Add support for 4MB pages. This includes the .text, .data, .data parts

of the kernel, and also most of the dynamic parts of the kernel.  Additionally,
4MB pages will be allocated for display buffers as appropriate (only.)

The 4MB support for SMP isn't complete, but doesn't interfere with operation
either.
