The commit b4607572ef86 (ARM: mvebu: remove conflicting muxing on
Armada 370 DB) removes the hog pins muxing. As it is explained in the
commit log it solves a warning a boot time, but more important it also
allows using the Giga port 0 of the board.
Unfortunately in the same time the commit 4904a82a9399 (arm: mvebu:
move Armada 370/XP pinctrl node definition armada-370-xp.dtsi) was
merged and it introduced again the hog pins muxing. Because of it, the
Giga port 0 of the board is no more usable.
This commit remove again the conflicting muxing (hopefully for the
last time).

Commit 0b46b8a718c6 (clocksource: arch_timer: Fix code to use physical
timers when requested) introduces the use of physical counters in the
ARM architected timer driver. However, he arm64 kernel uses CNTVCT in
VDSO. When booting in EL2, the kernel switches to the physical timers to
make things easier for KVM but it continues to use the virtual counter
both in user and kernel. While in such scenario CNTVCT == CNTPCT (since
CNTVOFF is initialised by the kernel to 0), we want to spot firmware
bugs corrupting CNTVOFF early (which would affect CNTVCT).

After the commit ef691ff48bc8 (OMAPDSS: DT: Get source endpoint by
matching reg-id) we look for the SDI output using the port number.
However, the SDI driver doesn't set the port number, which causes the
SDI display to not initialize.
Fix this by setting the SDI port number to 1. We use a hardcoded value,
as SDI was used only on OMAP3 and it's always port number 1 there.

fb_deferred_io_fsync() returns the value of schedule_delayed_work() as
an error code, but schedule_delayed_work() does not return an error. It
returns true/false depending on whether the work was already queued.
Fix this by ignoring the return value of schedule_delayed_work().

If the probe of an fb driver has been deferred due to missing
dependencies, and the probe is later ran when a module is loaded, the
fbdev framework will try to find a logo to use.
However, the logos are __initdata, and have already been freed. This
causes sometimes page faults, if the logo memory is not mapped,
sometimes other random crashes as the logo data is invalid, and
sometimes nothing, if the fbdev decides to reject the logo (e.g. the
random value depicting the logo's height is too big).
This patch adds a late_initcall function to mark the logos as freed. In
reality the logos are freed later, and fbdev probe may be ran between
this late_initcall and the freeing of the logos. In that case we will
miss drawing the logo, even if it would be possible.

HDMI hardware parameters structs for OMAP4 and OMAP5 contained two
initializers for 'clkdco_max'. The first one was a remnant with wrong
value.
Remove the extra initializer entries.

Protocol v7 uses the middle / right button bits on clickpads to communicate
"location" information of a 3th touch (and possible 4th) touch on
clickpads.
Specifically when 3 touches are down, if one of the 3 touches is in the
left / right button area, this will get reported in the middle / right
button bits and the touchpad will still send a TWO type packet rather then
a MULTI type packet, so when this happens we must add the finger reported
in the button area to the finger count.
Likewise we must also add fingers reported this way to the finger count
when we get MULTI packets.

The v7 proto differentiates between a primary touch (with high precision)
and a secondary touch (with lower precision). Normally when 2 fingers are
down and one is lifted the still present touch becomes the primary touch,
but some traces have shown that this does not happen always.
This commit deals with this by making alps_get_mt_count() not stop at the
first empty mt slot, and if a touch is present in mt[1] and not mt[0]
moving the data to mt[0] (for input_mt_assign_slots).

versa. INPUT_MT_TRACK takes care of this for us.
NEW packets have 3 problems:
1) They do not contain middle / right button info (on non clickpads)
this can be worked around by preserving the old button state
2) They do not contain an accurate fingercount, and they are
typically send when the number of fingers changes. We cannot use
the old finger count as that may mismatch with the amount of
touch coordinates we've available in the NEW packet
3) Their x data for the second touch is inaccurate leading to
a possible jump of the x coordinate by 16 units when the first
non NEW packet comes in
Since problems 2 & 3 cannot be worked around, just ignore them.

This patch adds support for CLOCK_BOOTTIME for input event timestamp.
CLOCK_BOOTTIME includes suspend time, so it would allow aplications
to get correct time difference between two events even when system
resumes from suspend state.

IBM Trackpoints have a feature to compensate for drift by recalibrating
themselves periodically. By default, if for 0.5 seconds there is no change
in position, it's used as the new zero. This duration is too low. Often,
the calibration happens when the trackpoint is in fact being used.
IBM's Trackpoint Engineering Specifications show a configuration register
that allows changing this duration, rstdft1.
Expose it via sysfs among the other settings.

All keypad column pins used as inputs should be pulled up on the STMPE24xx,
but this is not done by the current driver. Add some logic that will do
this properly. The STMPE1601 also has a keypad controller, but explicitly
does *NOT* require you to set up any pull-ups.

This reverts commit 24a0aa212ee2dbe44360288684478d76a8e20a0a.
It's causing severe userspace breakage. Namely, all the utilities from
wireless-utils which are relying on CONFIG_WEXT (which means tools like
'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw'
utility in newer wireless-tools, which is supposed to be a replacement
for all the "deprecated" binaries, but it's far away from being
massively adopted.
Please see [1] for example of the userspace breakage this is causing.
In addition to that, Larry Finger reports [2] that this patch is also
causing ipw2200 driver being impossible to build.
To me this clearly shows that CONFIG_WEXT is far, far away from being
"deprecated enough" to be removed.

Users can request to bind to arbitrary multicast groups, so warning
when the requested group number is out of range is not appropriate.
And with the warning removed, and the 'err' variable properly given
an initial value, we can remove 'found' altogether.

Netlink families can exist in multiple namespaces, and for the most
part multicast subscriptions are per network namespace. Thus it only
makes sense to have bind/unbind notifications per network namespace.
To achieve this, pass the network namespace of a given client socket
to the bind/unbind functions.
Also do this in generic netlink, and there also make sure that any
bind for multicast groups that only exist in init_net is rejected.
This isn't really a problem if it is accepted since a client in a
different namespace will never receive any notifications from such
a group, but it can confuse the family if not rejected (it's also
possible to silently (without telling the family) accept it, but it
would also have to be ignored on unbind so families that take any
kind of action on bind/unbind won't do unnecessary work for invalid
clients like that.

The driver lacks pci_disable_device in error handling code of
ne2k_pci_init_one, so the device enabled by pci_enable_device is not
disabled when errors occur.

In __bond_release_one(), when the interface is not a slave or not a slave of
"this" master, it log error message.
The message actually should be a debug message matching what bond_enslave()
does.

netlink/genetlink cleanups & multicast improvements
I'm looking at using the multicast group functionality in a way that would
benefit from knowing when there are subscribers to avoid collecting the
required data when there aren't any. During this I noticed that the unbind
for multicast groups doesn't actually work - it's never called when sockets
are closed. Luckily, nobody actually uses the functionality.
While looking at the code trying to find why it's not called and where the
multicast listeners are actually removed, I found the potential cleanup in
patch 3. Patch 2 also has a cleanup for a generic netlink API in this area.

appropriate family.

Currently, netlink_unbind() is only called when the socket
explicitly unbinds, which limits its usefulness (luckily
there are no users of it yet anyway.)
Call netlink_unbind() also when a socket is released, so it
becomes possible to track listeners with this callback and
without also implementing a netlink notifier (and checking
netlink_has_listeners() in there.)

The code is now confusing to read - first in one function down
(netlink_remove) any group subscriptions are implicitly removed
by calling __sk_del_bind_node(), but the subscriber database is
only updated far later by calling netlink_update_listeners().
Move the latter call to just after removal from the list so it
is easier to follow the code.
This also enables moving the locking inside the kernel-socket
conditional, which improves the normal socket destruction path.

There's no point to force the caller to know about the internal
genl_sock to use inside struct net, just have them pass the network
namespace. This doesn't really change code generation since it's
an inline, but makes the caller less magic - there's never any
reason to pass another socket.

- Fix for accepting connections with old user space versions of BlueZ
- Fix for Bluetooth controllers that don't have a public address
Both of these are regressions that were introduced in 3.17, so the
appropriate Cc: stable annotations are provided.
Please let me know if there are any issues pulling. Thanks.

When connectable mode is enabled (page scan on) through some non-mgmt
method the HCI_CONNECTABLE flag will not be set. For backwards
compatibility with user space versions not using mgmt we should not
require HCI_CONNECTABLE to be set if HCI_MGMT is not set.

When controllers set the HCI_QUIRK_INVALID_BDADDR flag, it is required
by userspace to program a valid public Bluetooth device address into
the controller before it can be used.
After successful address configuration, the internal state changes and
the controller runs the complete initialization procedure. However one
small difference is that this is no longer the HCI_SETUP stage. The
HCI_SETUP stage is only valid during initial controller setup. In this
case the stack runs the initialization as part of the HCI_CONFIG stage.
The controller version information, default name and supported commands
are only stored during HCI_SETUP. While these information are static,
they are not read initially when HCI_QUIRK_INVALID_BDADDR is set. So
when running in HCI_CONFIG state, these information need to be updated
as well.
This especially impacts Bluetooth 4.1 and later controllers using
extended feature pages and second event mask page.

When we reset the device, the CSR_INT gets cleared as well
as CSR_INT_MASK. Meaning that we shouldn't get any interrupt
but, due to a hardware bug, recent devices will keep sending
interrupts. This leads to an interrupt storm while stopping
the device.
The way to fix this is to ACK all the interrupts after the
device is reset so that the value of CSR_INT will stay
0xffffffff.

On stop(), we already cleared our internal state,
and the restart_complete() callback won't be
called, so simply clear the IN_HW_RESTART flag.
Keeping the flag might result in invalid state
on the next start(), preventing the driver starting
properly.
Additionally, don't take IWL_MVM_REF_UCODE_DOWN on stop()
if hw restart was requested, as the ref was already
taken in this case.

GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.
This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.
By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.
