1Dexuan Cui <dexuan.cui@intel.com>: I got the following patch from lttng dev
2mailing list:
3http://lists.casi.polymtl.ca/pipermail/ltt-dev/2011-February/003903.html
4The patch looks good and I think it would be in next release. At present,
5let's add it into SRC_URI.
6
7-----------------------------------------------------------------
8The PPC version of the trace_clock_read64 was using the TB register
9which is not constant accross implementations. The currently
10measured time base on PPC was not accurate.
11So, for now, we rely on the CLOCK_MONOTONIC.
12
13This patch remove a bunch of #ifdef for x86 and PPC, since we now rely on
14the same base clock. It also fix the build on PPC that was currently broken
