I was able to reproduce the syscallent part of this patch with
the following script:

$ git grep -l 'SEN(\(execv\|ipc\|socketcall\|ipc\)' |
  xargs -r sed -i -e '/SEN(execv/ s/TP|/&TSD|/' -e '/SEN(ipc)/ s/TI/&|TSD/' \
  -e '/SEN(socketcall)/ s/TD/&|TSD/' -e '/SEN(syscall)/ s/0,/TSD,/'

Could you add a reproducer script to the commit message, please?
