This patch introduce support for IPHC stateful address compression. It
will offer the context table via one debugfs entry.
This debugfs has and directory for each cid entry for the context table.
Inside each cid directory there exists the following files:
- "active": If the entry is added or deleted. The context table is
original a list implementation, this flag will indicate if the
context is part of list or not.
- "prefix": The ipv6 prefix.
- "prefix_length": The prefix length for the prefix.
- "compression": The compression flag according RFC6775.
This part should be moved into sysfs after some testing time.
Also the debugfs entry contains a "show" file which is a pretty-printout
for the current context table information.

Due to HW design, some of the memories are wide-bus and access to those
needs to be sequentialized on a per-HW-block level; Read/write to a
given HW-block might break other read/write to wide-bus memory done at
~same time.
Status blocks initialization in CAU is done into such a wide-bus memory.
This moves the initialization into using DMAE which is guaranteed to be
safe to use on such memories.

The dm9000 driver doesn't work in at least one device-tree
configuration, spitting an error message on irq resource :
[ 1.062495] dm9000 8000000.ethernet: insufficient resources
[ 1.068439] dm9000 8000000.ethernet: not found (-2).
[ 1.073451] dm9000: probe of 8000000.ethernet failed with error -2
The reason behind is that the interrupt might be provided by a gpio
controller, not probed when dm9000 is probed, and needing the probe
deferral mechanism to apply.
Currently, the interrupt is directly taken from resources. This patch
changes this to use the more generic platform_get_irq(), which handles
the deferral.
Moreover, since commit Fixes: 7085a7401b ("drivers: platform: parse
IRQ flags from resources"), the interrupt trigger flags are honored in
platform_get_irq(), so remove the needless code in dm9000.

BPF updates
This set contains various updates for eBPF, i.e. the addition of a
generic csum helper function and other misc bits that mostly improve
existing helpers and ease programming with eBPF on cls_bpf. For more
details, please see individual patches.
Set is rebased on top of http://patchwork.ozlabs.org/patch/584465/.

While debugging with bpf_jit_disasm I noticed emissions of 'mov %eax,%eax',
and found that this comes from BPF_RET | BPF_A translations from classic
BPF. Emitting this is unnecessary as BPF_REG_A is mapped into BPF_REG_0
already, therefore only emit a mov when immediates are used as return value.
