[PATCH] x86: Fix false positive section mismatch in es7000_32.c

[Rakib Mullick <rakib.mullick@gmail.com>]

 Impact: Fix false positive warning

The variable apic_es7000_cluster references the function __cpuinit
wakeup_secondary_cpu_via_mip() from a noninit section. So we've been
warned by the following warning. To avoid possible collision between
init/noninit, its best to mark the variable as __refdata.

 We were warned by the followin warning:

 LD      arch/x86/kernel/apic/built-in.o
WARNING: arch/x86/kernel/apic/built-in.o(.data+0x198c): Section
mismatch in reference from the variable apic_es7000_cluster to the
function .cpuinit.text:wakeup_secondary_cpu_via_mip()
The variable apic_es7000_cluster references
the function __cpuinit wakeup_secondary_cpu_via_mip()
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,
