46  *    | cmdline_paddr  | Physical address of the command line,

51  *    | memmap_paddr   | Physical address of the (optional) memory map. Only
52  *    |                | present in version 1 and newer of the structure.
54  *    | memmap_entries | Number of entries in the memory map table. Only
55  *    |                | present in version 1 and newer of the structure.
61  * The layout of each entry in the module structure is the following:
64  *    | paddr          | Physical address of the module.
66  *    | size           | Size of the module in bytes.
68  *    | cmdline_paddr  | Physical address of the command line,
74  * The layout of each entry in the memory map table is as follows:
79  *    | size           | Size of mapping in bytes
81  *    | type           | Type of mapping as defined between the hypervisor
92  * Version numbers of the hvm_start_info structure have evolved like this:
96  * Version 1:   Added the memmap_paddr/memmap_entries fields (plus 4 bytes of
97  *              padding) to the end of the hvm_start_info struct. These new
100  *              of the structure must check that memmap_entries is non-zero
106  * C representation of the x86/HVM start info layout.
108  * The canonical definition of this layout is above, this is just a way to
