There are other potencial users of NMI hooks and exporting random
function pointers has never been terribly stylish. I instead suggest
to use notifiers, see <linux/notifiers.h>.
Due to the locking constraints in an NMI board_nmi_handler should then
become a raw notifier and the board_ebase_setup() function could
just go away.
