    mm: Fix section mismatch of zero_free_pages
    
    zero_free_pages is used not only from boot code:
    
    WARNING: vmlinux.o(.text+0x21f668): Section mismatch in reference from the function __free_pages_ok() to the variable .init.data:zero_free_pages
    The function __free_pages_ok() references
    the variable __initdata zero_free_pages.
    This is often because __free_pages_ok lacks a __initdata
    annotation or the annotation of zero_free_pages is wrong.
