[PATCH v16 01/18] tracing: Use arch_ftrace_regs() for ftrace_regs_*() macros

[Masami Hiramatsu (Google)]

From: Masami Hiramatsu (Google) <mhiramat@xxxxxxxxxx>

Since the arch_ftrace_get_regs(fregs) is only valid when the
FL_SAVE_REGS is set, we need to use `&arch_ftrace_regs()->regs` for
ftrace_regs_*() APIs because those APIs are for ftrace_regs, not
complete pt_regs.
