In b8247f095e,
"net: ip_finish_output_gso: If skb_gso_network_seglen exceeds MTU, allow segmentation for local udp tunneled skbs"
gso skbs arriving from an ingress interface that go through UDP
tunneling, are allowed to be fragmented if the resulting encapulated
segments exceed the dst mtu of the egress interface.
This aligned the behavior of gso skbs to non-gso skbs going through udp
encapsulation path.
However the non-gso vs gso anomaly is present also in the following
cases of a GRE tunnel:
- ip_gre in collect_md mode, where TUNNEL_DONT_FRAGMENT is not set
(e.g. OvS vport-gre with df_default=false)
- ip_gre in nopmtudisc mode, where IFLA_GRE_IGNORE_DF is set
In both of the above cases, the non-gso skbs get fragmented, whereas the
gso skbs (having skb_gso_network_seglen that exceeds dst mtu) get dropped,
as they don't go through the segment+fragment code path.
Fix: Setting IPSKB_FRAG_SEGS if the tunnel specified IP_DF bit is NOT set.
Tunnels that do set IP_DF, will not go to fragmentation of segments.
This preserves behavior of ip_gre in (the default) pmtudisc mode.
Fixes: b8247f095e ("net: ip_finish_output_gso: If skb_gso_network_seglen exceeds MTU, allow segmentation for local udp tunneled skbs")

If DAD fails with accept_dad set to 2, global addresses and host routes
are incorrectly left in place. Even though disable_ipv6 is set,
contrary to documentation, the addresses are not dynamically deleted
from the interface. It is only on a subsequent link down/up that these
are removed. The fix is not only to set the disable_ipv6 flag, but
also to call addrconf_ifdown(), which is the action to carry out when
disabling IPv6. This results in the addresses and routes being deleted
immediately. The DAD failure for the LL addr is determined as before
via netlink, or by the absence of the LL addr (which also previously
would have had to be checked for in case of an intervening link down
and up). As the call to addrconf_ifdown() requires an rtnl lock, the
logic to disable IPv6 when DAD fails is moved to addrconf_dad_work().
Previous behavior:
root@vm1:/# sysctl net.ipv6.conf.eth3.accept_dad=2
net.ipv6.conf.eth3.accept_dad = 2

The MIPS GIC driver has previously iterated over bits set in a bitmap
representing pending IRQs by calling find_first_bit, clearing that bit
then calling find_first_bit again until all bits are clear. If multiple
interrupts are pending then this is wasteful, as find_first_bit will
have to loop over the whole bitmap from the start. Use the
for_each_set_bit macro which performs exactly what we need here instead.
It will use find_next_bit and thus only scan over the relevant part of
the bitmap, and it makes the intent of the code more clear.

The Marvell Armada 7K/8K integrates a secondary interrupt controller
very originally named "PIC". It is connected to the main GIC via a
PPI. Amongst other things, this PIC is used for the ARM PMU.
This commit adds a simple irqchip driver for this interrupt
controller. Since this interrupt controller is not needed early at boot
time, we make the driver a proper platform driver rather than use the
IRQCHIP_DECLARE() mechanism.

This fixes a Kconfig issue with UM: when I made GPIOLIB

This in turn exposed the fact that a few GPIO drivers were
implicitly assuming OF_GPIO as their dependency but instead
depended on OF alone (the typical problem being a pointer
inside gpio_chip not existing unless OF_GPIO is selected)
and then UM would fail to compile with these drivers
instead. Then I lost patience and made any GPIO driver
depending on just OF depend on OF_GPIO instead, that is
certainly what they meant and the only thing that makes
sense anyway. GPIO with just OF but !OF_GPIO does not make

Moved the *duplicate C object description* warnings for function
declarations in the nitpicky mode. In nitpick mode, you can suppress
those warnings (e.g. ioctl) with::
nitpicky = True
nitpick_ignore = [
("c:func", "ioctl"),
]
See Sphinx documentation for the config values for ``nitpick`` and
``nitpick_ignore`` [1].
With this change all the ".. cpp:function:: int ioctl(..)" descriptions
(found in the media book) can be migrated to ".. c:function:: int
ioctl(..)", without getting any warnings. E.g.::
.. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp )
.. c:function:: int ioctl( int fd, int request, struct cec_event *argp )
The main effect, is that we get those *CPP-types* back into Sphinx's C-
namespace and we need no longer to distinguish between c/cpp references,
when we refer a function like the ioctl.

The map_offset variable is specific to the register and needs to be reset
in the loop. Otherwise, subsequent register's subpacket maps will have
their bits set at the wrong index.

The silead code is using devm_foo for everything (and does not free
any resources). Except that it is using gpiod_get instead of
devm_gpiod_get (but is not freeing the gpio_desc), change this
to use devm_gpiod_get so that the gpio will be properly released.

that it is easier to manage and the individual sections can be read
directly as plain files.
