| | | | | | | | | | | | Fix problem caused by reordering of the calls to uv_cpu_init() & uv_system_init. Originally, uv_cpu_init() was called AFTER uv_system_init. This order was recently broken as a side-effect of other patches. With this patch, initialization of cpu 0 is now done by the system_init call.

| | | | | | | | | | | | | | | Initialize a per CPU HPET MSI timer when possible. We retain the HPET timer 0 (IRQ 0) and timer 1 (IRQ 8) as is when legacy mode is being used. We setup the remaining HPET timers as per CPU MSI based timers. This per CPU timer will eliminate the need for timer broadcasting with IRQ 0 when there is non-functional LAPIC timer across CPU deep C-states. If there are more CPUs than number of available timers, CPUs that do not find any timer to use will continue using LAPIC and IRQ 0 broadcast.
