Ok, I didn't know that, thanks for pointing it out.

Now ident_mapping_init is checking if pgd/pud is present for every 2M,
so several 2Ms are in same PUD, it will keep checking if pud is there.
init_level4_page does not check existing pgd/pud.
We could use generic mapping_init to replace them all.
