Sorry, I thought this gerrit is available for everyone in R/O mode.

And another sorry for thinking this is smatch. Actually the "offender"
is gcc 4.8. It improved the output and now prints the entire line where
the problem is. E.g.:

arch/x86/kernel/e820.c: In function ‘e820_setup_gap’:
arch/x86/kernel/e820.c:630:6: warning: variable ‘found’ set but not used [-Wunused-but-set-variable]
  int found;
      ^

               ^

     ^

I need to adapt Aiaiai's log parser to handle these.

I'll send you a note when I meed the problematic smatch output which
contained a lot of line numbers for mutexes.

Thanks!
