Power management software requires the kernel to save and restore CPU registers while going through suspend and resume operations triggered by kernel subsystems like CPU idle and suspend to RAM. This patch implements code that provides save and restore mechanism for the arm v8 implementation. Memory for the context is passed as parameter to both cpu_do_suspend and cpu_do_resume functions, and allows the callers to implement context allocation as they deem fit. The registers that are saved and restored correspond to the registers set actually required by the kernel to be up and running which represents a subset of v8 ISA.
