flags shows this flags info.
The output strings associated with the bits are "save", "restore",
"smart", etc., which can be confusing as they may be interpreted
as positive status, i.e. save succeeded.

Change also the dev_info() message in acpi_nfit_register_dimms()
to be consistent with the sysfs flags strings.

538e456319 bgmac: support up to 3 cores (devices) on a bus
Broadcom buses may have more than 1 Ethernet device. This is used e.g.
to have few interfaces connected to different switch ports. So far we
saw chipsets with only 2 devices (e.g. BCM4706) but recent ones have
up to 3 (e.g. Netgear R8000 uses 3rd interface for most of switch
traffic, lower interfaces are for some kind of offloading).

a5256f7e74 batman-adv: don't access unregistered net_device object
In batadv_hardif_disable_interface() there is a call to
batadv_softif_destroy_sysfs() which in turns invokes
unregister_netdevice() on the soft_iface.
After this point we cannot rely on the soft_iface object
anymore because it might get free'd by the netdev periodic
routine at any time.

For this reason the netdev_upper_dev_unlink(.., soft_iface) call
is moved before the invocation of batadv_softif_destroy_sysfs() so
that we can be sure that the soft_iface object is still valid.

Pull amr64 kvm fix from Will Deacon:
 "We've uncovered a nasty bug in the arm64 KVM code which allows a badly
  behaved 32-bit guest to bring down the host.  The fix is simple (it's
  what I believe we call a "brown paper bag" bug) and I don't think it
  makes sense to sit on this, particularly as Russell ended up
  triggering this rather than just somebody noticing a potential problem
  by inspection.

  Usually arm64 KVM changes would go via Paolo's tree, but he's on
  holiday at the moment and the deal is that anything urgent gets
  shuffled via the arch trees, so here it is.

126c69a0bd arm64: KVM: Fix host crash when injecting a fault into a 32bit guest
When injecting a fault into a misbehaving 32bit guest, it seems
rather idiotic to also inject a 64bit fault that is only going
to corrupt the guest state. This leads to a situation where we
perform an illegal exception return at EL2 causing the host
to crash instead of killing the guest.

Just fix the stupid bug that has been there from day 1.

port so that the driver can track which ports are in use.  There's
no need to log this - it just fills the system log with useless and

Also, when failing to init SR-IOV interfaces the driver was printing the
same message twice. Just remove the inner printk and let the outer message

1afe839e6b netfilter: ip6t_REJECT: added missing icmpv6 codes
RFC 4443 added two new codes values for ICMPv6 type 1:

 5 - Source address failed ingress/egress policy
 6 - Reject route to destination

And RFC 7084 states in L-14 that IPv6 Router MUST send ICMPv6 Destination
Unreachable with code 5 for packets forwarded to it that use an address
from a prefix that has been invalidated.

Codes 5 and 6 are more informative subsets of code 1.

Pull block fixes from Jens Axboe:
 "Two fixes in this pull request:

   - The writeback regression fix from Tejun, which has been weeks in
     the making.  This fixes a case where we would sometimes not issue
     writeback when we should have.

   - An older fix for a memory corruption issue in mtip32xx.  It was
     deferred since we wanted a better fix for this (driver should not
     have to handle that case), but given the timing, it's better to put
     the simple fix in for 4.2 release"

8c5bbe77d4 Merge branch 'act_bpf_lockless'
Alexei Starovoitov says:

====================
act_bpf: remove spinlock in fast path

v1 version had a race condition in cleanup path of bpf_prog.
I tried to fix it by adding new callback 'cleanup_rcu' to 'struct tcf_common'
and call it out of act_api cleanup path, but Daniel noticed
(thanks for the idea!) that most of the classifiers already do action cleanup
out of rcu callback.
So instead this set of patches converts tcindex and rsvp classifiers to call
tcf_exts_destroy() after rcu grace period and since action cleanup logic
in __tcf_hash_release() is only called when bind and refcnt goes to zero,
it's guaranteed that cleanup() callback is called from rcu callback.
More specifically:
patches 1 and 2 - simple fixes
patches 2 and 3 - convert tcf_exts_destroy in tcindex and rsvp to call_rcu
patch 5 - removes spin_lock from act_bpf

The cleanup of actions is now universally done after rcu grace period
and in the future we can drop (now unnecessary) call_rcu from tcf_hash_destroy()
patch 5 is using synchronize_rcu() in act_bpf replacement path, since it's
very rare and alternative of dynamically allocating 'struct tcf_bpf_cfg' just
to pass it to call_rcu looks even less appealing.

cff82457c5 net_sched: act_bpf: remove spinlock in fast path
Similar to act_gact/act_mirred, act_bpf can be lockless in packet processing
with extra care taken to free bpf programs after rcu grace period.
Replacement of existing act_bpf (very rare) is done with synchronize_rcu()
and final destruction is done from tc_action_ops->cleanup() callback that is
called from tcf_exts_destroy()->tcf_action_destroy()->__tcf_hash_release() when
bind and refcnt reach zero which is only possible when classifier is destroyed.
Previous two patches fixed the last two classifiers (tcindex and rsvp) to
call tcf_exts_destroy() from rcu callback.

Similar to gact/mirred there is a race between prog->filter and
prog->tcf_action. Meaning that the program being replaced may use
previous default action if it happened to return TC_ACT_UNSPEC.
act_mirred race betwen tcf_action and tcfm_dev is similar.
In all cases the race is harmless.
Long term we may want to improve the situation by replacing the whole
tc_action->priv as single pointer instead of updating inner fields one by one.

4d9aac397a powerpc/PCI: Disable MSI/MSI-X interrupts at PCI probe time in OF case
Since commit 1851617cd2 ("PCI/MSI: Disable MSI at enumeration even if
kernel doesn't support MSI"), the setup of dev->msi_cap/msix_cap and the
disable of MSI/MSI-X interrupts isn't being done at PCI probe time, as
the logic responsible for this was moved in the aforementioned commit
from pci_device_add() to pci_setup_device(). The latter function is not
reachable on PowerPC pseries platform during Open Firmware PCI probing
time.

This exhibits as drivers not being able to enable MSI, eg:

  bnx2x 0000:01:00.0: no msix capability found

This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X
during PCI probe time on pSeries platform.

22b6839b91 PCI: Make pci_msi_setup_pci_dev() non-static for use by arch code
Commit 1851617cd2 ("PCI/MSI: Disable MSI at enumeration even if kernel
doesn't support MSI") changed the location of the code that initialises
dev->msi_cap/msix_cap and then disables MSI/MSI-X interrupts at PCI
probe time in devices that have this flag set. It moved the code from
pci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(),
called by pci_setup_device().

The pseries PCI probing code does not call pci_setup_device(), so since
the aforementioned commit the function pci_msi_setup_pci_dev() is not
called and MSI/MSI-X interrupts are left enabled. Additionally because
dev->msi_cap/msix_cap are not initialised no driver can ever enable
MSI/MSI-X.

To fix this, the pseries PCI probe should manually call
pci_msi_setup_pci_dev(), so this patch makes it non-static.

36582e5d4d ath10k: add qca6164 support
This adds additional 0x0041 PCI Device ID
definition to ath10k for QCA6164 which is a 1
spatial stream sibling of the QCA6174 (which is 2
spatial stream chip).

The QCA6164 needs a dedicated board.bin file which
is different than the one used for QCA6174. If the
board.bin is wrong the device will crash early
while trying to boot firmware. The register dump
will look like this:

 ath10k_pci 0000:02:00.0: firmware register dump:
 ath10k_pci 0000:02:00.0: [00]: 0x05010000 0x000015B3 0x000A012D 0x00955B31
 ...

Note the value 0x000A012D.
