      Description

      In the Intel libvm.c we do:

      unsigned int vp_hn; /* the high nibble of the vp address value */
      vp_hn = localVirtualProcessorAddress >> 28;
      if (vp_hn < 3 || !inRVMAddressSpace(localVirtualProcessorAddress))

      that asserts that the high nibble of objects must be above 0x30000000 making it impossible to fully use the heap. The high nibble tests should be removed.
