Hi,
commit 0ce6966b "watchdog: update watchdog_tresh properly" breaks
build on non-SMP systems (more specifically: on systems where
CONFIG_USE_GENERIC_SMP_HELPERS is not set):
linux-next/kernel/watchdog.c: In function 'update_timers':
linux-next/kernel/watchdog.c:522:2: error: implicit declaration of function
'__smp_call_function_single' [-Werror=implicit-function-declaration]
I guess the offending code should be guarded by an
'#ifdef CONFIG_USE_GENERIC_SMP_HELPERS'
like in kernel/softirq.c:
#ifdef CONFIG_USE_GENERIC_SMP_HELPERS
[...]
static int __try_remote_softirq(struct call_single_data *cp, int cpu, int
softirq)
{
if (cpu_online(cpu)) {
cp->func = remote_softirq_receive;
cp->info = &softirq;
cp->flags = 0;
__smp_call_function_single(cpu, cp, 0);
return 0;
}
return 1;
}
#else /* CONFIG_USE_GENERIC_SMP_HELPERS */
static int __try_remote_softirq(struct call_single_data *cp, int cpu, int
softirq)
{
return 1;
}
#endif
