I did not have time recently to work on RELOCATABLE kernel, but that now 
changed and I'm going to pursue this work.

But you can see that my last patchset was not well received, so a fresh 
look could be great.

So maybe you could:

- review my last patchset v5 (and take a look at what I tried before in 
the previous versions) and check how other archs implement relocatability
- review Zong's KASLR implementation and see how KASLR could fit on top 
of my v5

And all along this process, we can discuss to find the best approach.

On my side, I will now rebase my work on top of master to refresh my 
memories and I will share a branch here when it works.

Thanks for proposing to help, relocatable kernel prevents sv48 and KASLR 
implementation to be integrated so that would be great to "fix" this.
