From 221e3ebf6d5f2625373573155924e39f196c5d3d Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Fri, 5 Mar 2010 13:42:41 -0800 Subject: cpumask: let num_*_cpus() function always return unsigned values Dependent on CONFIG_SMP the num_*_cpus() functions return unsigned or signed values. Let them always return unsigned values to avoid strange casts. Fixes at least one warning: kernel/kprobes.c: In function 'register_kretprobe': kernel/kprobes.c:1038: warning: comparison of distinct pointer types lacks a cast Signed-off-by: Heiko Carstens Cc: Heiko Carstens Cc: Ananth N Mavinakayanahalli Cc: Masami Hiramatsu Cc: Ingo Molnar Cc: Rusty Russell Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/cpumask.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'include/linux/cpumask.h') diff --git a/include/linux/cpumask.h b/include/linux/cpumask.h index dbcee7647d9a..bae6fe24d1f9 100644 --- a/include/linux/cpumask.h +++ b/include/linux/cpumask.h @@ -90,10 +90,10 @@ extern const struct cpumask *const cpu_active_mask; #define cpu_present(cpu) cpumask_test_cpu((cpu), cpu_present_mask) #define cpu_active(cpu) cpumask_test_cpu((cpu), cpu_active_mask) #else -#define num_online_cpus() 1 -#define num_possible_cpus() 1 -#define num_present_cpus() 1 -#define num_active_cpus() 1 +#define num_online_cpus() 1U +#define num_possible_cpus() 1U +#define num_present_cpus() 1U +#define num_active_cpus() 1U #define cpu_online(cpu) ((cpu) == 0) #define cpu_possible(cpu) ((cpu) == 0) #define cpu_present(cpu) ((cpu) == 0) -- cgit v1.2.3
