   3 Subject: [PATCH] ARM: qcom: select ARM_CPU_SUSPEND for power management
   4
   5 The qcom spm driver uses cpu_resume_arm(), which is not included
   6 in the kernel in all configurations:
   7
   8 drivers/built-in.o: In function `qcom_cpu_spc':
   9 :(.text+0xbc022): undefined reference to `cpu_suspend'
  10 drivers/built-in.o: In function `qcom_cpuidle_init':
  11 :(.init.text+0x610c): undefined reference to `cpu_resume_arm'
  12
  13 This adds a 'select' Kconfig statement to ensure it's always
  14 enabled.
