For LTTng 2.6.29-lttng-0.124 I see the same errors as shown below:

In file included from include/linux/trace-clock.h:13,
                 from include/linux/ltt-tracer.h:22,
                 from kernel/marker.c:29:
linux-2.6-lttng/arch/powerpc/include/asm/trace-clock.h: In function
‘trace_clock_read32’:
linux-2.6-lttng/arch/powerpc/include/asm/trace-clock.h:18: error: implicit
declaration of function ‘get_tbl’
linux-2.6-lttng/arch/powerpc/include/asm/trace-clock.h: In function
‘trace_clock_read64’:
linux-2.6-lttng/arch/powerpc/include/asm/trace-clock.h:23: error: implicit
declaration of function ‘get_tb’
make[1]: *** [kernel/marker.o] Error 1
make: *** [kernel] Error 2
[root at srikant linux-2.6-lttng]#

Seems still the error exists.
