[PATCH] lockdep: double the number of stack-trace entries

Miles Lane reported the "BUG: MAX_STACK_TRACE_ENTRIES too low!" message, which means that during normal use his system produced enough lockdep events so that the 128-thousand entries stack-trace array got exhausted. Double the size of the array.
