RE: [Xen-devel] [PATCH][RESEND] Control panel changes for IA64/VTI

BTW, the reason for an ia64 specific get_pfn_list (by Matt) is that machine 
pages for domain on ia64 are allocated on demand. So there's requirement for 
parameters to contain start_pfn and nr_pages so that Xen can allocate necessary 
pages for that specific range. On x86 side, since all the pages are allocated 
when domain creation, get_pfn_list is aimed to query once for all pages and so 
the parameter can be only nr_pages. Just the background here. ;-)
