Message-ID: <1345687820-5248-1-git-send-email-tiejun.chen@windriver.com> Date: Thu, 23 Aug 2012 10:10:18 +0800 From: Tiejun Chen <tiejun.chen@...driver.com> To: <benh@...nel.crashing.org> CC: <jason.wessel@...driver.com>, <linuxppc-dev@...ts.ozlabs.org>, <linux-kernel@...r.kernel.org> Subject: [v2][PATCH 1/3] kgdb,ppc: do not set kgdb_single_step on ppc The kgdb_single_step flag has the possibility to indefinitely hang the system on an SMP system. The x86 arch have the same problem, and that problem was fixed by commit 8097551d9ab9b9e3630(kgdb,x86: do not set kgdb_single_step on x86). This patch does the same behaviors as x86's patch.
