Unmapping the idmap range using 52bit PA is quite broken, as we don't take into account the right number of PGD entries, and rely on PTRS_PER_PGD. The result is that pgd_index() truncates the address, and we end-up in the weed.Let's introduce a new unmap_hyp_idmap_range() that knows about this, together with a kvm_pgd_index() helper, which hides a bit of the complexity of the issue.
