====================
40GbE Intel Wired LAN Driver Updates 2018-03-19
This series contains updates to i40e and i40evf only.
Alex fixes a potential deadlock in the configure_clsflower function in
i40evf, where we exit with the "IN_CRITICAL_TASK" bit set while
notifying the PF of flower filters.
Jan fixed an issue where it was possible to set a mode that is not
allowed which resulted in link being down, so fixed the parity between
i40e_set_link_ksettings() and i40e_get_link_ksettings().
Patryk fixes a bug where a backplane device was allowing the setting of
link settings, which is not allowed.
Shiraz fixes a crash when entering S3 because the client interface was
freeing the MSIx vectors while they are still in use.
Jake fixes up a function header comment to document a newly added
parameter. Also cleaned up flags that were never used.
Doug fixes the incorrect return type for i40e_aq_add_cloud_filters().

grace periods
percpu_ref internally uses sched-RCU to implement the percpu -> atomic
mode switching and the documentation suggested that this could be
depended upon. This doesn't seem like a good idea.
* percpu_ref uses sched-RCU which has different grace periods regular
RCU. Users may combine percpu_ref with regular RCU usage and
incorrectly believe that regular RCU grace periods are performed by
percpu_ref. This can lead to, for example, use-after-free due to
premature freeing.
* percpu_ref has a grace period when switching from percpu to atomic
mode. It doesn't have one between the last put and release. This
distinction is subtle and can lead to surprising bugs.
* percpu_ref allows starting in and switching to atomic mode manually
for debugging and other purposes. This means that there may not be
any grace periods from kill to release.
This patch makes it clear that the grace periods are percpu_ref's
internal implementation detail and can't be depended upon by the
users.

In case of memory deficit and low percpu memory pages,
pcpu_balance_workfn() takes pcpu_alloc_mutex for a long
time (as it makes memory allocations itself and waits
for memory reclaim). If tasks doing pcpu_alloc() are
choosen by OOM killer, they can't exit, because they
are waiting for the mutex.
The patch makes pcpu_alloc() to care about killing signal
and use mutex_lock_killable(), when it's allowed by GFP
flags. This guarantees, a task does not miss SIGKILL
from OOM killer.

When commit 9c7be59fc519af ("libata: Apply NOLPM quirk to Crucial MX100
512GB SSDs") was added it inherited the ATA_HORKAGE_NO_NCQ_TRIM quirk
from the existing "Crucial_CT*MX100*" entry, but that entry sets model_rev
to "MU01", where as the entry adding the NOLPM quirk sets it to NULL.
This means that after this commit we no apply the NO_NCQ_TRIM quirk to
all "Crucial_CT512MX100*" SSDs even if they have the fixed "MU02"
firmware. This commit splits the "Crucial_CT512MX100*" quirk into 2
quirks, one for the "MU01" firmware and one for all other firmware
versions, so that we once again only apply the NO_NCQ_TRIM quirk to the
"MU01" firmware version.

Commit b17e5729a630 ("libata: disable LPM for Crucial BX100 SSD 500GB
drive"), introduced a ATA_HORKAGE_NOLPM quirk for Crucial BX100 500GB SSDs
but limited this to the MU02 firmware version, according to:
http://www.crucial.com/usa/en/support-ssd-firmware
MU02 is the last version, so there are no newer possibly fixed versions
and if the MU02 version has broken LPM then the MU01 almost certainly
also has broken LPM, so this commit changes the quirk to apply to all
firmware versions.

There have been reports of the Crucial M500 480GB model not working
with LPM set to min_power / med_power_with_dipm level.
It has not been tested with medium_power, but that typically has no
measurable power-savings.
Note the reporters Crucial_CT480M500SSD3 has a firmware version of MU03
and there is a MU05 update available, but that update does not mention any
LPM fixes in its changelog, so the quirk matches all firmware versions.
In my experience the LPM problems with (older) Crucial SSDs seem to be
limited to higher capacity versions of the SSDs (different firmware?),
so this commit adds a NOLPM quirk for the 480 and 960GB versions of the
M500, to avoid LPM causing issues with these SSDs.

Revert commit c68f0676ef7d ("ACPI / battery: Add quirk for Asus
GL502VSK and UX305LA") and commit 4446823e2573 ("ACPI / battery: Add
quirk for Asus UX360UA and UX410UAK").
On many many Asus products, the battery is sometimes reported as
charging or discharging even when it is full and you are on AC power.
This change quirked the kernel to avoid advertising the discharging
state when this happens on 4 laptop models, under the belief that
this was incorrect information. I presume it originates from user
reports who are confused that their battery status icon says that it
is discharging.
However, the reported information is indeed correct, and the quirk
approach taken is inadequate and more thought is needed first.
Specifically:
1. It only quirks discharging state, not charging
2. There are so many different Asus products and DMI naming variants
within those product families that behave this way; Linux could
grow to quirk hundreds of products and still not even be close at
"winning" this battle.
3. Asus previously clarified that this behaviour is intentional. The
platform will periodically do a partial discharge/charge cycle
when the battery is full, because this is one way to extend the
lifetime of the battery (leaving a battery at 100% charge and
unused will decrease its usable capacity over time).
My understanding is that any decent consumer product will have
this behaviour, but it appears that Asus is different in that
they expose this info through ACPI.
However, the behaviour seems correct. The ACPI spec does not
suggest in that the platform should hide the truth. It lets you
report that the battery is full of charge, and discharging, and
with external power connected; and Asus does this.
4. In terms of not confusing the user, this seems like something that
could/should be handled by userspace, which can also detect these
same (accurate) conditions in the general case.
Revert this quirk before it gets included in a release, while we look
for better approaches.

Since commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled
state in drm_atomic_remove_fb, v2."), removing the last framebuffer will
no longer disable the corresponding pipeline, which causes the KMS core
to complain about leaked connectors on driver unbind.
Fix this by calling drm_atomic_helper_shutdown() on driver unbind, which
will cause all display pipelines to be shut down and therefore drop the
extra references on the connectors.

====================
Automatic PHY interrupts
Now that the mv88e6xxx driver either installs in interrupt handler, or
polls for interrupts, it is possible to always handle PHY interrupts,
rather than have phylib perform the polling. This speeds up detection
of link changes and reduces the load on the MDIO bus, which is
beneficial for PTP.
====================

When registering an MDIO bus, it is possible to pass an array of
interrupts, one per address on the bus. phylib will then associate the
interrupt to the PHY device, if no other interrupt is provided.

MDIO bus structure.

With the recent change to polling for interrupts, it is important that

batadv_check_unicast_ttvn may redirect a packet to itself or another
originator. This involves rewriting the ttvn and the destination address in
the batadv unicast header. These field were not yet pulled (with skb rcsum
update) and thus any change to them also requires a change in the receive
checksum.

Stefano Brivio says:
====================
selftests: pmtu: Add further vti/vti6 MTU and PMTU tests
Patches 5/10 to 10/10 add tests to verify default MTU assignment
for vti4 and vti6 interfaces, to check that MTU values set on new
link and link changes are properly taken and validated, and to
verify PMTU exceptions on vti4 interfaces.
Patch 1/10 reverses function return codes as suggested by David
Ahern.
Patch 2/10 fixes the helper to fetch exceptions MTU to run in the
passed namespace.
Patches 3/10 and 4/10 are preparation work to make it easier to
introduce those tests.
v2: Reverse return codes, and make output prettier in 4/9 by
using padded printf, test descriptions and buffered error
strings. Remove accidental output to /dev/kmsg from 10/10
(was 9/9).

This test checks that MTU configured from userspace is used on
link creation and changes, and that when it's not passed from
userspace, it's calculated properly from the MTU of the lower
layer.

This test checks that MTU given on vti link creation is actually
configured, and that tunnel is not created with an invalid MTU
value.

This test checks that PMTU exceptions are created only when
needed on IPv4 routes with vti and xfrm, and their PMTU value is
checked as well.
We can't adopt the same approach as test_pmtu_vti6_exception()
here, because on IPv4 administrative MTU changes won't be
reflected directly on PMTU.
