Message:

A lot of untested sparc64 stuff:

• Write ASID to hardware when a thread is about to run in userspace.
• Add userspace() and switch_to_userspace() functions.
• Handle special cases when the userspace spill/fill handler causes MMU trap.
• Resolve some TODOs in the existing sparc64 code.
• sparc64 has now C99 compliant header guards.
• Formatting and indentation fixes.
