I didn't really get your question.

Linux kernel starts at a fixed location in virtual space. This is
called PAGE_OFFSET. On a kernel split of 3GB/1GB, 32 system, its is
0xC000_0000. You can have a look at file after compiling
your kernel.
When cpu runs with MMU on, your cpu generates virtual address.
