40a7166044 net: dsa: mv88e6xxx: fix fid_mask when leaving bridge
The mv88e6xxx_priv_state structure contains an fid_mask, where 1 means
the FID is free to use, 0 means the FID is in use.

This patch fixes the bit clear in mv88e6xxx_leave_bridge() when
assigning a new FID to a port.

Example scenario: I have 7 ports, port 5 is CPU, port 6 is unused (no
PHY). After setting the ports 0, 1 and 2 in bridge br0, and ports 3 and
4 in bridge br1, I have the following fid_mask: 0b111110010110 (0xf96).

Indeed, br0 uses FID 0, and br1 uses FID 3.

After setting nomaster for port 0, I get the wrong fid_mask: 0b10 (0x2).

With this patch we correctly get 0b111110010100 (0xf94), meaning port 0
uses FID 1, br0 uses FID 0, and br1 uses FID 3.

c2227a39a0 nfsd: Drop BUG_ON and ignore SECLABEL on absent filesystem
On an absent filesystem (one served by another server), we need to be
able to handle requests for certain attributest (like fs_locations, so
the client can find out which server does have the filesystem), but
others we can't.

We forgot to take that into account when adding another attribute
bitmask work for the SECURITY_LABEL attribute.

There an export entry with the "refer" option can result in:

Simon Horman says:

====================
IPVS Fixes for v4.2

please consider this fix for v4.2.
For reasons that are not clear to me it is a bumper crop.

It seems to me that they are all relevant to stable.
Please let me know if you need my help to get the fixes into stable.

* ipvs: fix ipv6 route unreach panic

  This problem appears to be present since IPv6 support was added to
  IPVS in v2.6.28.

* ipvs: skb_orphan in case of forwarding

  This appears to resolve a problem resulting from a side effect of
  41063e9dd1 ("ipv4: Early TCP socket demux.") which was included in v3.6.

* ipvs: do not use random local source address for tunnels

  This appears to resolve a problem introduced by
  026ace060d ("ipvs: optimize dst usage for real server") in v3.10.

* ipvs: fix crash if scheduler is changed

  This appears to resolve a problem introduced by
  ceec4c3816 ("ipvs: convert services to rcu") in v3.10.

  Julian has provided backports of the fix:
  * [PATCHv2 3.10.81] ipvs: fix crash if scheduler is changed
    http://www.spinics.net/lists/lvs-devel/msg04008.html
  * [PATCHv2 3.12.44,3.14.45,3.18.16,4.0.6] ipvs: fix crash if scheduler is changed
    http://www.spinics.net/lists/lvs-devel/msg04007.html

  Please let me know how you would like to handle guiding these
  backports into stable.

* ipvs: fix crash with sync protocol v0 and FTP

  This appears to resolve a problem introduced by
  749c42b620 ("ipvs: reduce sync rate with time thresholds") in v3.5

0838aa7fcf netfilter: fix netns dependencies with conntrack templates
Quoting Daniel Borkmann:

"When adding connection tracking template rules to a netns, f.e. to
configure netfilter zones, the kernel will endlessly busy-loop as soon
as we try to delete the given netns in case there's at least one
template present, which is problematic i.e. if there is such bravery that
the priviledged user inside the netns is assumed untrusted.

Minimal example:

  ip netns add foo
  ip netns exec foo iptables -t raw -A PREROUTING -d 1.2.3.4 -j CT --zone 1
  ip netns del foo

What happens is that when nf_ct_iterate_cleanup() is being called from
nf_conntrack_cleanup_net_list() for a provided netns, we always end up
with a net->ct.count > 0 and thus jump back to i_see_dead_people. We
don't get a soft-lockup as we still have a schedule() point, but the
serving CPU spins on 100% from that point onwards.

Since templates are normally allocated with nf_conntrack_alloc(), we
also bump net->ct.count. The issue why they are not yet nf_ct_put() is
because the per netns .exit() handler from x_tables (which would eventually
invoke xt_CT's xt_ct_tg_destroy() that drops reference on info->ct) is
called in the dependency chain at a *later* point in time than the per
netns .exit() handler for the connection tracker.

This is clearly a chicken'n'egg problem: after the connection tracker
.exit() handler, we've teared down all the connection tracking
infrastructure already, so rightfully, xt_ct_tg_destroy() cannot be
invoked at a later point in time during the netns cleanup, as that would
lead to a use-after-free. At the same time, we cannot make x_tables depend
on the connection tracker module, so that the xt_ct_tg_destroy() would
be invoked earlier in the cleanup chain."

Daniel confirms this has to do with the order in which modules are loaded or
having compiled nf_conntrack as modules while x_tables built-in. So we have no
guarantees regarding the order in which netns callbacks are executed.

Fix this by allocating the templates through kmalloc() from the respective
SYNPROXY and CT targets, so they don't depend on the conntrack kmem cache.
Then, release then via nf_ct_tmpl_free() from destroy_conntrack(). This branch
is marked as unlikely since conntrack templates are rarely allocated and only
from the configuration plane path.

Note that templates are not kept in any list to avoid further dependencies with
nf_conntrack anymore, thus, the tmpl larval list is removed.

929423fa83 xen: release lock occasionally during ballooning
When dom0 is being ballooned balloon_process() will hold the balloon
mutex until it is finished. This will block e.g. creation of new
domains as the device backends for the new domain need some
autoballooned pages for the ring buffers.

Avoid this by releasing the balloon mutex from time to time during
ballooning. Adjust the comment above balloon_process() regarding
multiple instances of balloon_process().

Instead of open coding it, just use cond_resched().

3827ec3d8f s390: adapt entry.S to the move of thread_struct
git commit 0c8c0f03e3
"x86/fpu, sched: Dynamically allocate 'struct fpu'"
moved the thread_struct to the end of the task_struct.

This causes some of the offsets used in entry.S to overflow their
instruction operand field. To fix this  use aghi to create a
dedicated pointer for the thread_struct.

d05a76ab4d ARCv2: add knob for DIV_REV in Kconfig
Being highly configurable core ARC HS among other features might be
configured with or without DIV_REM_OPTION (hardware divider).

That option when enabled adds following instructions: div, divu, rem, remu.

By default ARC HS38 has this option enabled. So we add here possibility
to disable usage of hardware divider by compiler.

This also enables us to implement callbacks for new states of clockevent

We want to call cpu_idle_poll_ctrl() in shutdown only if we were in
oneshot or resume state earlier. Create another variable to save this
information and check that in shutdown callback.

Tests with a Sierra Wireless MC7355 have shown that 1199:9041 devices
also require the option_send_setup() code to be used on the USB
interface for the AT port to make unsolicited response codes work
correctly. Move these devices from the qcserial driver to the option
driver like it has been done for the 1199:68c0 devices in commit
d80c0d1418 ("USB: qcserial/option: make

9571b25df1 Subject: pinctrl: imx1-core: Fix debug output in .pin_config_set callback
imx1_pinconf_set assumes that the array of pins in struct
imx1_pinctrl_soc_info can be indexed by pin id to get the
pinctrl_pin_desc for a pin. This used to be correct up to commit
607af165c0 which removed some entries from the array and so made it
wrong to access the array by pin id.

The result of this bug is a wrong pin name in the output for small pin
ids and an oops for the bigger ones.

This patch is the result of a discussion that includes patches by Markus
Pargmann and Chris Ruehl.

714b1dd8f7 pinctrl: bcm2835: Clear the event latch register when disabling interrupts
It's possible to hit a race condition if interrupts are generated on a GPIO
pin when the IRQ line in question is being disabled.

If the interrupt is freed, bcm2835_gpio_irq_disable() is called which
disables the event generation sources (edge, level). If an event occurred
between the last disabling of hard IRQs and the write to the event
source registers, a bit would be set in the GPIO event detect register
(GPEDSn) which goes unacknowledged by bcm2835_gpio_irq_handler()
so Linux complains loudly.

There is no per-GPIO mask register, so when disabling GPIO interrupts
write 1 to the relevant bit in GPEDSn to clear out any stale events.

c10372e615 pinctrl: single: ensure pcs irq will not be forced threaded
The PSC IRQ is requested using request_irq() API and as result it can
be forced to be threaded IRQ in RT-Kernel if PCS_QUIRK_HAS_SHARED_IRQ
is enabled for pinctrl domain.

As result, following 'possible irq lock inversion dependency' report
can be seen:

61bb3aef92 sh-pfc: fix sparse GPIOs for R-Car SoCs
The PFC driver causes the kernel to hang on the R-Car gen2 SoC based  boards
when the CPU_ALL_PORT() macro is fixed to reflect the reality, i.e. when the
GPIO space becomes actually sparse.  This happens because the _GP_GPIO() macro
includes  an indexed initializer which causes the "holes" (array entries filled
with all 0s) between the groups  of the existing GPIOs; and the driver can't
cope with that.  There seems to  be no reason to use the indexed initializer,
so we can remove the index specifier and so avoid the "holes".

27aa2e3a3c pinctrl: abx500: remove strict mode
Commit a21763a0b1
"pinctrl: nomadik: activate strict mux mode"
put all Nomadik pin controllers to strict mode. This was
not good on the Snowball platform: the muxing of GPIOs to
different pins is done with hogs in the DTS file, and then
these GPIOs are used by offset, relying on hogs to mux the
pins. Since that means the pin controller "owns" the pins
and at the same time we have a GPIO user, this pin controller
is by definition not strict.

033ea349a7 ALSA: hda - Fix Skylake codec timeout
When the controller is powered up but the HDMI codec is powered down
on Skylake, the power well is turned off. When the codec is then
powered up again, we need to poke the codec a little extra to make
sure it wakes up. Otherwise we'll get sad "no response from codec"
messages and broken audio.

This also changes azx_runtime_resume to actually call
snd_hdac_set_codec_wakeup for Skylake (before STATETS read).
(Otherwise it would only have been called for Haswell and Broadwell,
which both do not need it, so this probably was not the author's
intention.)

0420694ddd ALSA: hda - Add headset mic support for Acer Aspire V5-573G
Acer Aspire V5 with the ALC282 codec is given the wrong value for the
0x19 PIN by the laptop's BIOS. Overriding it with the correct value
adds support for the headset microphone which would not otherwise be
visible in the system.

The fix is based on commit 7819717b11 with a similar quirk for Acer
Aspire with the ALC269 codec.

iio_device_register should be the last operation during probe. Therefor
move up interrupt setup code and while at it, change the check for invalid
values of client->irq to be smaller than zero.
Fixes: 3dd477acbd ("iio: light: Add threshold interrupt support for STK3310")

As the device_register makes the userspace interfaces of the device available
it is possible for requests to come in before the probe sequence has finished.
This can lead to unhandled interrupts and similar.

c5d0db0690 iio: mma8452: use iio event type IIO_EV_TYPE_MAG
IIO_EV_TYPE_THRESH in rising direction describes an event where the
threshold is crossed in rising direction, positive or negative values
being possible. This is not the case here.

Since the threshold is no signed value and only the magnitude is compared,
IIO_EV_TYPE_MAG is what describes the behaviour of these devices, see the
sysfs-bus-iio ABI Documentation.

41be6a0d5a iio: mcp320x: Fix NULL pointer dereference
On reading in_voltage_scale of we got an NULL pointer dereference Oops.

The reason for this is, that mcp320x_read_raw tries to access
chip_info->resolution from struct mcp320x, but chip_info is never set.

chip_info was never set since the driver was added, but there was no
acute problem, because it was not referenced.
The acute problem exists since
b12206e917
iio: adc: mcp320x. Add support for more ADCs

This patch fixes the issue by setting chip_info in mcp320x_probe.
