ia64: Make sure interrupts enabled when we "safe_halt()" In commit d166991234347215dc23fc9dc15a63a83a1a54e1 idle: Implement generic idle function Thomas Gleixner cleaned up many things but perturbed some fragile code that was keeping ia64 alive. So we started seeing: WARNING: at kernel/cpu/idle.c:94 cpu_idle_loop+0x360/0x380() and other unpleasantness like system hangs during boot. We really shouldn't ever halt with interrupts disabled.
