Why does "libertas: exclude non-used code when PROC_DEBUG is not set" contain DMA/EHCI changes?

[Holger Schurig]

When you look at this patch at

http://git.infradead.org/?p=libertas-2.6.git;a=commitdiff;h=79d9d41fbbd1fc6e799e9993c04b4bcd8eaea6cc

you see that it contains "NO_DMA_ZONE" and some EHCI driver 
changes. But my original patch

http://git.infradead.org/?p=users/schurig/libertas-cleanups-2.6.git;a=commitdiff;h=98ef505f648346e70dd0c3e80e251389a5b20180

doesn't have this.
