Hi all, Today's linux-next merge of the tip tree got a conflict in arch/s390/kernel/smp.c between commit 8b646bd75908 ("[S390] rework smp code") from the s390 tree and commit 5fbd036b552f ("sched: Cleanup cpu_active madness") from the tip tree. Just context changes. I fixed it up (see below) and can carry the fix as necessary. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au diff --cc arch/s390/kernel/smp.c index 64ebbcb,b0e28c4..0000000 --- a/arch/s390/kernel/smp.c +++ b/arch/s390/kernel/smp.c @@@ -714,12 -544,12 +714,6 @@@ static void __cpuinit smp_start_seconda ipi_call_lock(); set_cpu_online(smp_processor_id(), true); ipi_call_unlock(); - /* - * Wait until the cpu which brought this one up marked it - * active before enabling interrupts. - */ - while (!cpumask_test_cpu(smp_processor_id(), cpu_active_mask)) - cpu_relax(); - __ctl_clear_bit(0, 28); /* Disable lowcore protection */ - S390_lowcore.restart_psw.mask = - PSW_DEFAULT_KEY | PSW_MASK_BASE | PSW_MASK_EA | PSW_MASK_BA; - S390_lowcore.restart_psw.addr = - PSW_ADDR_AMODE | (unsigned long) psw_restart_int_handler; - __ctl_set_bit(0, 28); /* Enable lowcore protection */ local_irq_enable(); /* cpu_idle will call schedule for us */ cpu_idle();
