From c90e49f26466d1733558b8385f4755a6ee3ddafc Mon Sep 17 00:00:00 2001 From: Paul Burton Date: Wed, 9 Jul 2014 12:48:21 +0100 Subject: [PATCH] MIPS: {pm,smp}-cps: use cpu_vpe_id macro When determining the VPE ID of a CPU, make use of the cpu_vpe_id macro which will return 0 in a non-MT kernel build. Most code is already doing so but a couple of places weren't. Fixing this prevents a build failure for non-MT kernels where struct cpuinfo_mips does not contain the vpe_id field: arch/mips/kernel/pm-cps.c: In function 'cps_pm_enter_state': arch/mips/kernel/pm-cps.c:153:51: error: 'struct cpuinfo_mips' has no member named 'vpe_id' vpe_cfg = &core_cfg->vpe_config[current_cpu_data.vpe_id]; arch/mips/kernel/smp-cps.c: In function 'wait_for_sibling_halt': arch/mips/kernel/smp-cps.c:363:33: error: 'struct cpuinfo_mips' has no member named 'vpe_id' unsigned vpe_id = cpu_data[cpu].vpe_id; Signed-off-by: Paul Burton Reviewed-by: Markos Chandras Signed-off-by: Ralf Baechle --- arch/mips/kernel/pm-cps.c | 2 +- arch/mips/kernel/smp-cps.c | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/mips/kernel/pm-cps.c b/arch/mips/kernel/pm-cps.c index c409a5aef8ab..06147179a175 100644 --- a/arch/mips/kernel/pm-cps.c +++ b/arch/mips/kernel/pm-cps.c @@ -154,7 +154,7 @@ int cps_pm_enter_state(enum cps_pm_state state) return -EINVAL; core_cfg = &mips_cps_core_bootcfg[core]; - vpe_cfg = &core_cfg->vpe_config[current_cpu_data.vpe_id]; + vpe_cfg = &core_cfg->vpe_config[cpu_vpe_id(¤t_cpu_data)]; vpe_cfg->pc = (unsigned long)mips_cps_pm_restore; vpe_cfg->gp = (unsigned long)current_thread_info(); vpe_cfg->sp = 0; diff --git a/arch/mips/kernel/smp-cps.c b/arch/mips/kernel/smp-cps.c index 949f2c6827a0..f9b53b4eaccb 100644 --- a/arch/mips/kernel/smp-cps.c +++ b/arch/mips/kernel/smp-cps.c @@ -360,7 +360,7 @@ void play_dead(void) static void wait_for_sibling_halt(void *ptr_cpu) { unsigned cpu = (unsigned)ptr_cpu; - unsigned vpe_id = cpu_data[cpu].vpe_id; + unsigned vpe_id = cpu_vpe_id(&cpu_data[cpu]); unsigned halted; unsigned long flags;
