Subject: [RFC 0/2] arm64: Enable vmemmap from device memory

This series enables vmemmap mapping allocation from device memory ranges on
arm64. Before that it enables vmemmap_populate_basepages() to accommodate
struct vmem_altmap based requests.

This series is based on linux next (next-20190613) along with v6 arm64
hot-remove series [1].
