Hi,
i found myself in presence of an odd start of the day memory layout
using Xen 3.0.1 testing on x86-64.
Quoting from <public/xen.h>:
" * 4. This the order of bootstrap elements in the initial virtual region:
* a. relocated kernel image
* b. initial ram disk [mod_start, mod_len]
* c. list of allocated page frames [mfn_list, nr_pages]
* d. bootstrap page tables [pt_base, CR3 (x86)]
* e. start_info_t structure [register ESI (x86)]
* f. bootstrap stack [register ESP (x86)]"
But when i run my domU kernel (homemade), i found myself with start_info
struct BETWEEN pt_base and end of page tables (pt_base + (nr_pt_frames
<< PAGE_SHIFT).
Is it intended?
Regards,
Mathieu

The comment is wrong. I'll fix it.
