Define a global mapping structure to manage the mapping of userspace
Keys to hardware KeyIDs in MKTME (Multi-Key Total Memory Encryption).
Implement helper functions that access this mapping structure.
Why is a key “void *”?  Who owns the memory?  Can a real type be used?
It's of type "struct key" of the kernel key service.
Replacing void w 'struct key'.
