c7371cd1ee ar71xx: add definitions for RouterBOARD hardware option bits
Add bit definitions for the 'hardware options' tag which is used in
the MikroTik devices' hardware configurations. These values can be
used in board setup codes, to do different initialization sequences.
The values were obtained from the RouterOS 6.41-rc38 patches.

Additionally, introduce two helper functions what make the processing
of the hardware options easy.

5bdbc10b1b uqmi: silence error on pin verification
If a device only supports the 2nd verification method (uim),
the first method will fail as expected reporting an error:

"Command not supported"

Silence both separate methods and only report an error regarding
pin verification if both fail.

666e9cf222 kernel: add IEEE-1284 parallel port support
The kmod-lp package included both lp.ko and ppdev.ko, but ECP device
drivers may or may not require lp NOT to be loaded, needing only ppdev.
Additionally, There were no packages for any parport interface modules,
such as uss720 or parport_pc, provided here. It has not been otherwise
possible to use PC-style parport hardware for kmod-lp.

02050f7e7d kernel/4.{4, 9}: add manufacturer ID for Winbond NANDs
Some MikroTik devices are using a Winbond NAND flash. Linux treats
it as an unknown NAND before version 4.11:

  nand: device found, Manufacturer ID: 0xef, Chip ID: 0xf1
  nand: Unknown NAND 128MiB 3,3V 8-bit
  nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64

Backport a patch from 4.11 to show the manufacturer correctly:

  nand: device found, Manufacturer ID: 0xef, Chip ID: 0xf1
  nand: Winbond NAND 128MiB 3,3V 8-bit
  nand: 128 MiB, SLC, erase size: 128 KiB, page size: 2048, OOB size: 64

a3198061f8 dnsmasq: backport dnssec security fix
CVE-2017-15107

An interesting problem has turned up in DNSSEC validation. It turns out
that NSEC records expanded from wildcards are allowed, so a domain can
include an NSEC record for *.example.org and an actual query reply could
expand that to anything in example.org  and still have it signed by the
signature for the wildcard. So, for example

!.example.org NSEC zz.example.org

is fine.

The problem is that most implementers (your author included, but also
the Google public DNS people, powerdns and Unbound) then took that
record to prove the nothing exists between !.example.org and
zz.example.org, whereas in fact it only provides that proof between
*.example.org and zz.example.org.

This gives an attacker a way to prove that anything between
!.example.org and *.example.org doesn't exists, when it may well do so.

42b47f1b40 ipq806x: overhaul AVM FRITZ!box 4040 device-tree file
This patch aligns the device-tree file with the latest
guidelines.
 - No longer include qcom-ipq4019-ap.dk01.1.dtsi. This
   file is only partially upstream and therefore subjected
   to changes that might not be compatible with the board.

   As a result, the definitions from the file have been
   copied into this dts.

 - exclusively use decimal GPIO addresses.

 - reorganize the reserved-memory layout to waste less
   memory. There's no point in keeping the u-boot loader
   around. This should also make it possible    to create
   an image that will boot with the original EVA/ADAM2 loader
   without needing to install the modified u-boot loader.
   And finally mark the "tz-apps" as reusable.
   There isn't a way to  upload apps to the trust-zone in OpenWrt
   yet. But it might see some use in the future as a "secure"
   key-store/TPM.

 - sort the first-level nodes alphabetically.
 - sort nodes with an address by the address.

This is triggered by calling eth_schedule_poll(sw) after the IRQ has
been re-enabled.

Rework the network code to only enable IRQ's again if NAPI agrees it's
safe to do so.

Also only re-enable IRQ *after* cleaning up the RX ring and re-enabling
DMA, which otherwise resulted in ugly warnings regarding dirty page
fragments.
These popped up nearly immediately when building the kernel with O2 iso
Os.

--> Note that this change fixes stability issues, at the cost of ~8%
throughput performance.

While at it, also change the iface name being used in warning prints,
making it more obvious: "switch%d" --> "cns3xxx_eth"

The changes have been tested on 4 boards, each moving ~30TB of data
