[PATCH] x86: fix section mismatch warnings in kernel/setup_percpu.c

[PATCH] x86: fix section mismatch warnings in kernel/setup_percpu.c

[Leonardo Potenza]

From: Leonardo Potenza <lpotenza@inwind.it>

The function setup_cpu_local_masks() has been marked __init, in order to remove the following section mismatch messages:

WARNING: vmlinux.o(.text+0x3c2c7): Section mismatch in reference from the function setup_cpu_local_masks() to the function .init.text:alloc_bootmem_cpumask_var()
The function setup_cpu_local_masks() references
the function __init alloc_bootmem_cpumask_var().
This is often because setup_cpu_local_masks lacks a __init 
annotation or the annotation of alloc_bootmem_cpumask_var is wrong.

WARNING: vmlinux.o(.text+0x3c2d3): Section mismatch in reference from the function setup_cpu_local_masks() to the function .init.text:alloc_bootmem_cpumask_var()
The function setup_cpu_local_masks() references
the function __init alloc_bootmem_cpumask_var().
This is often because setup_cpu_local_masks lacks a __init 
annotation or the annotation of alloc_bootmem_cpumask_var is wrong.

WARNING: vmlinux.o(.text+0x3c2df): Section mismatch in reference from the function setup_cpu_local_masks() to the function .init.text:alloc_bootmem_cpumask_var()
The function setup_cpu_local_masks() references
the function __init alloc_bootmem_cpumask_var().
This is often because setup_cpu_local_masks lacks a __init 
annotation or the annotation of alloc_bootmem_cpumask_var is wrong.

WARNING: vmlinux.o(.text+0x3c2eb): Section mismatch in reference from the function setup_cpu_local_masks() to the function .init.text:alloc_bootmem_cpumask_var()
The function setup_cpu_local_masks() references
the function __init alloc_bootmem_cpumask_var().
This is often because setup_cpu_local_masks lacks a __init 
annotation or the annotation of alloc_bootmem_cpumask_var is wrong.
