+      <p>The purpose of this is to enable use of the Signal Processing
+	Engine found in the NXP/Freescale e500v2 SoC.  The SPE uses
+	opcodes overlapping with Altivec, so is mutually exclusive.
+	Additionally, the e500v2 does not have a traditional FPU, and
+	instead uses the SPE for all floating point operations (or
+	emulation as is currently done).  Combined with the fact that
+	the SPE ABI is incompatible with traditional ABI, a new
+	MACHINE_ARCH is created to address this.</p>
+
+      <p>A project branch has been created with the work.  A
+	powerpcspe kernel boots on the RouterBoard RB800, and base
+	utilities run properly.</p>

+	<p>Potentially optimizing setjmp/longjmp to not use SPE unless
+	  it's already been enabled.  This would save the kernel
+	  switch for processes that don't otherwise use the SPE.  This
+	  is a low priority task which may not be completed.</p>
