[PATCH] Only allocate percpu data for possible CPUs
percpu_data blindly allocates bootmem memory to store NR_CPUS instances of cpudata, instead of allocating memory only for possible cpus. This patch saves ram, allocating num_possible_cpus() (instead of NR_CPUS) instances. Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Acked-by: "David S.
