Yes. We already do the patch to fix the warning yesterday after get the information from Fengguang's "0-DAY kernel build testing". But do not refresh linux-next so quickly.

Wysocki Cc: linux-next@xxxxxxxxxxxxxxx; linux-kernel@xxxxxxxxxxxxxxx; Song, Youquan; Rik van Riel Subject: linux-next: build failure after merge of the final tree (pm tree related) Hi all, After merging the final tree, today's linux-next build (powerpc allnoconfig) failed like this: In file included from arch/powerpc/kernel/idle.c:27:0: include/linux/tick.h: In function 'menu_hrtimer_cancel': include/linux/tick.h:148:48: error: 'return' with a value, in function returning void [-Werror] Several of these :-( Caused by commit 25d77b76d7ae ("cpuidle: Quickly notice prediction failure for repeat mode") from the pm tree. This build has CONFIG_CPU_IDLE_GOV_MENU turned off. For changes that are obviously affected by CONFIG options, please test build with the CONFIG option on and off. I have applied the following patch for today: From: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> Date: Wed, 24 Oct 2012 14:40:47 +1100 Subject: [PATCH] cpuidle: fix up but return type for inline function Fixes this error when CONFIG_CPU_IDLE_GOV_MENU is not enabled: In file included from arch/powerpc/kernel/idle.c:27:0: include/linux/tick.h: In function 'menu_hrtimer_cancel': include/linux/tick.h:148:48: error: 'return' with a value, in function returning void [-Werror] Signed-off-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx> --- include/linux/tick.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/tick.h b/include/linux/tick.h index 8867424..40d123e 100644 --- a/include/linux/tick.h +++ b/include/linux/tick.h @@ -145,7 +145,7 @@ static inline u64 get_cpu_iowait_time_us(int cpu, u64 *unused) { return -1; } # ifdef CONFIG_CPU_IDLE_GOV_MENU extern void menu_hrtimer_cancel(void); # else -static inline void menu_hrtimer_cancel(void) { return -1; } +static inline void menu_hrtimer_cancel(void) { } # endif /* CONFIG_CPU_IDLE_GOV_MENU */ #endif -- 1.7.10.280.gaa39 -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
