  • Create a dedicated region of kernel virtual memory for permanent mappings.
  • Map text video memory there instead of the current hack of allocating mapped pages and then remapping those pages.

This is done in preparation for local APIC support: the APIC's memory-mapped registers will be mapped in this region as well. This will likely also be useful to map ACPI tables.
