Actually this one's easily solvable if you base the quilt on the block
tree (just specify it to linux-next in the BASE directive and it will do
the right thing).

What I'd do is actually run two quilts: one based on vanilla and one
based on block and only add block dependent patches to the latter.  This
is like running a postmerge git tree (you can only send a pull request
for it after block goes in).
