Creating a system call to get data from userspace is reinventing the wheel in an octangular way because it makes the userland part rather difficult while the kernel interface is almost the same (it uses copy_from_user()). Just create a character device, let userland open(), read(), and write() it. It's all documented in Linux Device Drivers, 3rd edition (available for free at lwn.net).
