96cb8ae28c65 ("MIPS: Rework smt cmdline parameters"),
modpost complains when building with clang:
WARNING: modpost: vmlinux.o: section mismatch in reference: core_vpe_count (section: .text) -> smp_max_threads (section: .init.data)
This warning occurs when core_vpe_count() is not inlined, as it appears
that a non-init function is referring to an init symbol. However, this
is not a problem in practice because core_vpe_count() is only called
from __init functions, cps_smp_setup() and cps_prepare_cpus().
Resolve the warning by marking core_vpe_count() as __init, as it is only
called in an init context so it can refer to init functions and symbols
and have its memory freed on boot.
