Subject[git patches] libata fixes

There were some bumps, but I'm surprised at the lack of ACPI problem
reports. It did live in -mm for many months, but nonetheless... we'll
see how 2.6.21 release goes.

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:
