[Xen-devel] [PATCH] Make CONFIG_ATA_DMA and CONFIG_ATA_PIO32 default on

[Paul Durrant <paul.durrant@xxxxxxxxxx>]

Currently running make defconfig will leave the above turned off which,
at least for the Xen/QEMU use-case, means VMs will boot very slowly.
There seems to have been some concern over non-QEMU use of ATA_DMA about
five years ago, but I can find no particular concern over ATA_PIO32.
Given the increased use of QEMU and Xen in that period it would seem
like a good idea to default both of these on now. This patch does that.
