RAID operations cause a system hang on platforms with DCA
(Direct-Cache-Access) enabled. So turn off RAID capabilities in this
case.

ioat: silence "dca disabled" messages2009-11-17T18:34:31ZDan Williams2009-11-17T18:34:31Zurn:sha1:e22dde9904c2d26a522f1a2b89854a8238bf0933
Turning off dca is not an "error", and the dca-enabled state can be
viewed from sysfs.

ioat: move to drivers/dma/ioat/2009-07-28T21:32:12ZDan Williams2009-07-28T21:32:12Zurn:sha1:584ec22759c06cdfc189c03a727f20038526245b
When first created the ioat driver was the only inhabitant of
drivers/dma/. Now, it is the only multi-file (more than a .c and a .h)
driver in the directory. Moving it to an ioat/ subdirectory allows the
naming convention to be cleaned up, and allows for future splitting of
the source files by hardware version (v1, v2, and v3).
