First, thanks a lot for doing this work.

OK, lets try to provide a cumulative patch with a good Changelog ?

And please try a "allyesconfig" build, because it doesnt build right
now :

  CC [M]  net/decnet/dn_neigh.o
net/decnet/dn_route.c: In function 'dn_forward':
net/decnet/dn_route.c:757:31: error: 'struct dst_entry' has no member
named 'neighbour'
make[2]: *** [net/decnet/dn_route.o] Error 1
make[2]: *** Waiting for unfinished jobs....
net/decnet/dn_neigh.c: In function 'dn_long_output':
net/decnet/dn_neigh.c:230:31: error: 'struct dst_entry' has no member
named 'neighbour'
net/decnet/dn_neigh.c: In function 'dn_short_output':
net/decnet/dn_neigh.c:277:31: error: 'struct dst_entry' has no member
named 'neighbour'
net/decnet/dn_neigh.c: In function 'dn_phase3_output':
net/decnet/dn_neigh.c:321:31: error: 'struct dst_entry' has no member
named 'neighbour'
make[2]: *** [net/decnet/dn_neigh.o] Error 1
make[1]: *** [net/decnet] Error 2


So there is at least one patch missing ?

Once you believe its ok, please send a proper patch with changelog like
this :
