   4 Subject: powerpc/smp: Section mismatch from smp_release_cpus to __initdata spinning_secondaries

   8 commit 8246aca7058f3f2c2ae503081777965cd8df7b90 upstream.
   9
  10 the smp_release_cpus is a normal funciton and called in normal environments,
  11   but it calls the __initdata spinning_secondaries.
  12   need modify spinning_secondaries to match smp_release_cpus.
  13
  14 the related warning:
  15   (the linker report boot_paca.33377, but it should be spinning_secondaries)

  19 WARNING: arch/powerpc/kernel/built-in.o(.text+0x23176): Section mismatch in reference from the function .smp_release_cpus() to the variable .init.data:boot_paca.33377
  20 The function .smp_release_cpus() references
  21 the variable __initdata boot_paca.33377.
  22 This is often because .smp_release_cpus lacks a __initdata
  23 annotation or the annotation of boot_paca.33377 is wrong.
