This went into v3.1-rc6.

The keyboard path went into the tty -next tree.
The IDE one is still pending (I've just resent it).

Any fixes I still have to apply?

Updated, on top of m68k master (which is at v3.1-rc10 now).
http://git.kernel.org/?p=linux/kernel/git/geert/linux-m68k.git;a=shortlog;h=refs/heads/m68k-genirq

If noone objects, I'd like to add this to the m68k master and for-3.2 branches.
