Joao Martins 2beea70a3e mm/sparse-vmemmap: refactor core of vmemmap_populate_basepages() to helper 
In preparation for describing a memmap with compound pages, move the
actual pte population logic into a separate function
vmemmap_populate_address() and have a new helper vmemmap_populate_range()
walk through all base pages it needs to populate.

While doing that, change the helper to use a pte_t* as return value,
rather than an hardcoded errno of 0 or -ENOMEM.
