Added a very basic types.h header file that defines NULL, size_t and

time_t.
Moved the kernel's loading point down to address 0 in
conventional memory and updated linker scripts accordingly.
Began to experiment with loading a binary blob into extended memory
(0x100000), switching to userspace mode, and executing it.
