[Xen-users] Page Table questions

["Michael Levenhagen" <mjleven@xxxxxxxxxx>]

In section 3.3 of the XEN Interface manual it talks about a mode of 
operation where the guest can directly write it's page tables and then 
Xen traps the write attempt. How do I enable this mode?
I've noticed that PT_MODE_WRITABLE is included in the "__xen_guest" 
section of many examples I found in the mailing list archives. I can't 
find this string being used anywhere in the code. Is PT_MODE_WRITABLE 
deprecated?
arch/xen/i386/kernel/head.S has the following in "__xen_guest"

#ifdef CONFIG_XEN_SHADOW_MODE
       .ascii  ",SHADOW=translate"
#endif

yet I don't see it being referenced in xen/tools/libxc/xc_load_elf.c

Is there any documentation on valid "__xen_guest" entries and what they do?

thanks
Mike
