  Modified files:
    sys/amd64/isa        atpic.c 
    sys/i386/isa         atpic.c 
  Log:
  Explicitly use spinlock_enter/exit rather than locking the icu_lock spin
  lock in the 8259A drivers as these drivers are only used on UP systems.
  This slightly reduces the penalty of an SMP kernel (such as GENERIC) on
  a UP x86 machine.
