[PATCH 0/2] Hyper-V disk support V4

From: Andy Whitcroft
Date: Thu Apr 19 2012 - 10:33:25 EST

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
