From d80512f87474f2dfd67ef931737659acce20fe69 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 16 Dec 2013 14:31:26 +0100 Subject: s390/smp: improve setup of possible cpu mask Since under z/VM we cannot have more than 64 cpus, make sure the cpu_possible_mask does not contain more bits. This avoids wasting memory for dynamic per-cpu allocations if CONFIG_NR_CPUS is larger than 64.
