From 7523c4dd9923cab748dad9b79d0165e118e3d03b Mon Sep 17 00:00:00 2001 From: OGAWA Hirofumi Date: Thu, 4 Jan 2007 01:21:28 +0900 Subject: [PATCH] [PATCH] x86_64: Fix dump_trace() If caller passed the tsk, we should use it to validate a stack ptr. Otherwise, sysrq-t and other debugging stuff doesn't work.
