Can we please make these a global number space? I don't want to have any user space code "accidently" call this mmap while it's trying to find out if it can map the PIO page. We already have a global number space for CAPs.
I consider a vma with holes in it pretty ugly, and we've got the
mechanism for userspace to correctly find out where to find what.
I do prefer a contiguous vma and the existing capabilities/queries.
Avi?
