The lapic_timer_always_reliable variable really takes only two values and some arithmetic in intel_idle() related to comparing it with the target C-state's MWAIT hint value is unnecessary. Simplify the code by replacing lapic_timer_always_reliable with a bool variable lapic_timer_always_reliable and dropping the LAPIC_TIMER_ALWAYS_RELIABLE symbol along with the excess computations in intel_idle(). While at it, add a comment explaining the branch taken in intel_idle() if the LAPIC timer is only reliable in C1 and modify the related debug message in intel_idle_init() accordingly (the modification of this message in the only expected functional impact of the change made here).
