When ASLR_PIE was activated globally these drivers failed to build
because the user space LDFLAGS leaked into the kernel build process.
This was fixed in upstream Linux kernel commit ce99d0bf312d ("kbuild:
clear LDFLAGS in the top Makefile") which went into Linux 4.17. The
lantiq target is now on Linux 4.19 only and these exceptions are not
needed any more.

Linux 4.15 removes the init_timer() API. It's replaced by two functions:
- timer_setup() is used instead of init_timer() and also replaces the
timer "function" (callback) setup.
- from_timer() has to be used to obtain the use-case specific data from
a struct timer_list, which is now passed to the timer callback.
Update the timer API to be compatible with Linux 4.15+ so it compiles
with the upcoming Linux 4.19 kernel update.

This patch re-enables the reset_ppe() functionality for VR9 targets by using
the new lantiq rcu subsystem. The reset sequence in the reset_ppe() function
was taken from the ppa datapath driver of lantiq UGW 7.4.1.
Additionally it adds the required reset definitions to the vr9 dtsi file.
It also prepares the reset_ppe() function calls for the other lantiq targets.
This feature is needed to be able to switch between ltq-atm/ltq-ptm driver
in ATM/PTM Auto-Mode at runtime.

The ATM subsystem is different from the generic ethernet NICs. The ATM
subsystem requires a callback when a packet has been sent. It means a
tx skb_buff need to be used after it has sent. While the generic NIC
can fill up the TX ring and free skb_buffs if it encounter a ring buffer slot
with an already sent skbuff.
The ATM drivers need call the pop() function after it has send a
single ATM package. The ATM subsystem controls via this ways the queuing.
The ppe engine use DMA channels for read and write. Every atm_vcc has it's
own TX DMA channel and each TX DMA channel has it's own ring buffer.
The old driver had multiple issues:
- Call the subsystem callback at the beginning of tx function (ppe_send).
Didn't allowed the ATM subsystem to control the enqueued package
amount.
- Filled up the TX ring until full and fail futher
- copy or decouple the skb from all other subsystem before giving it
over to TX ring
The new tx path uses interupts.
- call the subsystem callback _after_ it was sent by hardware
- no need to copy our decouple the skb any more
- gives back control to the atm subsystem over the enqueued packages
- use an interupt for every sent atm package
Using interupts shouldn't be a problem because of the slow uplink bandwidth of
ADSL.
The speed _through_ the DSL router was always as high as it should
be, only traffic generated on the router itself were affected.
After changing to new tx path, the speed of iperf's run on the
router itself reached the same speed. The master/trunk wasn't as much
affected because of TCP optimisations (reboot-5022-gb2ea46fe236a).
The following results are taken on the remote server, which receives
the stream over the internet and the DSL line.

Renaming an atm etherbride using 'ip link' (via hotplug) is racy since the

local2.notice br2684ctl[1667]: Communicating over ATM 0.8.35, encapsulation: LLC

kern.err kernel: br2684:br2684_regvcc: tried to attach to non-existent device
local2.err br2684ctl[1667]: Could not configure interface:No such device or address
By passing the final used netdev name to br2684ctl_wrap another race
condition workaround will be enabled again.
Change the lantiq ptm driver to create a netdev with the name dsl as well.

Principal purpose is to prevent the error message

which is printed at least once per second to the serial console, if the
ptm interface is not in showtime, but a processes already sends
packages over that interface. This happens for adsl as well as vdsl
over ptm.
It's pppd which sends packages over the ptm device before in showtime.
