Gregory Nutt dca77fa06a sigtimedwait: When timer expires, up_unblock_task() is called. This is okay in the single CPU case because interrupts are disable in the timer interrupt handler. But it is insufficient in the SMP case. enter_ and leave_critical_section() must be called in order to manage spinlocks correctly.

This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place.

SMP: Fix timer related issues: Round robin and sporadic scheduling were only being performed for tasks running on the CPU that processes the system timer interrupt. Similary, CPU load measurements were only be processed for running on the CPU that receives the sampling interrupt.
