iommu: dmar: fix harmless section mismatch warning
PATCH 1/1 iommu: dmar: fix harmless section mismatch warning
Building with gcc-4.6 results in this warning due to dmar_table_print_dmar_entry being inlined as in newer compiler versions:
WARNING: vmlinux.o(.text+0x5c8bee): Section mismatch in reference from the function dmar_walk_remapping_entries() to the function .init.text:dmar_table_print_dmar_entry() The function dmar_walk_remapping_entries() references
the function __init dmar_table_print_dmar_entry().
This is often because dmar_walk_remapping_entries lacks a __init
annotation or the annotation of dmar_table_print_dmar_entry is wrong.
This removes the __init annotation to avoid the warning. On compilers that don't show the warning today, this should have no impact since the function gets inlined anyway.

Applied, thanks.
