Date: Tue, 30 Jun 2009 12:36:20 +0100 From: "Jan Beulich" <JBeulich@...ell.com> To: "Rusty Russell" <rusty@...tcorp.com.au>, <linux-kernel@...r.kernel.org> Subject: [PATCH] fix num_..._cpus() for non-SMP After commit ae7a47e72e1a0b5e2b46d1596bc2c22942a73023, the type of num_online_cpus() & Co differs between MP and UP builds, causing e.g. uses of max()/min() to result in compilation issues.
