Log:
  Remove support for running 32-bit kernels on 64-bit hardware.
  
  This was useful in bring up. However, it causes more issues than the
  support is worth (64-bit atomics being chief among them).

+	The XLP config has been removed. We can't support 64-bit atomics in this
+	kernel because it is running in 32-bit mode. XLP users must transition
+	to running a 64-bit kernel (XLP64 or XLPN32).
