Abstract: This project enables NetBSD to have physical ram pages dynamically added via uvm_page_physload() and dynamically removed using a complimentary function.

Rationale: Makes NetBSD a viable datacentre OS, with hotspare RAM add/remove support.

Deliverables:

Implementation:

Further api and infrastructural changes may be required to accommodate these changes. The physical page management code will need to be enhanced to more than a fixed array, while taking into account memory attribute related tagging information.
