The cause is spi_gpio_setup() did not check if the spi-gpio has
chipselect pins before setting their direction and results in derefing
an invalid pointer.
The bug is spotted in kernel 4.19.72 and does not occur in 4.14.
There is a similar fix upstream in kernel 5.2 in commit 249e2632dcd0
("spi: gpio: Don't request CS GPIO in DT use-case").

Move the IRQ fix from generic to ar71xx specific.
Other targets like ath79 have specific pathes to delete this code.
This resulted in a build failure on ath79
While at it, wipe the 4.19 version, as ar71xx will never reach this.

If both interrupts are set in the current implementation
only the 1st will be handled and the 2nd will be skipped
due to the "if else" condition.
Fix this by using the same approach as done for QCA955x
just below it.

The net pointer in struct xt_tgdtor_param is not explicitly
initialized therefore is still NULL when dereferencing it.
So we have to find a way to pass the correct net pointer to
ipt_destroy_target().
The best way I find is just saving the net pointer inside the per
netns struct tcf_idrinfo, which could make this patch smaller.

This adds support for uImage used by OpenWrt kernel loader.
The parser searches for uImage header at flash eraseblock boundary
and it might attempt to split any firmware with loader, therefore
this entry doesn't have MTD_PARSER_TYPE_FIRMWARE so that this parser
is only used when explicitly defined in dts.

This parser's matching function appears to be too generic as it matches
e.g. Buffalo WZR-HP-G300NH. That results in incorrect parts parsing.
Luckily this parser is needed by Fon FON2601 only which uses DT-based
ramips target. It means we can depend on mtd subsystem matching of
"fonfxc,uimage" string.
That said triggering this parser based on the "firmware" (or whatever
MTD_SPLIT_FIRMWARE_NAME is) partiiton name is not needed. It can be
dropped which will automatically fix the Buffalo WZR-HP-G300NH case.

This reverts commit e92a14709d.
mtdsplit_uimage_parse_fonfxc() gets called in two situations:
1) It was /requested/ from DT using "fonfxc,uimage" compatible string
2) It was called by parsing code after finding "firmware"
(MTD_SPLIT_FIRMWARE_NAME) due to the parser's type
Code added in the /fix/ commit basically just disabled the second case.
If that's the real goal it could be achieved by simply dropping type
MTD_PARSER_TYPE_FIRMWARE. It may however require another solution as
it's possible that some non-DT target actually needs fonfxc uImage
parsing.

We cannot distinguish between fonfxc uImage and generic uImage because
fonfxc uImage header is almost same as generic uImage, except padding
length after image name.
The fonfxc uImage parser is available when specifying directly with DT
compatible property. So this patch adds check if the partition DT node
is compatible with the parser.

[commit light touches and removed C code comment]
Signed-off-by: Petr Štetiar <ynezz@true.cz>
savedscp is a method of storing the DSCP of an ip packet into conntrack
mark. In combination with a suitable tc filter action (conndscp but may
end up being integrated into connmark) DSCP values are able to be stored
on egress and restored on ingress across links that otherwise alter or
bleach DSCP.
This is useful for qdiscs such as CAKE which are able to shape according
to policies based on DSCP.
Ingress classification is traditionally a challenging task since
iptables rules haven't yet run and tc filter/eBPF programs are pre-NAT
lookups, hence are unable to see internal IPv4 addresses as used on the
typical home masquerading gateway.
The ingress problem is solved by the tc filter, but the tc people didn't
like the idea of tc setting conntrack mark values, though they are ok
with reading conntrack values and hence restoring DSCP from conntrack
marks.
x_tables CONNMARK with the new savedscp action solves the problem of
storing the DSCP to the conntrack mark.
It accepts 2 parameters. The mark is a 32bit value with usually one 1
bit set. This bit is set when savedscp saves the DSCP to the mark.
This is useful to implement a 'one shot'
iptables based classification where the 'complicated' iptables rules are
only run once to classify the connection on initial (egress) packet and
subsequent packets are all marked/restored with the same DSCP. A mark
of zero disables the setting of a status bit/s.
The mask is a 32bit value of at least 6 contiguous bits and represents
the area where the DSCP will be stored.
e.g.
iptables -A QOS_MARK_eth0 -t mangle -j CONNMARK --savedscp-mark 0xfc000000/0x01000000
Would store the DSCP in the top 6 bits of the 32bit mark field, and use
the LSB of the top byte as the 'DSCP has been stored' marker.

to the wireless subsystem up to Linux 5.2-rc7.
* The removed patches are applied upstream
* b43 now uses kmod-lib-cordic
* Update the nl80211.h file in iw to match backports version.
* Remove the two backports from kernel 4.9, they were needed for mt76,
but that can use the version from backports now, otherwise they
