2018-04-25 Thread AKASHI Takahiro
On arm64, purugatory would do almosty nothing. So just invoke secondary kernel directy by jumping into its entry code. While, in this case, cpu_soft_restart() must be called with dtb address in the fifth argument, the behavior still stays compatible with kexec_load case as long as the argument is
