Subject: MIPS: {pm,smp}-cps: use cpu_vpe_id macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c90e49f26466d1733558b8385f4755a6ee3ddafc;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

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;
