Kernel comment style would be:

/*

 * THREAD_INFO_IN_TASK, but we define that unconditionally.
 */

THREAD_INFO_IN_TASK is always defined for riscv, so no need for this
ifdef.

Please don't cast structs around.  This should be something like

#define raw_smp_processor_id() \
	(container_of(get_current(), struct task_struct, thread_info)->cpu)
