clock

sched/clock: Correct calculation for the case of Tickless mode with a 32-bit timer. In that case, the calculation was returning millisecond accuracy. That is not good when the timer accuracy is < 1 msec.

signal

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.

Most interrupt handling logic interacts with tasks via standard mechanism such as sem_post, sigqueue, mq_send, etc. This all call enter_critical_section and are assumed to be safe in the SMP case.

wqueue

Signal sent from work_signal() may interrupt the low priority worker thread that is already running. For example, the worker thread that is waiting for a semaphore could be woken up by the signal and break any synchronization assumption as a result. It also does not make any sense to send signal if it is already running and busy. This commit fixes it.

pthread cleanup stack: Replace critical section with sched_lock/unlock(). The cleanup stack modification only needs to have the TCB stationary. The stack is never modified from interrupt level logic
