QEMU ATA hard disk not detected

Dear Linux folks, In QEMU 2.11 a disk is only detected by the AHCI driver and not by libata. On QEMU’s Standard PC (i440FX + PIIX, 1996), that causes an attached drive not to be detected as that machine doesn’t support AHCI. Here is the output with the machine Standard PC (Q35 + ICH9,

Hi Stephen, can you please add the for-linus branch of git://git.infradead.org/users/hch/dma-mapping.git to linux-next? You already carry the for-next branch, but it turns out I'll need another branch for late fixes so that for-next can remain unmerged and unrebased.
