Commit 1dce6264045cd23e9c07574ed0bb31c7dce9354f introduced a regression
spotted on several G94 (FDObz #85160). This device seems to expect the
vblank period to be set after setting scale instead of before.
V2: shove this in a separate function
This is a candidate bug-fix for 3.18

Commit "ltc/gf100-: fix cbc issues on certain boards" moved the setting
of the large page size bit from bar/nvc0 to fb/nvc0. GK20A uses its own
FB device and the change was thus not applied to it - fix this.

Commit ae5c6c6d "ptp: Classify ptp over ip over vlan packets" changed the
code in two drivers that matches time stamps with PTP frames, with the goal
of allowing VLAN tagged PTP packets to receive hardware time stamps.
However, that commit failed to account for the VLAN header when parsing
IPv4 packets. This patch fixes those two drivers to correctly match VLAN
tagged IPv4/UDP PTP messages with their time stamps.
This patch should also be applied to v3.17.

In case an interface has been brought down before entering S3, and then
brought up out of S3, all the initialization done during
bcmgenet_probe() by bcmgenet_mii_init() calling bcmgenet_mii_config() is
just lost since register contents are restored to their reset values.
Re-apply this configuration anytime we call bcmgenet_open() to make sure
our port multiplexer is properly configured to match the PHY interface.
Since we are now calling bcmgenet_mii_config() everytime bcmgenet_open()
is called, make sure we only print the message during initialization
time not to pollute the console.

phy_disconnect() is the only way to guarantee that we are not going to
schedule more work on the PHY state machine workqueue for that
particular PHY device.
This fixes an issue where a network interface was suspended prior to a
system suspend/resume cycle and would then be resumed as part of
mdio_bus_resume(), since the GENET interface clocks would have been
disabled, this basically resulted in bus errors to appear since we are
invoking the GENET driver adjust_link() callback.

The initial state of the device's need_restore flag should'nt depend on
the current state of the PM domain. For example it should be perfectly
valid to attach an inactive device to a powered PM domain.
The pm_genpd_dev_need_restore() API allow us to update the need_restore
flag to somewhat cope with such scenarios. Typically that should have
been done from drivers/buses ->probe() since it's those that put the
requirements on the value of the need_restore flag.
Until recently, the Exynos SOCs were the only user of the
pm_genpd_dev_need_restore() API, though invoking it from a centralized
location while adding devices to their PM domains.
Due to that Exynos now have swithed to the generic OF-based PM domain
look-up, it's no longer possible to invoke the API from a centralized
location. The reason is because devices are now added to their PM
domains during the probe sequence.
Commit "ARM: exynos: Move to generic PM domain DT bindings"
did the switch for Exynos to the generic OF-based PM domain look-up,
but it also removed the call to pm_genpd_dev_need_restore(). This
caused a regression for some of the Exynos drivers.
To handle things more properly in the generic PM domain, let's change
the default initial value of the need_restore flag to reflect that the
state is unknown. As soon as some of the runtime PM callbacks gets
invoked, update the initial value accordingly.
Moreover, since the generic PM domain is verifying that all devices
are both runtime PM enabled and suspended, using pm_runtime_suspended()
while pm_genpd_poweroff() is invoked from the scheduled work, we can be
sure of that the PM domain won't be powering off while having active
devices.
Do note that, the generic PM domain can still only know about active
devices which has been activated through invoking its runtime PM resume
callback. In other words, buses/drivers using pm_runtime_set_active()
during ->probe() will still suffer from a race condition, potentially
probing a device without having its PM domain being powered. That issue
will have to be solved using a different approach.
This a log from the boot regression for Exynos5, which is being fixed in
this patch.

Based on the reference clock, which could be 25MHz or 40MHz,
AR_RTC_DERIVED_CLK is programmed differently for AR9340 and AR9550.
But, when a chip reset is done, processing the initvals
sets the register back to the default value.
Fix this by moving the code in ath9k_hw_init_pll() to
ar9003_hw_override_ini(). Also, do this override for AR9531.

When advertised capabilities are changed with mii-tool, such as:
mii-tool -A 10baseT
the existing handler has two errors.
- An actual PHY register value is provided by mii-tool, and this
must be mapped to internal state with mii_adv_to_ethtool_adv_t().
- The PHY state machine needs to be told that autonegotiation has
again been performed. If not, the MAC will not be notified of
the new link speed and duplex, resulting in a possible config
mismatch.

RT2800 and newer hardware require padding between header and payload if
header length is not multiple of 4.
For historical reasons we also align payload to to 4 bytes boundary, but
such alignment is not needed on modern H/W.
Patch fixes skb_under_panic problems reported from time to time:
https://bugzilla.kernel.org/show_bug.cgi?id=84911
https://bugzilla.kernel.org/show_bug.cgi?id=72471
http://marc.info/?l=linux-wireless&m=139108549530402&w=2
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1087591
Panic happened because we eat 4 bytes of skb headroom on each
(re)transmission when sending frame without the payload and the header
length not being multiple of 4 (i.e. QoS header has 26 bytes). On such
case because paylad_aling=2 is bigger than header_align=0 we increase
header_align by 4 bytes. To prevent that we could change the check to:
if (payload_length && payload_align > header_align)
header_align += 4;
but not aligning payload at all is more effective and alignment is not
really needed by H/W (that has been tested on OpenWrt project for few
years now).

Because we build kernels with drivers built in for many platforms, it's
normal for the ibmpowernv driver to be loaded on systems that don't have
the appropriate hardware.
Currently the driver spams the log with:
ibmpowernv ibmpowernv.0: Opal node 'sensors' not found
ibmpowernv: Platfrom driver probe failed
But there is no error, this machine is not a powernv and doesn't have
the hardware. So change the sensors message to dev_dbg(), and only print
an error about the probe failing if it's not ENODEV.
Also fix the spelling of "Platfrom" and print the actual error value.

these offloads up to the stack only when VXLAN tunnel is set.
Failing to do so, would mislead the the networking stack to assume
that the driver can offload the internal TX checksum for GRE packets

As obj->map_and_fenceable computation has changed to only be set when
the object is bound inside the global GTT (and is suitable aligned to a
fence region) we need to accommodate those changes when the tiling is
adjusted. The easiest solution is to unbind from the global GTT if we
are currently fenceable, but will not be after the tiling change.
The bug has been exposed by

drm/i915: Force CPU relocations if not GTT mapped
which changed the handling of obj->map_and_fenceable.
Note that the alignment check is a vestige from our attempts to reduce
the alignment requirements of tiled but unfenced buffers on
gen2/3. Also, that was when unbinding from the GTT meant UC writes and
clflushing, so we went to great pains to avoid such.
That leaves the actual bug of setting map_and_fenceable to true if we're
not bound to ggtt, which violates the change introduced in the above
patch. Unbinding in that case really looks like the simplest and safest
option, we have to do it anyway.

The walk code was using a 'ro_spine' to hold it's locked btree nodes.
But this data structure is designed for the rolling lock scheme, and
as such automatically unlocks blocks that are two steps up the call
chain. This is not suitable for the simple recursive walk algorithm,
which retraces its steps.
This code is only used by the persistent array code, which in turn is
only used by dm-cache. In order to trigger it you need to have a
mapping tree that is more than 2 levels deep; which equates to 8-16
million cache blocks. For instance a 4T ssd with a very small block
size of 32k only just triggers this bug.
The fix just places the locked blocks on the stack, and stops using
the ro_spine altogether.

When doing GRO processing for UDP tunnels, we never add
SKB_GSO_UDP_TUNNEL to gso_type - only the type of the inner protocol
is added (such as SKB_GSO_TCPV4). The result is that if the packet is
later resegmented we will do GSO but not treat it as a tunnel. This
results in UDP fragmentation of the outer header instead of (i.e.) TCP
segmentation of the inner header as was originally on the wire.

Congestion Threshold
Free List Starvation Threshold needs to be larger than the SGE's Egress
Congestion Threshold or we'll end up in a mutual stall where the driver waits
for Ingress Packets to drive replacing Free List Pointers and the SGE waits for

phy_read and phy_write are not set for every phy any more sine this:

b43: don't duplicate common PHY read/write ops
b43_phy_copy() accesses phy_read and phy_write directly and will fail

read and write access.

Commit e7cd1d1eb16f ("mfd: twl4030-power: Add generic reset
configuration") enabled configuring the PM features for twl4030.
This caused poweroff command to fail on devices that have the
BCI charger on twl4030 wired, or have power wired for VBUS.
Instead of powering off, the device reboots. This is because
voltage is detected on charger or VBUS with the default bits
enabled for the power transition registers.
To fix the issue, let's just clear VBUS and CHG bits as we want
poweroff command to keep the system powered off.

All interrupts coming from MUIC were ignored because interrupt source
register was masked.
The Maxim 77693 has a "interrupt source" - a separate register and interrupts
which give information about PMIC block triggering the individual
interrupt (charger, topsys, MUIC, flash LED).
By default bootloader could initialize this register to "mask all"
value. In such case (observed on Trats2 board) MUIC interrupts won't be
generated regardless of their mask status. Regmap irq chip was unmasking
individual MUIC interrupts but the source was masked
Before introducing regmap irq chip this interrupt source was unmasked,
read and acked. Reading and acking is not necessary but unmasking is.

Interrupts coming from Maxim77693 MUIC block (MicroUSB Interface
Controller) were not handled at all because wrong regmap was used for
MUIC's regmap_irq_chip.
The MUIC component of Maxim 77693 uses different I2C address thus second
regmap is created and used by max77693 extcon driver. The registers for
MUIC interrupts are also in that block and should be handled by that
second regmap.
However the regmap irq chip for MUIC was configured with default regmap
which could not read MUIC registers.

bnx2fc_queuecommand(): when allocating a new io_req, the tgt_lock
spinlock must be locked before calling bnx2fc_cmd_alloc().
The spinlock should also be kept locked until bnx2fc_post_io_req() has
been completed.
If not, a kernel thread may call bnx2fc_process_cq_compl() that extracts
the newly allocated io_req from hba->cmd_mgr->cmds and destroys it while
it is still being used by bnx2fc_post_io_req().
