Thanks.

Here is a bonus fixup for a small issue noticed by Sergei yesterday.

From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Subject: [PATCH] ide: ide_timing_compute() fixup

XFER_SW_DMA_0 mode should be excluded from the extended cycle
timing computations.

[ This is just a documentation fix -- code inside the affected
'if' block already makes sure to accept only PIO modes. ]
