This has been pending for a very long time now.
This patch brings libata up to similar standards as Linux IDE
with support for things like hdparm -I (identify) and -C (check power)
among others on ATAPI drives.
Andrew, can you pick this up for -mm ??

My reluctance stems mainly from the modifications to the hot path. ATA
and ATAPI need wholly different command simulations, so I don't like
your modification of sending both ATA and ATAPI devices to the same
simulation function -- only to have to disambiguate with an ATA-or-ATAPI
test.
I would rather keep the branch in the queuecommand hook the same. That
should keep the ATA device callpath unchanged, while enabling what you
want on the ATAPI callpath.
