In the patch below, usage of __kernel_ulong_t and __kernel_long_t is
introduced, but that is not available on older system (fedora-14, at least).
It is not a #define, so I am having trouble finding a quick hack
around this.
Any ideas on how to make this work better on older OSs running
modern kernels?

Child: c7ec7697e3f000359aa317394e6dd972e35c1f84 (Fix build on fedora-14 (and
other older systems))
Branches: master, remotes/origin/master
Follows: v3.10.0
Precedes:
add more uapi header files
In order to ensure no backward/forward compatiablity problems,
make sure that all kernel headers used come from the local copy.
