This is not the prototype of sys_execve(). It looks like this :
asmlinkage int sys_execve(struct pt_regs regs)
this syscall is a little more tricky to track than the others, because the
pt_regs is not a pointer here. That means you can't just stick in a call
inbetween like with most syscalls.
Instead you should just copy the code from sys_execve() and call do_execve
directly from the module (it is exported, so you can).
but - you will need to do this for all architectures as they differ
and are you really sure you need to do this ?
