Message-Id: <1269974370-24831-1-git-send-email-jason.wessel@windriver.com> Date: Tue, 30 Mar 2010 13:39:30 -0500 From: Jason Wessel <jason.wessel@...driver.com> To: Frederic Weisbecker <fweisbec@...il.com> Cc: linux-kernel@...r.kernel.org, Jason Wessel <jason.wessel@...driver.com>, Frederic Weisbecker <fweisbec@...il.com>, Ingo Molnar <mingo@...e.hu>, stable@...nel.org Subject: [PATCH] x86,kgdb: Always initialize the hw breakpoint attribute It is required to call hw_breakpoint_init() on an attr before using it in any other calls. This fixes the problem where kgdb will sometimes fail to initialize on x86_64.
