Date: Thu, 04 Jan 2007 01:21:28 +0900 From: OGAWA Hirofumi <hirofumi@...l.parknet.co.jp> To: Linus Torvalds <torvalds@...l.org>, Andrew Morton <akpm@...l.org> Cc: linux-kernel@...r.kernel.org Subject: [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.
