This fixes spurious boot-errors with some ath79 MIPS 74Kc boards such
as the AC Lite as well as Archer C7 v2.
The missing barrier leads to the icache flush being executed before the
dcache writeback, which results in the CPU executing the dummy infinite
loop in tlbmiss_handler_setup_pgd.
Applying this patch from upstream ensures the dcache is written back
before flushing the icache.

This backports the third version [1], which is awaiting upstream merge. It
adds support for watchdog max6370, which is connected via GPIO. It
is useful primarily for P2020 RDB and Turris 1.x routers, which are
not yet supported.

"842" is a compression scheme and this is the software implementation
which is too slow to really use beyond a proof of concept. It can be
selected in ZRAM, ZSWAP, or `fs/pstore`, and is here for completeness.
In general you need a Power8 or better with 842-in-hardware for it to
be fast, but other 842-accelerators are emerging.

Backport patch from kernel 5.14.
Treat only the highest, not the lowest, IPv4 address within a local
subnet as a broadcast address, as subnets do not need two different
broadcast addresses and networking documentation consistently prefers
the highest address as broadcast.
This patch was merged in upstream net-next tree in May 2021 at
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?id=94c821c74bf5
This eventually frees up one address per subnet. It matches behavior
suggested in our Internet-Draft, and also the default behavior of OpenBSD
and FreeBSD.
