Please also note that: - assebet_defconfig currently doesn't even enable ide-cs (CONFIG_BLK_DEV_IDECS) in the mainline kernel - neponset_defconfig doesn't even enable IDE (CONFIG_IDE) in the mainline kernel so there is no risk of breaking anything.. * 'v4.9-rc2-arm-configs-pata' of https://github.com/bzolnier/linux: arm: spitz_defconfig: convert to use libata PATA drivers arm: s3c2410_defconfig: convert to use libata PATA drivers arm: netwinder_defconfig: convert to use libata PATA drivers arm: jornada720_defconfig: convert to use libata PATA drivers arm: ixp4xx_defconfig: convert to use libata PATA drivers arm: h3600_defconfig: convert to use libata PATA drivers arm: corgi_defconfig: convert to use libata PATA drivers arm: am200epdkit_defconfig: convert to use libata PATA drivers arm: omap1_defconfig: convert to use libata PATA drivers arm: collie_defconfig: convert to use libata PATA drivers arm: shannon_defconfig: disable IDE subsystem arm: mainstone_defconfig: disable IDE subsystem arm: lart_defconfig: disable IDE subsystem arm: cerfcube_defconfig: disable IDE subsystem arm: badge4_defconfig: disable IDE subsystem arm: assabet_defconfig: disable IDE subsystem
