timer irq setup

[Thomas Koeller <thomas@koeller.dyndns.org>]

In arch/mips/kernel/traps.c, per_cpu_trap_init() contains
code to set up the global cp0_compare_irq variable. Does
this make sense? I'd say that either the irq setup should
be moved to trap_init(), or cp0_compare_irq should be
changed to a per-cpu variable, depending on what the original
intention was.
