[dpdk-dev] [PATCH v16 05/11] eal: add monitor wakeup function

[Ananyev, Konstantin]

> Now that we have everything in a C file, we can store the information
> about our sleep, and have a native mechanism to wake up the sleeping
> core. This mechanism would however only wake up a core that's sleeping
> while monitoring - waking up from `rte_power_pause` won't work.
