We can use pfn_to_page in realmode for other configs. Hence remove the

For CONFIG_SPARSEMEM and CONFIG_DISCONTIGMEM and others (I am struggling to
find the full list :) )? Are you sure about that? If I recall correctly, at
the time realmode_pfn_to_page() could not work for all of them, what changed?
That is one thing I wanted to check. Everything other than
SPARSEMEM_VMEMMAP should use linear mapping which can work with real
mode also right ? Or am i missing something ?

There is also a comment at the #endif with "FLATMEM", needs to be updated.
