[PATCH RFC] ARM64: Add cpu hotplug for device tree parking method

2015-12-17 Thread Pratyush Anand
This patch has been implemented for CPU hotplug support for device tree spin-table based parking method. While cpu is offlined, cpu_die is called and when it is brought online cpu_boot is called. So, cpu_boot must wake secondary and release pen, otherwise dynamic cpu offline/online will not work.
