* Per the "SMC calling convention specification", the 64-bit calling
* convention can only be used when the client is 64-bit, otherwise
* system will encounter the undefined behaviour.
* When running on 32bit kernel, SCM call with convention
* SMC_CONVENTION_ARM_64 is causing the system crash. To avoid that
* use SMC_CONVENTION_ARM_64 for 64bit kernel and SMC_CONVENTION_ARM_32
* for 32bit kernel.
