[PATCH] arm64: kdump: Avoid to power off nonpanic CPUs

2017-10-08 Thread Leo Yan
commit a88ce63b642c ("arm64: kexec: have own crash_smp_send_stop() for crash dump for nonpanic cores") introduces ARM64 architecture function crash_smp_send_stop() to replace the weak function, this results in the nonpanic CPUs to be hot-plugged out and CPUs are placed into low power state on ARM64
