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.

Rusty - what's going on here? Please do not change APIs like that, 
which cause code to crash. Either do a compatible API change, or 
change it over in a way that causes clear build failures, not crashes.

ah, i see it from Rusty's other reply that there's going to be another 
version of this. Good :-)

	Ingo
