Alexei,

Thanks for the heads up.

Grant's version differs significantly from what I had proposed.  Which
isn't a big deal, except that I'm not familiar with why he added the
'prepare' target to dtbs dtbs_install.  It's also clear from the patch
that he is _much_ more familiar with the guts of the kernel Makefile
system than I am ;-)

This really doesn't tell us much as I'm not familiar with make-kpkg and
the assumptions it makes.  Please provide more details once you've
investigated a bit more.

On a side note: It's a bit concerning to see make-kpkg grepping the
config.  In general, one should directly test for features as config
symbols are not ABI and can change at any time.

thx,

Jason.
