 So far, it has been tested on vanilla Linux kernels 2.6.38, 2.6.39, 3.0,
 3.1, 3.2, 3.3 (on x86 32/64-bit, and powerpc 32-bit at the moment, build
-tested on ARM). It should work fine with newer kernels and other
-architectures, but expect build issues with kernels older than 2.6.36.
-The clock source currently used is the standard gettimeofday (slower,
-less scalable and less precise than the LTTng 0.x clocks).  Support for
-LTTng 0.x clocks will be added back soon into LTTng 2.0.  Please note
-that lttng-modules 2.0 can build on a Linux kernel patched with the
-LTTng 0.x patchset, but the lttng-modules 2.0 replace the lttng-modules
-0.x, so both tracers cannot be installed at the same time for a given
-kernel version.
