Remove non-UAPI Kbuild files that have become empty as a result of UAPI
disintegration. They used to have only header-y lines in them and those have
now moved to the Kbuild files in the corresponding uapi/ directories.
Possibly these should not be removed but rather have a comment inserted to say
they are intentionally left blank. This would make it easier to add generated
header lines in future without having to restore the infrastructure.
Note that at this point not all the UAPI disintegration parts have been merged,
so it is likely that more empty Kbuild files will turn up.
It is probably necessary to make the files non-empty to prevent the patch
program from automatically deleting them when it reduces them to nothing.

net/sched: add ACT_CSUM action to update packets checksums
ACT_CSUM can be called just after ACT_PEDIT in order to re-compute some
altered checksums in IPv4 and IPv6 packets. The following checksums are
supported by this patch:
- IPv4: IPv4 header, ICMP, IGMP, TCP, UDP & UDPLite
- IPv6: ICMPv6, TCP, UDP & UDPLite
It's possible to request in the same action to update different kind of
checksums, if the packets flow mix TCP, UDP and UDPLite, ...
An example of usage is done in the associated iproute2 patch.
Version 3 changes:
- remove useless goto instructions
- improve IPv6 hop options decoding
Version 2 changes:
- coding style correction
- remove useless arguments of some functions
- use stack in tcf_csum_dump()
- add tcf_csum_skb_nextlayer() to factor code

Stateless NAT is useful in controlled environments where restrictions are
placed on through traffic such that we don't need connection tracking to
correctly NAT protocol-specific data.
In particular, this is of interest when the number of flows or the number
of addresses being NATed is large, or if connection tracking information
has to be replicated and where it is not practical to do so.
Previously we had stateless NAT functionality which was integrated into
the IPv4 routing subsystem. This was a great solution as long as the NAT
worked on a subnet to subnet basis such that the number of NAT rules was
relatively small. The reason is that for SNAT the routing based system
had to perform a linear scan through the rules.
If the number of rules is large then major renovations would have take
place in the routing subsystem to make this practical.
For the time being, the least intrusive way of achieving this is to use
the u32 classifier written by Alexey Kuznetsov along with the actions
infrastructure implemented by Jamal Hadi Salim.
The following patch is an attempt at this problem by creating a new nat
action that can be invoked from u32 hash tables which would allow large
number of stateless NAT rules that can be used/updated in constant time.
The actual NAT code is mostly based on the previous stateless NAT code
written by Alexey. In future we might be able to utilise the protocol
NAT code from netfilter to improve support for other protocols.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
