Actually, I really hope kernel image is in the XKVRANGE, rather
than being in XKPRANGE. So that we can limit kernel and modules
be in 4GB range. I think it will make all work normally. :-(
Assuming that the kernel and modules are limited to 4G, the external
symbols will be accessed through pcrel32, which means that there is no
need to pass the GOT table entry and there is no need for got support
We'll still need to modify GCC to use PC-rel for accessing an object in
another TU (by default, or an option to control), instead of GOT. Or
just add support to GOT relocations here. But anyway it will be much
easier as we won't need to handle per-CPU variables specially.
