Oops, sorry. Forgot to add a depend on i8042 per this patch in Kconfig:
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=a4c724d0723b078e4ab4670e557cda1795036a7a

This patch should fix it. After applying and using your .config I
compiled the kernel without those undefined references. Should I make a
new thread where it's submitted in the proper form? 

thanks,
Giedrius
