OK, that's queued up.

Got a fix for that one queued up too.

Looks like there's a fix for this one posted, will add that.

Yeah after pulling in the current mainline I see at least the above
two need to be patched.

Except for the ones that have module.h included as that already
includes export.h. At least the dmtimer.c will be moved to drivers,
and could be a loadable module so module.h is better there.

Anyways, will check these and post patches.
