[PATCH] undo partial cpu_exclusive sched domain disabling The partial disabling of Dinakar's new facility to allow cpu_exclusive cpusets to define dynamic sched domains doesn't go far enough. At the suggestion of Nick Piggin and Dinakar, let us instead totally disable this facility for 2.6.13, in order to avoid problems first reported by John Hawkes (corrupt sched data structures and kernel oops). This patch removes the partial disabling code in 2.6.13-rc7, in anticipation of the next patch, which will totally disable it instead.
