ahci: implement AHCI_HFLAG_NO_FPDMA_AA and update NV quirks
It turns out different generations of MCPs have differing quirks. * MCP 65-73 : FPDMA AA broken, lies about PMP support, forgets to report NCQ * MCP 77-79 : FPDMA AA broken, lies about PMP support * MCP 89 : FPDMA AA broken Instead of turngin off FPDMA AA on all NVIDIAs, implement HFLAG_NO_FPDMA_AA, define additional board IDs and apply necessary quirks. This fixes bko#15481 and the list of quirks is verified by Peer Chen. http://bugzilla.kernel.org/show_bug.cgi?id=15481 Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Peer Chen <pchen@nvidia.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
