Sven-Haegar, Christoph,

concerning the issue below, I could reproduce both Sven-Haegar's error (running
make headers_check with the patch applied) and Christoph's build error with gcc
4.7 on i686 without the patch.

I noticed that neither syscall_trace_enter() nor syscall_trace_leave() were
called from C code, all were from pure asm. So I simply reverted the first
patch then removed the two function prototypes and everything is OK for me
now using gcc 4.7, i686 and x86_64.

I'm attaching the two patches here to be appled on top of 2.6.32.61, I would
like it if you could try in your environment to confirm that they correctly
fix the issue.

Thanks,
Willy
