Thanks for the reviews!

I'm not sure which branch should I use for rebasing (it doesn't seem that your
riscv-to-apply.next or riscv-to-apply.for-upstream branches are updated), so I 
rebased
it on top of 'master', fixed a couple of conflicts.

Let me know if you want a rebase based on a different branch. Thanks,

Daniel
