Commit 587f7a694f ("gpio: davinci: Use dev name for label and
automatic base selection") broke the GPIO support on DaVinci boards
in legacy mode by allowing gpiolib to set the GPIO base automatically.
DaVinci board files use the legacy GPIO API with hard-coded GPIO line
numbers. Use the new fields in struct davinci_gpio_platform_data to
manually set the GPIO base to 0.

We now have the option to specify the GPIO base manually for davinci,

mode for da850-evm since we can no longer request the MDIO clock GPIO.
Other boards may be broken too, which I haven't tested.
The problem is in the fact that most board files still use the legacy
GPIO API where lines are requested by numbers rather than descriptors.
While this should be fixed eventually, in order to unbreak the board
for now - provide a way to manually specify the GPIO base in platform
data.

We currently crash if usb_add_gadget_udc_release() fails, since the
udc->done is not initialized until in the remove function.
Furthermore, on module removal the udc data is accessed although
the release function is already triggered by usb_del_gadget_udc()
early in the function.
Fix by rewriting the release and remove functions, basically moving
all the cleanup into the release function, and doing the completion
only in the module removal case.
The patch fixes omap_udc module probe with a failing gadged, and also
allows the removal of omap_udc. Tested by running "modprobe omap_udc;
modprobe -r omap_udc" in a loop.

syzbot was able to trigger the WARN in cttimeout_default_get() by
passing UDPLITE as l4protocol. Alias UDPLITE to UDP, both use
same timeout values.
Furthermore, also fetch GRE timeouts. GRE is a bit more complicated,
as it still can be a module and its netns_proto_gre struct layout isn't
visible outside of the gre module. Can't move timeouts around, it
appears conntrack sysctl unregister assumes net_generic() returns
nf_proto_net, so we get crash. Expose layout of netns_proto_gre instead.
A followup nf-next patch could make gre tracker be built-in as well
if needed, its not that large.
Last, make the WARN() mention the missing protocol value in case
anything else is missing.

ip_vs_dst_event is supposed to clean up all dst used in ipvs'
destinations when a net dev is going down. But it works only
when the dst's dev is the same as the dev from the event.
Now with the same priority but late registration,
ip_vs_dst_notifier is always called later than ipv6_dev_notf
where the dst's dev is set to lo for NETDEV_DOWN event.
As the dst's dev lo is not the same as the dev from the event
in ip_vs_dst_event, ip_vs_dst_notifier doesn't actually work.
Also as these dst have to wait for dest_trash_timer to clean
them up. It would cause some non-permanent kernel warnings:
unregister_netdevice: waiting for br0 to become free. Usage count = 3
To fix it, call ip_vs_dst_notifier earlier than ipv6_dev_notf
by increasing its priority to ADDRCONF_NOTIFY_PRIORITY + 5.
Note that for ipv4 route fib_netdev_notifier doesn't set dst's
dev to lo in NETDEV_DOWN event, so this fix is only needed when
IP_VS_IPV6 is defined.

Group start/stop is controlled by the DRES and DEN bits of DSYSR0 for
the first group and DSYSR2 for the second group. On most DU instances,
this maps to the first CRTC of the group. On M3-N, however, DU2 doesn't
exist, but DSYSR2 does. There is no CRTC object there that maps to the
correct DSYSR register.
Commit 9144adc5e5 ("drm: rcar-du: Cache DSYSR value to ensure known
initial value") switched group start/stop from using group read/write
access to DSYSR to a CRTC-based API to cache the DSYSR value. While
doing so, it introduced a regression on M3-N by accessing DSYSR3 instead
of DSYSR2 to start/stop the second group.
To fix this, access the DSYSR register directly through group read/write
if the SoC is missing the first DU channel of the group. Keep using the
rcar_du_crtc_dsysr_clr_set() function otherwise, to retain the DSYSR
caching feature.

We found some bugs in the DAX conversion to XArray (and one bug which
predated the XArray conversion). There were a couple of bugs in some of
the higher-level functions, which aren't actually being called in today's
kernel, but surfaced as a result of converting existing radix tree &
IDR users over to the XArray. Some of the other changes to how the
higher-level APIs work were also motivated by converting various users;
again, they're not in use in today's kernel, so changing them has a low
probability of introducing a bug.
Dan can still trigger a bug in the DAX code with hot-offline/online,
and we're working on tracking that down.

In ip packet generation, pagedlen is initialized for each skb at the
start of the loop in __ip(6)_append_data, before label alloc_new_skb.
Depending on compiler options, code can be generated that jumps to
this label, triggering use of an an uninitialized variable.
In practice, at -O2, the generated code moves the initialization below
the label. But the code should not rely on that for correctness.

When a qdisc setup including pacing FQ is dismantled and recreated,
some TCP packets are sent earlier than instructed by TCP stack.
TCP can be fooled when ACK comes back, because the following
operation can return a negative value.
tcp_time_stamp(tp) - tp->rx_opt.rcv_tsecr;
Some paths in TCP stack were not dealing properly with this,
this patch addresses four of them.

The procedure for adding a user control element has some window opened
for race against the concurrent removal of a user element. This was
caught by syzkaller, hitting a KASAN use-after-free error.
This patch addresses the bug by wrapping the whole procedure to add a
user control element with the card->controls_rwsem, instead of only
around the increment of card->user_ctl_count.
This required a slight code refactoring, too. The function
snd_ctl_add() is split to two parts: a core function to add the
control element and a part calling it. The former is called from the
function for adding a user control element inside the controls_rwsem.
One change to be noted is that snd_ctl_notify() for adding a control
element gets called inside the controls_rwsem as well while it was
called outside the rwsem. But this should be OK, as snd_ctl_notify()
takes another (finer) rwlock instead of rwsem, and the call of
snd_ctl_notify() inside rwsem is already done in another code path.

Some spurious calls of snd_free_pages() have been overlooked and
remain in the error paths of sparc cs4231 driver code. Since
runtime->dma_area is managed by the PCM core helper, we shouldn't
release manually.
