not sure why it didn't. Anyway, I bisected that to:
commit 6d18c732b95c0a9d35e9f978b4438bba15412284
Author: Xin Long <lucien.xin@gmail.com>

bridge: start hello_timer when enabling KERNEL_STP in br_stp_start
Since commit 76b91c32dd86 ("bridge: stp: when using userspace stp stop
kernel hello and hold timers"), bridge would not start hello_timer if
stp_enabled is not KERNEL_STP when br_dev_open.
The problem is even if users set stp_enabled with KERNEL_STP later,
the timer will still not be started. It causes that KERNEL_STP can
not really work. Users have to re-ifup the bridge to avoid this.
This patch is to fix it by starting br->hello_timer when enabling
KERNEL_STP in br_stp_start.
As an improvement, it's also to start hello_timer again only when
br->stp_enabled is KERNEL_STP in br_hello_timer_expired, there is
no reason to start the timer again when it's NO_STP.
Fixes: 76b91c32dd86 ("bridge: stp: when using userspace stp stop kernel hello and hold timers")

No clue why this broke my system. I reverted that commit on top of v4.12-rc3-11-gf511c0b
to be extra sure and it booted normally.
Full dmesg, config, and bisect log are attached.

This seems fine to me, as long as you call tcp_mtup_init() after setting
the mss_clamp, whichy you are, everything should be alright.

I guess next time around we should do even less, i.e. report the
regression + bisect and then escalate this until the netdev folks fix
it on their own?
Like Jani said every -rc1 a pile of our CI machines keel over, and
unfortunately this patch here isn't the only one which seems to not
really move anywhere.

I have the feeling that ip_mc_clear_src() is called too soon.
We should call it once all users have released their reference.
I am not sure we have to call it after the RCU grace period,
more analysis of the code is needed.

The unwind failures stems from commit 2800209994f8 ("e1000e: Refactor PM

behaviour.

When our CI hits tons of non-drm issues every merge window, I imagine
our developers can start to get a little frustrated trying to get them
fixed. Especially so when valid fixes like this get blocked by silly
bikesheds from developers who don't even seem to have very many
contributions upstream, and the maintainers don't respond. We have
enough on our plates trying to get our own stuff fixed.
While I understand why our developers aren't willing to jump through all
the hoops, updated patch follows. Please let's move on.
BR,
Jani.

I think releasing the lock possibly is fine. It certainly is better than
sleeping with a lock held.
We disabled the device interrupts just before this line.
However I think the synchronize_irq should be outside of the
conditional right after the write to B43legacy_MMIO_GEN_IRQ_MASK. (So
two lines above)
I don't think it makes sense to only synchronize if BSS_CHANGED_BSSID
is set.
On the other hand b43 does not have this irq-disabling foobar anymore.
So somebody must have removed it. Maybe you can find the commit that
removed this stuff from b43 and port it to b43legacy?
So I would vote for moving the synchronize_irq up outside of the
conditional and put the unlock/lock sequence around it.
And as a second patch on top of that try to remove this stuff
altogether like b43 did.

Overly aggressive garbage collection will delete other (non-FAILED)
entries as well, and can trigger needless re-ARP (or re-ND), whereas
the admin may just want to lose some selective static arp/NCE entries.

* [PATCH net-next] neigh: Really delete an arp/neigh entry on "ip neigh delete" or "arp -d"
From: Sowmini Varadhan @ 2017-05-30 19:52 UTC (permalink / raw)
To: netdev, sowmini.varadhan; +Cc: davem, stephen, sowmini.varadhan
The command
# arp -s 62.2.0.1 a:b:c:d:e:f dev eth2
adds an entry like the following (listed by "arp -an")
? (62.2.0.1) at 0a:0b:0c:0d:0e:0f [ether] PERM on eth2
but the symmetric deletion command
# arp -i eth2 -d 62.2.0.1
does not remove the PERM entry from the table, and instead leaves behind
? (62.2.0.1) at <incomplete> on eth2
The reason is that there is a refcnt of 1 for the arp_tbl itself
(neigh_alloc starts off the entry with a refcnt of 1), thus
the neigh_release() call from arp_invalidate() will (at best) just
decrement the ref to 1, but will never actually free it from the
table.
To fix this, we need to do something like neigh_forced_gc: if
the refcnt is 1 (i.e., on the table's ref), remove the entry from
the table and free it. This patch refactors and shares common code
between neigh_forced_gc() and the newly added neigh_remove_one().
A similar issue exists for IPv6 Neighbor Cache entries, and is fixed
in a similar manner by this patch.

Interference mitigation has never been properly implemented and tested.
As such nobody should use it and I would be surprised if anybody uses
this attribute.
So I would suggest to remove this sysfs attribute entirely instead of
having this incorrect fix.

* [PATCH net-next 7/9] nfp: move bpf offload code to the BPF app
From: Jakub Kicinski @ 2017-05-31 15:06 UTC (permalink / raw)
To: netdev; +Cc: oss-drivers, Jakub Kicinski
In-Reply-To: <20170531150651.16873-1-jakub.kicinski@netronome.com>
Move bulk of the eBPF offload code out of common vNIC code into
app-specific callbacks.

* [PATCH net-next 6/9] nfp: move eBPF offload files to BPF app directory
From: Jakub Kicinski @ 2017-05-31 15:06 UTC (permalink / raw)
To: netdev; +Cc: oss-drivers, Jakub Kicinski
In-Reply-To: <20170531150651.16873-1-jakub.kicinski@netronome.com>
Pure move of eBPF offload files to BPF app directory,
only change the names and relative header location.
nfp_asm.h stays in the main dir and it doesn't really
have to include nfp_bpf.h.

* [PATCH net-next 4/9] nfp: move port init to apps
From: Jakub Kicinski @ 2017-05-31 15:06 UTC (permalink / raw)
To: netdev; +Cc: oss-drivers, Jakub Kicinski
In-Reply-To: <20170531150651.16873-1-jakub.kicinski@netronome.com>
Start fleshing out the apps by turning the vNIC init code to
a per-app callback. The two initial apps we have are NIC and
eBPF.

* [PATCH net-next 3/9] nfp: turn reading PCIe RTsym parameters into a helper
From: Jakub Kicinski @ 2017-05-31 15:06 UTC (permalink / raw)
To: netdev; +Cc: oss-drivers, Jakub Kicinski
In-Reply-To: <20170531150651.16873-1-jakub.kicinski@netronome.com>
Turn the function to read number of ports into a generic helper.
While at it make sure we propagate all errors other than -ENOENT.

* [PATCH net-next 1/9] sched: add helper for updating statistics on all actions

Forgetting to disable preemption around tcf_action_stats_update()
seems to be a common mistake. Add a helper function for updating
stats on all actions of a filter.

* [PATCH net-next 0/9] nfp: move BPF offload code into app
From: Jakub Kicinski @ 2017-05-31 15:06 UTC (permalink / raw)
To: netdev; +Cc: oss-drivers, Jakub Kicinski
Hi!
This series moves the eBPF offload code out of netdev/vNIC handling and
starts building the nfp_app. Port init is moved into the apps as well
because various apps associate vNICs, representors with ports differently.
First patch adds a helper for updating tc stats which has been waiting
in my tree to be included in any moderately related series.
Next series will bring communicating with FW using control messages,
then representors, BPF maps, tc flower... :)
Jakub Kicinski (9):
sched: add helper for updating statistics on all actions
nfp: add missing fall through statements
nfp: turn reading PCIe RTsym parameters into a helper
nfp: move port init to apps
nfp: report app name in ethtool -i
nfp: move eBPF offload files to BPF app directory
nfp: move bpf offload code to the BPF app
nfp: move basic eBPF stats to app-specific code
nfp: fix memory leak on FW load error
