Use task_stack_page instead of p->stack to get stack. Follow the coding convention style. Also for init_stack, the same with other archs. Signed-off-by: Guo Ren <ren_guo@c-sky.com>

/**
* struct klp_ops - structure for tracking registered ftrace ops structs
*
* A single ftrace_ops is shared between all enabled replacement functions
* (klp_func structs) which have the same old_addr. This allows the switch
* between function versions to happen instantaneously by updating the klp_ops
* struct's func_stack list. The winner is the klp_func at the top of the
* func_stack (front of the list).
*
* @node: node for the global klp_ops list
* @func_stack: list head for the stack of klp_func's (active func is on top)
* @fops: registered ftrace ops struct
