Hi Andrew, Today's linux-next merge of the akpm-current tree got a conflict in kernel/smp.c between commit f44310b98ddb ("smp: Fix SMP function call empty cpu mask race") from Linus' tree and commit "smp: make smp_call_function_many() use logic similar to smp_call_function_single()" from the akpm-current tree. I fixed it up (I think - see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc kernel/smp.c index 69f38bd,bb92c52..0000000 --- a/kernel/smp.c +++ b/kernel/smp.c @@@ -57,9 -47,11 +47,15 @@@ hotplug_cfd(struct notifier_block *nfb if (!zalloc_cpumask_var_node(&cfd->cpumask, GFP_KERNEL, cpu_to_node(cpu))) return notifier_from_errno(-ENOMEM); + if (!zalloc_cpumask_var_node(&cfd->cpumask_ipi, GFP_KERNEL, + cpu_to_node(cpu))) + return notifier_from_errno(-ENOMEM); + cfd->csd = alloc_percpu(struct call_single_data); + if (!cfd->csd) { ++ free_cpumask_var(cfd->cpumask_ipi); + free_cpumask_var(cfd->cpumask); + return notifier_from_errno(-ENOMEM); + } break; #ifdef CONFIG_HOTPLUG_CPU @@@ -69,7 -61,7 +65,8 @@@ case CPU_DEAD: case CPU_DEAD_FROZEN: free_cpumask_var(cfd->cpumask); + free_cpumask_var(cfd->cpumask_ipi); + free_percpu(cfd->csd); break; #endif };
