[patch 2.6.19-rc2] Correct definition of handle_IPI

[Keith Owens <kaos@sgi.com>]

The declaration of handle_IPI in arch/ia64/kernel/smp.c was changed but
not the definition of this function.  Remove struct pt_regs from
handle_IPI().

The declaration of handle_IPI should really be in a header file instead
of a .c file, but which one?  Adding

  extern irqreturn_t handle_IPI(int irq, void *dev_id);

to include/asm-ia64/smp.h is the obvious place but that leads to
include hell.  Using irqreturn_t requires linux/interrupt.h which
leads to a recursive mess.  sched.h includes smp.h quit early, adding
interrupt.h to smp.h uses data from sched.h before most of sched.h is
expanded.
