From: Greg Kroah-Hartman

3.4-stable review patch. If anyone has any objections, please let me know.

------------------

From: Chen Gang <gang.chen@xxxxxxxxxxx>

commit 8246aca7058f3f2c2ae503081777965cd8df7b90 upstream.

the smp_release_cpus is a normal funciton and called in normal environments,
but it calls the __initdata spinning_secondaries.
need modify spinning_secondaries to match smp_release_cpus.

the related warning:
(the linker report boot_paca.33377, but it should be spinning_secondaries)

-----------------------------------------------------------------------------

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
The function .smp_release_cpus() references
the variable __initdata boot_paca.33377.
This is often because .smp_release_cpus lacks a __initdata
annotation or the annotation of boot_paca.33377 is wrong.
