8a68badd12 i40evf: free rings in remove function
When the i40evf_remove() calls netdev close, the device doesn't actually
close - it schedules the work for the watchdog to perform. Since we're
stopping the watchdog, this work doesn't get done. However, we're
resetting the part, so we can free resources after the reset request has
gone through. This plugs a memory leak.

03aa268b14 i40e: remove unnecessary call to i40e_update_link_info
This call is made just prior to running i40e_link_event. In
i40e_link_event, we set hw->phy.get_link_info to true just prior to
calling i40e_get_link_status, which conveniently runs
i40e_update_link_info for us. Thus, we are running i40e_update_link_info
twice, which seems like something we don't need to do...

1d68005db4 i40e: enable mc magic pkt wakeup during power down
This patch adds a call to the mac_address_write admin q function during
power down to update the PRTPM_SAH/SAL registers with the MC_MAG_EN bit
thus enabling multicast magic packet wakeup.

A FW workaround is needed to write the multicast magic wake up enable
bit in the PRTPM_SAH register. The FW expects the mac address write
admin q cmd to be called first with one of the WRITE_TYPE_LAA flags
and then with the multicast relevant flags.

*Note: This solution only works for X722 devices currently. A PFR will
clear the previously mentioned bit by default, but X722 has support for a
WOL_PRESERVE_ON_PFR flag which prevents the bit from being cleared. Once
other devices support this flag, this solution should work as well.

a410c821c0 i40e: fix disable overflow promiscuous mode
There exists a bug in which the driver is unable to exit overflow
promiscuous mode after having added "too many" mac filters.  It is
expected that after triggering overflow promiscuous, removing the
failed/extra filters should then disable overflow promiscuous mode.

The bug exists because we were intentionally skipping the sync_vsi_filter
path in cases where we were removing failed filters since they shouldn't
have been added to the firmware in the first place, however we still
need to go through the sync_vsi_filter code path to determine whether or
not it is ok to exit overflow promiscuous mode.  This patch fixes the
bug by making sure we go through the sync_vsi_filter path in cases of
failed filters.

2763f92f85 ARM: SoC fixes for v4.10
Two more bugfixes that came in during this week:
 
 - one defconfig change to enable a vital driver used on some Qualcomm
   based phones. This was already queued for 4.11, but the maintainer
   asked to have it in 4.10 after all.
 
 - One regression fix for the reset controller framework, this got
   broken by a typo in the 4.10 merge window.

lockdep to be enabled "current->lockdep_recursion == 0".

336a9cde10 hrtimer: Catch invalid clockids again
commit 82e88ff1ea94 ("hrtimer: Revert CLOCK_MONOTONIC_RAW support") removed
unfortunately a sanity check in the hrtimer code which was part of that
MONOTONIC_RAW patch series.

It would have caught the bogus usage of CLOCK_MONOTONIC_RAW in the wireless
code. So bring it back.

It is way too easy to take any random clockid and feed it to the hrtimer
subsystem. At best, it gets mapped to a monotonic base, but it would be
better to just catch illegal values as early as possible.
    
Detect invalid clockids, map them to CLOCK_MONOTONIC and emit a warning.

[ tglx: Replaced the BUG by a WARN and gracefully map to CLOCK_MONOTONIC ]

22f0708a71 vxlan: fix oops in dev_fill_metadata_dst
Since the commit 0c1d70af924b ("net: use dst_cache for vxlan device")
vxlan_fill_metadata_dst() calls vxlan_get_route() passing a NULL
dst_cache pointer, so the latter should explicitly check for
valid dst_cache ptr. Unfortunately the commit d71785ffc7e7 ("net: add
dst_cache to ovs vxlan lwtunnel") removed said check.

As a result is possible to trigger a null pointer access calling
vxlan_fill_metadata_dst(), e.g. with:

ovs-vsctl add-br ovs-br0
ovs-vsctl add-port ovs-br0 vxlan0 -- set interface vxlan0 \
	type=vxlan options:remote_ip=192.168.1.1 \
	options:key=1234 options:dst_port=4789 ofport_request=10
ip address add dev ovs-br0 172.16.1.2/24
ovs-vsctl set Bridge ovs-br0 ipfix=@i -- --id=@i create IPFIX \
	targets=\"172.16.1.1:1234\" sampling=1
iperf -c 172.16.1.1 -u -l 1000 -b 10M -t 1 -p 1234

This commit addresses the issue passing to vxlan_get_route() the
dst_cache already available into the lwt info processed by
vxlan_fill_metadata_dst().

sk_page_frag_refill() allocates either a compound page or an order-0
page. We can use page_ref_inc() which is slightly faster than get_page()

Prevent sending out a left-shifted sequence number from a Linux sender in

9c568fd884 sfc: do not device_attach if a reset is pending
efx_start_all can return without initialising queues as a reset is pending.
 This means that when netif_device_attach is called, the kernel can start
 sending traffic without having an initialised TX queue to send to.
This patch avoids this by not calling netif_device_attach if there is a
 pending reset.

0ccb998bf4 sfc: fix filter_id misinterpretation in edge case
On EF10, hardware filter IDs are 13 bits, but in some places we store
 32-bit "full filter IDs" in which higher order bits encode the filter
 match-priority.  This could cause a filter to have a full filter ID of
 0xffff, which is also the value EFX_EF10_FILTER_ID_INVALID which we use
 in 16-bit "short" filter IDs (without match-priority bits).  This would
 occur if the hardware filter ID was 0x1fff and the match-priority was 7.
Unfortunately, some code that checks for EFX_EF10_FILTER_ID_INVALID can
 be called on full filter IDs, and will WARN_ON if this ever happens.
So, since we have plenty of spare bits in the full filter ID, this patch
 shifts the priority bits left one bit when constructing the full filter
 IDs, ensuring that the 0x2000 bit of a full filter ID will always be 0
 and thus no full filter ID can ever equal EFX_EF10_FILTER_ID_INVALID.

This patch also replaces open-coded full<->short filter ID conversions
 with calls to functions, thus keeping the definition of the full filter
 ID format in one place.

fbdf0e28d0 vmxnet3: prevent building with 64K pages
I got a warning about broken code on ARM64 with 64K pages:

drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init':
drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow]
    rq->buf_info[0][i].len = PAGE_SIZE;

'len' here is a 16-bit integer, so this clearly won't work. I don't think
this driver is used much on anything other than x86, so there is no need
to fix this properly and we can work around it with a Kconfig dependency
to forbid known-broken configurations. qemu in theory supports it on
other architectures too, but presumably only for compatibility with x86
guests that also run on vmware.

CONFIG_PAGE_SIZE_64KB is used on hexagon, mips, sh and tile, the other
symbols are architecture-specific names for the same thing.

The qdisc_stab_lock is used in qdisc_get_stab and qdisc_put_stab.
These two functions are invoked in qdisc_create, qdisc_change, and
qdisc_destroy which run fully under RTNL.

So it already makes sure only one could access the qdisc_stab_list at

IFLA_PORT_VSI_TYPE and struct ifla_port_vsi are not used anywhere in

7520872c0c block: don't defer flushes on blk-mq + scheduling
For blk-mq with scheduling, we can potentially end up with ALL
driver tags assigned and sitting on the flush queues. If we
defer because of an inlfight data request, then we can deadlock
if that data request doesn't already have a tag assigned.

This fixes a deadlock with running the xfs/297 xfstest, where
thousands of syncs can cause the drive queue to stall.

But if we do have work leftover but didn't dispatch anything,
