Subject: [PATCH] x86: Fix section mismatches in mpparse.

Impact: fix section mismatch

In arch/x86/kernel/mpparse.c, smp_reserve_bootmem() has been called
and also refers to a function which is in .init section. Thus causes
the first warning. And check_irq_src() also requires an __init,
because it refers to an .init section.

Thanks

WARNING: arch/x86/kernel/built-in.o(.text+0x10881): Section mismatch
in reference from the function smp_reserve_bootmem() to the function
.init.text:get_mpc_size()
The function smp_reserve_bootmem() references
the function __init get_mpc_size().
This is often because smp_reserve_bootmem lacks a __init
annotation or the annotation of get_mpc_size is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x108d9): Section mismatch
in reference from the function check_irq_src() to the function
.init.text:get_MP_intsrc_index()
The function check_irq_src() references
the function __init get_MP_intsrc_index().
This is often because check_irq_src lacks a __init
annotation or the annotation of get_MP_intsrc_index is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x108ed): Section mismatch
in reference from the function check_irq_src() to the function
.init.text:assign_to_mpc_intsrc()
The function check_irq_src() references
the function __init assign_to_mpc_intsrc().
This is often because check_irq_src lacks a __init
annotation or the annotation of assign_to_mpc_intsrc is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x10908): Section mismatch
in reference from the function check_irq_src() to the function
.init.text:print_mp_irq_info()
The function check_irq_src() references
the function __init print_mp_irq_info().
This is often because check_irq_src lacks a __init
annotation or the annotation of print_mp_irq_info is wrong.

WARNING: arch/x86/kernel/built-in.o(.text+0x1091a): Section mismatch
in reference from the function check_irq_src() to the variable
.init.data:m_spare
The function check_irq_src() references
the variable __initdata m_spare.
This is often because check_irq_src lacks a __initdata
annotation or the annotation of m_spare is wrong.
