Before you add memory_map.nr_map, you should be able to iterate
from 0 to (not inclusive) nr. At least as far as I recall the original
patch.
Sorry, I really don't understand what you want.
Before we add memory_map.nr_map, e820[0, nr) don't include low/high
memory, right?
Why? memory_map is representing the reserved areas only, isn't it?
If that's not the case, then of course everything is fine.
I'm pretty sure the memory map we get here is an extension of the
original PV-only get_e820 hypercall, which *does* include both the
lowmem and highmem regions.
In any case, it's pretty clear from the patched code that Tiejun is
removing the old code which created the lowmem and highmem regions and
is not replacing it. Where do you think the highmem region he's
looking for was coming from?
On second thoughts, I prefer to check/sync memory_map.map[] before copy
them into e820 since ultimately this can make sure hvm_info,
memory_map.map[] and e820 are on the same page.
Anyway, I would send out v10 to address others so please further post
your comments over there.
Thanks
Tiejun
