In theory they should be the same. What do you think is different?
in practice the x86-64 version returns "success" if there is one byte in the entire
memory range that complies with the requested type, even if the rest of the range is
of another type. What the ideal is for the purpose here is "is the entire range reserved",
but for now I'll settle for "is the start address reserved".
(and yes you can express the "is the start address reserved" as a question to the current function for
a 1 byte range, I probably should do that I suppose)
or why not check
if (type == ei->type && start >= ei->addr && end <= (ei->addr + ei->size))
return 1;
will this make the range check check stricter?
that's not going to cut it; you can have 2 e820 entries that together span the range
