Prepare for memory hotplugging support by changing from __init to __meminit for the page table functions that are used by the upcoming architecture specific callbacks. Changing the __init attribute to __meminit, avoids that the functions are removed after init. The __meminit attribute makes sure the functions are kept in the kernel text post init, but only if memory hotplugging is enabled for the build.
