The reasons ia64 kernel does are

1. EPC segment has to be marked PF_X without PF_R.
2. We can only have one PT_LOAD segment in vDSO.

ia64 kernel uses

PHDRS
{
  readable PT_LOAD FILEHDR PHDRS FLAGS(4); /* PF_R */
  epc PT_LOAD FILEHDR PHDRS FLAGS FLAGS(1); /* PF_X */
  dynamic PT_DYNAMIC FLAGS(4); /* PF_R */
  unwind 0x70000001; /* PT_IA_64_UNWIND, but ld doesn't match the name */
}

so that ld.so can treat readable and epc segments as a single
segment with data and text. ld.so can map a single segment with
data and text parts.
