  Log:
  Use a TR of size 1 << IA64_ID_PAGE_SHIFT instead of 16M to avoid
  overlapping TR/TC entries (which results in a machine check). Note
  that we don't look at the size of the memory descriptor, because
  it doesn't guarantee non-overlap.
  
  With this change, a UP kernel could boot on a Intel Tiger4 machine
  with the following options:
  
  options         LOG2_ID_PAGE_SIZE=26            # 64M
  options         LOG2_PAGE_SIZE=14               # 16K
