Date: Thu, 10 Jul 2008 16:07:57 -0500 (CDT) From: Milton Miller <miltonm@....com> To: Ingo Molnar <mingo@...hat.com>, Rusty Russell <rusty@...tcorp.com.au> Cc: linuxppc-dev@...abs.org, linux-kernel@...r.kernel.org, linux-next@...r.kernel.org Subject: [PATCH -next-20080709] fixup stop_machine use cpu mask vs ftrace Hi Rusty, Ingo. Rusty's patch [PATCH 3/3] stop_machine: use cpu mask rather than magic numbers didn't find kernel/trace/ftrace.c in -next, causing an immediate almost NULL pointer dereference in ftrace_dynamic_init.
