This looks great, all applied.  Please make the fixups recommended
to you in the feedback as followon patches.

Also, I added the following cure after your patch series:

net: compat: No need to define IFHWADDRLEN and IFNAMSIZ twice.

It's defined colloqually in linux/if.h and linux/compat.h
includes that.

Thanks! Two patches follow.

Any opinion on how to proceed with the ATM stuff? From my
point of view, I'm fine with having moved it out of fs/compat_ioctl.c,
but it's still a bit silly to have two half-complete implementations.

I haven't looked at that stuff yes, you can be sure it's in
my queue :-)
