Replacing FBSD mutexes

[elekktretterr at exemail.com.au]

I'm working on a new port of the nvidia driver to learn more about OS
programming.

What is the proper way to replace FreeBSD mutex locks?

Such as:

mtx_init(&mtx->mutex_mtx, "os.mutex_mtx", NULL, MTX_DEF | MTX_RECURSE);

mtx_lock(&mtx->mutex_mtx);
