Hi Stephen,

You did some scrubbing of the macro's to support multiple kernel
versions, but there are still some leftovers.
This code seems to have a lot of "this added in version xxx"
type comments. These are probably not a good idea to include
in the mainline kernel code.

Thanks so much for taking a look.  Sorry about that, we'll remove
all such occurrences and send out a new series of patches in a bit.

Thanks!
- Andy
