rcu: permit discontiguous cpu_possible_mask CPU numbering TREE_RCU assumes that CPU numbering is contiguous, but some users need large holes in the numbering to better map to hardware layout. This patch makes TREE_RCU (and TREE_PREEMPT_RCU) tolerate large holes in the CPU numbering. However, NR_CPUS must still be greater than the largest CPU number. Signed-off-by: Paul E.
