Comment(by bdubbs@…):

 We got a fix on gcc bugzilla.  I still don't know if the bug was in the
 kernel or gcc, but the following change to the kernel works around the

 sed -i -e "s/inline void rdtsc_barrier/__always_inline void rdtsc_barrier/

 The fix was just submitted today.  We'll have to check future releases to
 see when it makes it into the released version.
