# execve _____________________________________________________
#
# In kernels < 3.7, sys_execve() was in arch-specific code (and had
# varying arguments). It was just a wrapper around generic
# do_execve(), but the wrapper could error out before calling
# do_execve(). So, we'll have to handle it in arch-specific tapset
# code to catch all calls.
