Does it allow to disable virtual memory? #450

The generated kernel prints virtual_addr, does it allow to disable virtual memory? Because implicitly adding these features makes a kernel not so lightweight.

Is it the QEMU Seabios output? Perhaps, I mistook the output as from this bootloader.

Blog os is written for 64bit x86 (x86_64), which does not allow disabling paging. Only 16bit and 32bit x86 allow disabling it. If you try entering long mode with paging disabled you will get a #GP fault (general protection fault).
