So I've 7 through 12 in my branch now. (7,8 and 9 are in the #linux-next
and the 10-12 are in the #testing).

The other 1-6 you have might need to be parceled out (especially the netback
one which usually goes through David Miller). Also I have to double-check -
but did somebody review those 1-6 patches?
