mips/octeon/smp: Convert to hotplug state machine Install the callbacks via the state machine. [ tglx: Renamed the state to MIPS_SOC_PREPARE so it can be reused by other SOCs ] Signed-off-by: Sebastian Andrzej Siewior <bige...@linutronix.de> Acked-by: Ralf Baechle <r...@linux-mips.org> Cc: linux-m...@linux-mips.org Cc: Peter Zijlstra <pet...@infradead.org> Cc: r...@linutronix.de Link: http://lkml.kernel.org/r/20160906170457.32393-16-bige...@linutronix.de Signed-off-by: Thomas Gleixner <t...@linutronix.de> --- arch/mips/cavium-octeon/smp.c | 24 +++--------------------- include/linux/cpuhotplug.h | 1 + 2 files changed, 4 insertions(+), 21 deletions(-) diff --git a/arch/mips/cavium-octeon/smp.c b/arch/mips/cavium-octeon/smp.c index 4d457d60..256fe6f 100644 --- a/arch/mips/cavium-octeon/smp.c +++ b/arch/mips/cavium-octeon/smp.c @@ -380,29 +380,11 @@ static int octeon_update_boot_vector(unsigned int cpu) return 0; } -static int octeon_cpu_callback(struct notifier_block *nfb, - unsigned long action, void *hcpu) -{ - unsigned int cpu = (unsigned long)hcpu; - - switch (action & ~CPU_TASKS_FROZEN) { - case CPU_UP_PREPARE: - octeon_update_boot_vector(cpu); - break; - case CPU_ONLINE: - pr_info("Cpu %d online\n", cpu); - break; - case CPU_DEAD: - break; - } - - return NOTIFY_OK; -} - static int register_cavium_notifier(void) { - hotcpu_notifier(octeon_cpu_callback, 0); - return 0; + return cpuhp_setup_state_nocalls(CPUHP_MIPS_SOC_PREPARE, + "mips/cavium:prepare", + octeon_update_boot_vector, NULL); } late_initcall(register_cavium_notifier); diff --git a/include/linux/cpuhotplug.h b/include/linux/cpuhotplug.h index bb6231d..8f8a48b 100644 --- a/include/linux/cpuhotplug.h +++ b/include/linux/cpuhotplug.h @@ -44,6 +44,7 @@ enum cpuhp_state { CPUHP_SH_SH3X_PREPARE, CPUHP_TIMERS_DEAD, CPUHP_NOTF_ERR_INJ_PREPARE, + CPUHP_MIPS_SOC_PREPARE, CPUHP_BRINGUP_CPU, CPUHP_AP_IDLE_DEAD, CPUHP_AP_OFFLINE,
