The ID reg override handling code uses a rather elaborate data structure that relies on statically initialized absolute address values in pointer fields. This means that this code cannot run until relocation fixups have been applied, and this is unfortunate, because it means we cannot discover overrides for KASLR or LVA/LPA without creating the kernel mapping and performing the relocations first. This can be solved by switching to place-relative relocations, which can be applied by the linker at build time. This means some additional arithmetic is required when dereferencing these pointers, as we can no longer dereference the pointer members directly. So let's implement this for idreg-override.c in a preliminary way, i.e., convert all the references in code to use a special accessor that produces the correct absolute value at runtime.
