SVN rev 192027 on 2009-05-12 21:14:36Z by stas
- Eliminate extra register reads by using a variable to store
registers contents.
- Use memory barriers to preserve the order of buffer space operations.
This might be needed if we'll ever use this driver on architectures
where ordering is not guaranteed.
