Hi Naresh,
Sorry for that, the __NR_execve definition for i386 was deleted
by mistake in the commit ece7f7c0507c ("perf bench syscall: Add
fork syscall benchmark").
Could you please help to check whether the build error can be
fixed with the following changes? If yes, I will send a formal
patch as soon as possible, thank you.
