Exactly right! There may be an easier way to get it too do that but I never figured it out and that linker script works just fine for me.

Frank,
Does that mean that your kernel is in two binaries? If so, I assume you load the 'initializer' portion into one page and the other part into another page?

Well no they are in the same binary and are linked together it's just that I page align my sections.

I see. So you padded the space between the sections until your second section is on a new page? Then you used paging to map the second section to higher half?
This sounds like a more straightforward way to do the higher half kernel.
