24	*

27	* @section sec_pg_modes Paging Modes
28	*
29	* There are three memory contexts: Host Context (HC), Guest Context (GC)
30	* and intermediate context. When talking about paging HC can also be refered to
31	* as "host paging", and GC refered to as "shadow paging".
32	*
33	* We define three basic paging modes: 32-bit, PAE and AMD64. The host paging mode
34	* is defined by the host operating system. The mode used in the shadow paging mode
35	* depends on the host paging mode and what the mode the guest is currently in. The
36	* following relation between the two is defined:
37	*
38	* @verbatim
39	Host > 32-bit \| PAE \| AMD64 \|
40	Guest \| \| \| \|
41	==v================================
42	32-bit 32-bit PAE PAE
43	-------\|--------\|--------\|--------\|
44	PAE PAE PAE PAE
45	-------\|--------\|--------\|--------\|
46	AMD64 AMD64 AMD64 AMD64
47	-------\|--------\|--------\|--------\| @endverbatim
48	*
49	* All configuration except those in the diagonal (upper left) are expected to
50	* require special effort from the switcher (i.e. a bit slower).
51	*
52	*
53	*
54	*
55	* @section sec_pg_shw The Shadow Memory Context
56	*
57	*
58	* [..]
59	*
60	* Because of guest context mappings requires PDPTR and PML4 entries to allow
61	* writing on AMD64, the two upper levels will have fixed flags whatever the
62	* guest is thinking of using there. So, when shadowing the PD level we will
63	* calculate the effective flags of PD and all the higher levels. In legacy
64	* PAE mode this only applies to the PWT and PCD bits (the rest are
65	* ignored/reserved/MBZ). We will ignore those bits for the present.
66	*
67	*
68	*
69	* @section sec_pg_int The Intermediate Memory Context
70	*
71	* The world switch goes thru an intermediate memory context which purpose it is
72	* to provide different mappings of the switcher code. All guest mappings are also
73	* present in this context.
74	*
75	* The switcher code is mapped at the same location as on the host, at an
76	* identity mapped location (physical equals virtual address), and at the
77	* hypervisor location.
78	*
79	* PGM maintain page tables for 32-bit, PAE and AMD64 paging modes. This
80	* simplifies switching guest CPU mode and consistency at the cost of more
81	* code to do the work. All memory use for those page tables is located below
82	* 4GB (this includes page tables for guest context mappings).
83	*
84	*
85	* @subsection subsec_pg_int_gc Guest Context Mappings
86	*
87	* During assignment and relocation of a guest context mapping the intermediate
88	* memory context is used to verify the new location.
89	*
90	* Guest context mappings are currently restricted to below 4GB, for reasons
91	* of simplicity. This may change when we implement AMD64 support.
92	*
93	*
94	*
95	*
96	* @section sec_pg_misc Misc
97	*
98	* @subsection subsec_pg_misc_diff Differences Between Legacy PAE and Long Mode PAE
99	*
100	* The differences between legacy PAE and long mode PAE are:
101	* -# PDPE bits 1, 2, 5 and 6 are defined differently. In leagcy mode they are
102	* all marked down as must-be-zero, while in long mode 1, 2 and 5 have the
103	* usual meanings while 6 is ignored (AMD). This means that upon switching to
104	* legacy PAE mode we'll have to clear these bits and when going to long mode
105	* they must be set. This applies to both intermediate and shadow contexts,
106	* however we don't need to do it for the intermediate one since we're
107	* executing with CR0.WP at that time.
108	* -# CR3 allows a 32-byte aligned address in legacy mode, while in long mode
109	* a page aligned one is required.
