    Subject[PATCH 0/2] Hyper-V disk support V4
    Add support for ignoring disks devices on specific host controllers to
    libata. Use this support to trigger us to ignore Hyper-V disk devices
    on the emulated SATA device based on the system DMI information.

    I have cleaned up the Hyper-V detection so it is only included when the
    paravirtualised drivers are enabled. I have also reintroduced the
    override which had mysteriously gone missing in V3.



    - only enable the quirk when the paravirtualised drivers are compiled
    - fix up the command line flag to disable this support

    - switch detection method to DMI information

    - create a generic libata quirk
    - switch detection to piix_init_one

    Andy Whitcroft (2):
    libata: add a host flag to ignore detected ATA devices
    ata_piix: defer disks to the Hyper-V drivers by default
