Subject[git patches] libata fixes

The only notable: GregKH wanted the pci_reenable_device() change
associated with ata_piix to go in before the release, to avoiding
release with an imperfect API.

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:
