Not sure what is the reason to setup entry point to virtual address.

stext etc better stay as the virtual address through this change.  The
kernel makes use of all stext/etext etc symbols as virtual addresses.

I am not changing stext to physical address. Just elf entry point.
What's it reason to have entry point in virtual address space?

Thanks,
Michal
