+ * we try to honour the memsz value for an ELF file like this
+ * we will end up with overlapping segments (which the
+ * loader.c code will later reject).
+ * We support ELF files using this scheme by by checking whether
+ * paddr + memsz for this segment would overlap with any other
+ * segment. If so, then we assume it's using this scheme and
+ * truncate the loaded segment to the filesz size.
