If you want to define some date, it should be a calendar date instead
of some kernel version based on guesswork (you cannot really predict
the kernel versions for future, just remember the 2.6.39 -> 3.0 change).

Also, you cannot expect all kernel users to know what you have been
talking about. E.g. OMAP DMA API deprecation may have been discussed
before, but I only learned it after the WARN appeared in the kernel tree.
So you should start counting from that.

Personally I don't mind if you delete OMAP3 legacy boot support already
tomorrow morning, but if you want to give ~1 year transition period it
should end somewhere in the end of 2015. Of course if there are no legacy
boot users you can do it faster.
