From: Ben Dooks <ben.dooks@xxxxxxxxxx> commit e4aa991c05aedc3ead92d1352af86db74090dc3c upstream. Running sparse shows cpu_ops_spinwait.c is missing two definitions found in head.h, so include it to stop the following warnings: arch/riscv/kernel/cpu_ops_spinwait.c:15:6: warning: symbol '__cpu_spinwait_stack_pointer' was not declared. Should it be static? arch/riscv/kernel/cpu_ops_spinwait.c:16:6: warning: symbol '__cpu_spinwait_task_pointer' was not declared. Should it be static?
