This is often because prepare_page_table lacks a __initdata annotation or the annotation of (unknown) is wrong. Mark the function as __init to avoid the warning regardless of the inlining, and remove the 'inline' keyword. The compiler is free to ignore the 'inline' here and it doesn't result in better object code or more readable source.
