WARNING: arch/i386/kernel/built-in.o(.data+0x2148): Section mismatch: reference
to .init.text: (between 'thermal_throttle_cpu_notifier' and 'mtrr_mutex')
comes because struct notifier_block thermal_throttle_cpu_notifier in
arch/i386/kernel/cpu/mcheck/therm_throt.c goes in .data section but
the notifier callback function itself has been marked __cpuinit which
becomes __init == .init.text when HOTPLUG_CPU=n. The warning is bogus
because the callback will never be called out if HOTPLUG_CPU=n in the
first place (as one can see from kernel/cpu.c, the cpu_chain itself
is __cpuinitdata :-)
So, let's mark thermal_throttle_cpu_notifier as __cpuinitdata to fix
the section mismatch warning.

[The other section mismatch mentioned in bugzilla #8679 is already fixed.]
