Subject[git patches] libata updates for 2.6.33

Nothing world-shakingly-notable. Notable notables:

- TRIM work from Christoph and mkp, to make SSD life a bit better
- PATA fixes and updates from Bart and Alan
- long overdue removal of 'experimental' tag from PATA driver submenu
in Kconfig
- various bug fixes and minor updates

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:
