 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
+tested on ARM), 3.4, 3.5, 3.8, 3.9-rc on x86 64-bit. 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.
+LTTng 0.x clocks will be added back soon into LTTng 2.0.
