[git patches] libata updates

Jeff Garzik
2006-12-14T23:27:58Z

Includes some pre-window-closing stuff (new drivers), but I was waiting
on some bug fixes before pushing.

Please pull from 'upstream-linus' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/libata-dev.git upstream-linus

to receive the following updates:
