+    sys/sdt.h: set x86-64 STAP_SDT_ASM_CONSTRAINT back to "nor"
+    
+    It turns out the kernel and some other sdt consumers haven't learned
+    how to use %xmm registers in sdt operands.  So under this duress, stap
+    will go back to the old school integer register set "nor" as a
+    default.  We'll revisit this in the future, though this egg might not
+    turn into a chicken.
