Tejun Heo 40a1d531f6 libata: kill ATA_HORKAGE_DMA_RW_ONLY
ATA_HORKAGE_DMA_RW_ONLY for TORiSAN is verified to be subset of using
DMA for ATAPI commands which aren't aligned to 16 bytes.  As libata
now doesn't use DMA for unaligned ATAPI commands, the horkage is
redundant.  Kill it.

Tejun Heo 55f3952d45 libata: kill the infamous abnormal status message
The infamous abnormal status message triggers on not so abnormal cases
including empty port and even when it's being triggered on actual
errors the info it provides is redundant and out of context - higher
level functions will print the info in better safe later anyway.

Also, by being triggered all the time, it leads people to think that
the abnormality is somehow related to all ATA and system problems
they're experiencing and gives owners of healthy systems unfounded
doubts about the integrity of the universe.  Make it a DPRINTK and
save the universe.

If I insert an artificial bug right before loading init, I get this:
