[lttng-dev] [PATCH lttng-modules] Fix possible kernel build errors with linux-patches

[Andrew Gabbasov]

Kernel sources of version 2.6.32 - 2.6.34 with applied patches
from linux-patches may fail to compile if tracepoint samples
are configured to build. Some part of backported commits
are added to the kernel patches to avoid those errors.
