-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). Kernels 2.6.32 to 2.6.34 need up to 3 patches applied
-(refer to linux-patches within the lttng-modules tree). 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.
