Impact: fix crash with memory hotplug enabled kernel_physical_mapping_init() is called during memory hotplug so it does not belong in the init section. If the kernel is built with CONFIG_DEBUG_SECTION_MISMATCH=y on the make command line, arch/x86/mm/init_64.c is compiled with the -fno-inline-functions-called-once gcc option defeating inlining of kernel_physical_mapping_init() within init_memory_mapping(). When kernel_physical_mapping_init() is not inlined it is placed in the .init.text section according to the __init in it's current declaration. A later call to kernel_physical_mapping_init() during a memory hotplug operation encounters an int3 trap because the .init.text section memory has been freed. This patch eliminates the crash caused by the int3 trap by moving the non-inlined kernel_physical_mapping_init() from .init.text to .meminit.text.
