* When a device with hundreds of apps is booted up, hundreds of apps will spawn their BOOT_COMPLETED receivers which start up their background initialization services. Since only one core is allowed for these processes, the time for all these services to complete is extremely long. * To improve this, allow three cores for background processes, keeping the fourth for idle wakeups. This ends up producing a better thermal profile for the device as well, since the small cores are not the aggressor on this SoC. Change-Id: I98bbf8bf565bd77066ff7726014e6fa5730a4e09
