7012 /*
7013 * Some archs only support passing ip and parent_ip. Even though
7014 * the list function ignores the op parameter, we do not want any
7015 * C side effects, where a function is called without the caller
7016 * sending a third parameter.
7017 * Archs are to support both the regs and ftrace_ops at the same time.
7018 * If they support ftrace_ops, it is assumed they support regs.
7019 * If call backs want to use regs, they must either check for regs
7020 * being NULL, or CONFIG_DYNAMIC_FTRACE_WITH_REGS.
7021 * Note, CONFIG_DYNAMIC_FTRACE_WITH_REGS expects a full regs to be saved.
7022 * An architecture can pass partial regs with ftrace_ops and still
7023 * set the ARCH_SUPPORTS_FTRACE_OPS.
7024 *
7025 * In vmlinux.lds.h, ftrace_ops_list_func() is defined to be
7026 * arch_ftrace_ops_list_func.
