upstream commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
reimplemented cns3xxx_pci_read_config() using pci_generic_config_read32(),
which preserved the property of only doing 32-bit reads.
It also replaced cns3xxx_pci_write_config() with pci_generic_config_write(),
so it changed writes from always being 32 bits to being the actual size,
which works just fine.
Due to:
- The documentation does not mention that only 32 bit access is allowed.
- Writes are already executed using the actual size
- Extensive testing shows that 8b, 16b and 32b reads work as intended
It makes perfectly sense to also swap 32 bit reading in favor of actual size.

Originally, cns3xxx used it's own functions for mapping, reading and writing registers.
Upstream commit 802b7c06adc7 ("ARM: cns3xxx: Convert PCI to use generic config accessors")
removed the internal PCI config write function in favor of the generic one:
cns3xxx_pci_write_config() --> pci_generic_config_write()
cns3xxx_pci_write_config() expected aligned addresses, being produced by cns3xxx_pci_map_bus()
while the generic one pci_generic_config_write() actually expects the real address
as both the function and hardware are capable of byte-aligned writes.
This currently leads to pci_generic_config_write() writing
to the wrong registers on some ocasions.
First issue seen due to this:
- driver ath9k gets loaded
- The driver wants to write value 0xA8 to register PCI_LATENCY_TIMER, located at 0x0D
- cns3xxx_pci_map_bus() aligns the address to 0x0C
- pci_generic_config_write() effectively writes 0xA8 into register 0x0C (CACHE_LINE_SIZE)
This seems to cause some slight instability when certain PCI devices are used.
Another issue example caused by this this is the PCI bus numbering,
where the primary bus is higher than the secondary, which is impossible.
Before:
00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode])
Flags: bus master, fast devsel, latency 0, IRQ 255
Bus: primary=02, secondary=01, subordinate=ff, sec-latency=0
After fix:
00:00.0 PCI bridge: Cavium, Inc. Device 3400 (rev 01) (prog-if 00 [Normal decode])
Flags: bus master, fast devsel, latency 0, IRQ 255
Bus: primary=00, secondary=01, subordinate=02, sec-latency=0
And very likely some more ..
Fix all by omitting the alignment being done in the mapping function.

Backport an additional patch from 4.16 for nftables.

Commit b7265c59ab ("kernel: backport a series of netfilter cleanup
patches to 4.14") added patch 302-netfilter-nf_tables_inet-don-t-use-
multihook-infrast.patch. That patch switches the netfilter core in the
kernel to use the new native NFPROTO_INET support. Unfortunately, the
new native NFPROTO_INET support does not exist in 4.14 and was not
backported along with this patchset. As such, nftables inet tables never
see any traffic.
As an example the following nft counter rule should increment for every
packet coming into the box, but never will:
nft add table inet foo
nft add chain inet foo bar { type filter hook input priority 0\; }
nft add rule inet foo bar counter
This commit pulls in the required backport patches to add the new
native NFPROTO_INET support, and thus restore nftables inet table
functionality.

changes after power cut data could be lost. This problem was exposed by

This is a new & warm feature that allows nesting partiitons in DT and
mixing their types (e.g. static vs. dynamic). It's very useful for
boards that have most partitions static but some of them require extra
parsing (e.g. a "firmware" partition).
It's required to successfully backport support for new devices using
that new syntax in their DT files.
Since brcm63xx has a custom alternative patch the upstream one is being
reverted for it. The plan is to make brcm63xx use the upstream
implementation.

Backport a hot off the press upstream kernel ATM fix:
Preserve value of skb->truesize when accounting to vcc
"There's a hack in pskb_expand_head() to avoid adjusting skb->truesize
for certain skbs. Ideally it would cover ATM too. It doesn't. Just
stashing the accounted value and using it in atm_raw_pop() is probably
the easiest way to cope."
The issue was exposed by upstream with:
