The default value for CONFIG_RCU_CPU_STALL_TIMEOUT was changed from 60
seconds to 21 seconds in 2012 in the upstream kernel. Some targets
already use 21 seconds.
This patch changes the default value in the generic configuration to 21
seconds and removes the target specific configuration options.

Based on the existing documentation [1][2], I dare anyone to demonstrate that
we need to fine-tune these RCU parameters. The (performance) breakage potential
for doing so is immense, so let's just please put down this loaded footgun.
Disable CONFIG_RCU_EXPERT and its dependent symbols. Additionally, remove the
CONFIG_RCU_EXPERT symbol from the target kconfigs which contain it.

This kmod is similar to macvlan with the difference being that the
endpoints have the same mac address.
It is useful on cloud where only one mac address allowed on port,
where macvlan not works but ipvlan would.
One use case is where multiple IPs and gateways assign on one net port

Allow for single (external-data) FIT image to hold kernel, dtb and
squashfs. In that way, the bootloader verifies the system integrity
including the rootfs, because what's the point of checking that the
hash of the kernel is correct if it won't boot in case of squashfs
being corrupted? Better allow bootloader to check everything needed
to make it at least up to failsafe mode. As a positive side effect
this change also makes the sysupgrade process on nand potentially
much easier as it is now.
In short: mkimage has a parameter '-E' which allows generating FIT
images with 'external' data rather than embedding the data into the
device-tree blob itself. In this way, the FIT structure itself remains
small and can be parsed easily (rather than having to page around
megabytes of image content). This patch makes use of that and adds
support for adding sub-images of type 'filesystem' which are used to
store the squashfs. Now U-Boot can verify the whole OS and the new
partition parsers added in the Linux kernel can detect the filesystem
sub-images, create partitions for them, and select the active rootfs
volume based on the configuration in FIT (passing configuration via
device tree could be implemented easily at a later stage).
This new FIT partition parser works for NOR flash (on top of mtdblock),
NAND flash (on top of ubiblock) as well as classic block devices
(ie. eMMC, SDcard, SATA, NVME, ...).
It could even be used to mount such FIT images via `losetup -P` on a
user PC if this patch gets included in Linux upstream one day ;)

Currently, you are not able to get statistics about IPv4 and IPv6

However, in the current state this interface is disabled as you can
read in the "902-debloat_proc.patch":
"Strip non-essential /proc functionality to reduce code size"
Tools like netstat use the snmp/6 interface to collect interface
statistics. Some prometheus exporters also mention this:

- prometheus-collectors/snmp6 (still a PR)
- collectd/snmp6 (still a PR)

In kernel commit adf82accc5f5 ("netfilter: x_tables: merge ip and
ipv6 masquerade modules") the config symbols IP_NF_TARGET_MASQUERADE
and IP6_NF_TARGET_MASQUERADE have been demoted to simple backwards-
compat options for NETFILTER_XT_TARGET_MASQUERADE.
In netfilter.mk, this has already been updated in OpenWrt commit
d1592306cc ("netfilter.mk: use CONFIG_NETFILTER_XT_TARGET_MASQUERADE"),
having us use the new config symbol.
However, enabling IP_NF_NAT or IP6_NF_NAT still makes the relevant
legacy options selectable, so we need to disable them in generic
config (and forget about them afterwards).
Since CONFIG_IP_NF_TARGET_MASQUERADE is already present there, this
just adds the missing CONFIG_IP6_NF_TARGET_MASQUERADE.
