We add this basic functionality to the Kernel so Userspace can request a particular virtual memory mapping to be immutable. This will be useful later on in the DynamicLoader code. The annotation of a particular Kernel Region as immutable implies that the following restrictions apply, so these features are prohibited: - Changing the region's protection bits - Unmapping the region - Annotating the region with other virtual memory flags - Applying further memory advises on the region - Changing the region name - Re-mapping the region
