Description

Upstreaming SmartOS OS-6549:

Applications such as the coming bhyve will want userspace access to the regions of kmem allocated to be the guest memory. While seg_umap exists to achieve a similar purpose, it was designed to be very constrained (a single page) in its capabilities. Rather than updating that for now, a new segment driver with lessened restrictions could be created.
