At best you can convert the current printk to pr_info and then set the log level in your cmdline to something higher than info ! > > arc_mmu_init(); > arc_cache_init(); > > - printk(arc_extn_mumbojumbo(cpu_id, str, sizeof(str))); > - printk(arc_platform_smp_cpuinfo()); > + pr_debug("%s", arc_extn_mumbojumbo(cpu_id, str, sizeof(str))); > + pr_debug("%s", arc_platform_smp_cpuinfo()); > > arc_chk_core_config(); > } > diff --git a/arch/arc/kernel/smp.c b/arch/arc/kernel/smp.c > index f462671..d1aa917 100644 > --- a/arch/arc/kernel/smp.c > +++ b/arch/arc/kernel/smp.c > @@ -177,8 +177,8 @@ int __cpu_up(unsigned int cpu, struct task_struct *idle) > > secondary_idle_tsk = idle; > > - pr_info("Idle Task [%d] %p", cpu, idle); > - pr_info("Trying to bring up CPU%u ...\n", cpu); > + pr_debug("Idle Task [%d] %p", cpu, idle); > + pr_debug("Trying to bring up CPU%u ...\n", cpu); > > if (plat_smp_ops.cpu_kick) > plat_smp_ops.cpu_kick(cpu, > diff --git a/arch/arc/mm/cache.c b/arch/arc/mm/cache.c > index a867575..7d3e79b 100644 > --- a/arch/arc/mm/cache.c > +++ b/arch/arc/mm/cache.c > @@ -1188,7 +1188,7 @@ void __ref arc_cache_init(void) > unsigned int __maybe_unused cpu = smp_processor_id(); > char str[256]; > > - printk(arc_cache_mumbojumbo(0, str, sizeof(str))); > + pr_debug("%s", arc_cache_mumbojumbo(0, str, sizeof(str))); > > /* > * Only master CPU needs to execute rest of function: > diff --git a/arch/arc/mm/tlb.c b/arch/arc/mm/tlb.c > index d0126fd..c5e70d8 100644 > --- a/arch/arc/mm/tlb.c > +++ b/arch/arc/mm/tlb.c > @@ -814,7 +814,7 @@ void arc_mmu_init(void) > char str[256]; > struct cpuinfo_arc_mmu *mmu = &cpuinfo_arc700[smp_processor_id()].mmu; > > - printk(arc_mmu_mumbojumbo(0, str, sizeof(str))); > + pr_debug("%s", arc_mmu_mumbojumbo(0, str, sizeof(str))); > > /* > * Can't be done in processor.h due to header include depenedencies >
