From 0d6ffeba7f1b98cdb1f6c9b419acb3db4f4c4477 Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Thu, 28 Jul 2016 15:48:23 -0700 Subject: [PATCH] printk: when dumping regs, show the stack, not thread_info We currently show: task: ti: task.ti: " "ti" and "task.ti" are redundant, and neither is actually what we want to show, which the the base of the thread stack. Change the display to show the stack pointer explicitly.
