+ *
+ * This file contains functions for virtual memory management.
+ * 
+ * Virtual Memory Management is still a work in progress.
+ * The functions here are hold-offs from old versions of the software implemented here, as well as from the EFI version of Chroma, called Sync.
+ * 
+ * There, these functions worked, but here, under BIOS, it's a lot more difficult.
+ * It will take some time to get these functions working.
+ * 
+ * The general plan, being that the BOOTBOOT loader has given us static addresses for all of our doodads,
+ *  is to keep the core kernel where it is (FFFFFFFFFFE00000) and load in modules and libraries around it.
+ * 
+ * We start in the higher half, so we'll dedicate the lower half (7FFFFFFFFFFF and below) to userspace.
+ * 
+ * That means we have about 3 terabytes of RAM for the kernel.
+ *  This will be identity mapped, always.
+ * 
+ * Handily, since most modern processors ignore the highest 2 bytes of a virtual address, and the kernel
+ *  is mapped to 0x80000000000 and above, we can use the nomenclature:
+ *      * 0x00007FFFFFFFFFFF and below is user space.
+ *      * 0xFFFF800000000000 and above is kernel space.
+ *  The processor will ignore the first 4 chars, and this provides a great deal of readability for the
+ *   future of the kernel.
+ * 
+ * We'll have a kernel heap mapped into this kernel space, as well as a kernel stack (for task switching and error tracing).
+ *  These will be 1GB each.
+ *      We may have to increase this in the future, once Helix is fully integrated.
+ *      Helix will take a lot of memory, as it is a fully featured 3D engine. We may have to implement things like
+ *       texture streaming and mipmapping. Minimising RAM usage is NOT a priority for me, but it would be nice
+ *        to have a minimum requirement above 32GB.
+ * 
+ *      // TODO: Expand Kernel Heap
+ * 
+ * 
+ * //TODO: there are lots of calls to AllocateFrame here, those need to be separated out into AllocateZeroFrame if necessary.
