Base Device Driver and DLL to allow execution of arbitrary user code in Ring 0. Includes SYSCALL.SYS.

The idea was to have an interfacing DLL to be used by an application. That DLL will return to the caller an entry point that will allow the caller to execute user functions in Ring 0.

It uses the syscall/sysret instructions as the fastest way to enter Ring 0.
