/* These spinlocks are used in the SMP configuration in order to implement

* 1. The up_cpu_pause() implementation on CPUn locks both g_cpu_wait[m]
* and g_cpu_paused[m]. CPUn then waits spinning on g_cpu_paused[m].
* 2. CPUm receives the interrupt it (1) unlocks g_cpu_paused[m] and
* (2) locks g_cpu_wait[m]. The first unblocks CPUn and the second
* blocks CPUm in the interrupt handler.
*
* When CPUm resumes, CPUn unlocks g_cpu_wait[m] and the interrupt handler
* on CPUm continues. CPUm must, of course, also then unlock g_cpu_wait[m]
* so that it will be ready for the next pause operation.
