...Need a little kernel programming help...

We are trying to add some functionality to the kernel for a research
project. One of the things we need to do is clone a process ourselves.
  We can't (or don't want to) call fork() or clone() directly, because
we need to maintain a pointer to the new task, and perform some
modifications before the task runs.

We've created a syscall, and are using the _syscall1 macro to make the
syscall from userspace. We think that our problem is related to the
struct pt_regs parameter to copy_process(). The sys_fork() and
sys_clone() syscalls get the regs as a parameter, but we don't.

How do we get the struct pt_regs that we need to pass to copy_process()
to achieve the correct behavior?
