Since bp is garbage whenever CONFIG_FRAME_POINTER is not\ndefined, this means all callers in principle should either always pass\n0, or be conditional on CONFIG_FRAME_POINTER.\n\nHowever, there are only really three use cases for stack tracing:\n\n(a) Trace the current task, including IRQ stack if any\n(b) Trace the current task, but skip IRQ stack\n(c) Trace some other task\n\nIn all cases, if CONFIG_FRAME_POINTER is not defined, bp should just\nbe 0. If it _is_ defined, then\n\n- in case (a) bp should be gotten directly from the CPU\u0027s register, so\n the caller should pass NULL for regs,\n\n- in case (b) the caller should should pass the IRQ registers to\n dump_trace(),\n\n- in case (c) bp should be gotten from the top of the task\u0027s stack, so\n the caller should pass NULL for regs.\n\nHence, the bp argument is not necessary because the combination of\ntask and regs is sufficient to determine an appropriate value for bp.\n\nThis patch introduces a new inline function stack_frame(task, regs)\nthat computes the desired bp. This function is then called from the\ntwo versions of dump_stack().\n\nSigned-off-by: Soren Sandmann \u003cssp@redhat.com\u003e\nAcked-by: Steven Rostedt \u003crostedt@goodmis.org\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Ingo Molnar \u003cmingo@redhat.com\u003e\nCc: H.
