linux-stable/include/asm-ia64/irq.h
Al Viro e9ed7e722e take declarations of enable_irq() et.al. to linux/interrupt.h
Now that the last inlined instances are gone, all that is left to do
is turning disable_irq_nosync on arm26 and m68k from defines to aliases
and we are all set - we can make these externs in linux/interrupt.h
uncoditional and kill remaining instances in asm/irq.h
