[PATCH] x86,APIC: Fix false positive section mismatch in numaq_32.c

[Rakib Mullick]

 Impact: Fix false positive warning.

The variable apic_numaq placed in noninit section references the
function wakeup_secondary_cpu_via_nmi(), which is in __cpuinit
section. Thus causes a section mismatch warning. To avoid such
mismatch we mark apic_numaq as __refdata.

 We were warned by following warning:

WARNING: arch/x86/kernel/built-in.o(.data+0x932c): Section mismatch in
reference from the variable apic_numaq to the function
.cpuinit.text:wakeup_secondary_cpu_via_nmi()
The variable apic_numaq references
the function __cpuinit wakeup_secondary_cpu_via_nmi()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
