[lttng-dev] compiling lttng 2.0.1 statically into kernel tree 3.4.0-rc7 fails

[Paul Barrette]

Hi all,
I added the lttng-module to my kernel tree with the goal of making it a
tristate option.  I added a Kconfig and a few Makefile changes (removed the
rules at end).  I am able to compile lttng-module as a module (M), but
compiling statically fails at link time with some redefinition errors (log
below).

Details:
target:  powerpc
kernel config:  mpc85xx_defconfig
lttng-modules 2.0.1 plus patch

commit 6bd5e64e29cf1c251632501e45d61be6f16257ba

    Fix: update signal instrumentation for 3.4 kernel

    Fix #226

 Any ideas?
