From bb61ccc7dbcbc1ed4600bef5610d99ec91fd7032 Mon Sep 17 00:00:00 2001 From: Josh Boyer Date: Tue, 5 Nov 2013 09:37:29 -0500 Subject: [PATCH] x86/cpu: Allow higher NR_CPUS values The current range for SMP configs is 2 - 512 CPUs, or a full 4096 in the case of MAXSMP. There are machines that have 1024 CPUs in them today and configuring a kernel for that means you are forced to set MAXSMP. This adds additional unnecessary overhead. While that overhead might be considered tiny for large machines, it isn't necessarily so if you are building a kernel that runs across a wide variety of machines. To cover the range of more common machines today, we allow NR_CPUS to be up to 4096 when CPUMASK_OFFSTACK is enabled.
