22	/** @page pg_cpum CPUM - CPU Monitor / Manager
23	*
24	* The CPU Monitor / Manager keeps track of all the CPU registers. It is
25	* also responsible for lazy FPU handling and some of the context loading
26	* in raw mode.
27	*
28	* There are three CPU contexts, the most important one is the guest one (GC).
29	* When running in raw-mode (RC) there is a special hyper context for the VMM
30	* part that floats around inside the guest address space. When running in
31	* raw-mode, CPUM also maintains a host context for saving and restoring
32	* registers accross world switches. This latter is done in cooperation with the
33	* world switcher (@see pg_vmm).
34	*
35	* @see grp_cpum
