Merge tag 'ata-7.0-final' of git://git.kernel.org/pub/scm/linux/kernel/git/libata/linux
Pull ata fix from Niklas Cassel:
- Add a quirk for JMicron JMB582/JMB585 AHCI controllers such that
they only use 32-bit DMA addresses.
While these controllers do report that they support 64-bit DMA
addresses, a user reports that using 64-bit DMA addresses cause
silent corruption even on modern x86 systems (Arthur)
