[Greg KH]

2.6.28-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Adrian Bunk <bunk@xxxxxxxxxx>

commit e0212e72186e855027dd35b37e9d7a99a078448c upstream.

m68knommu does not set the Kconfig NO_DMA variable, but also does
not provide the required functions, resulting in the following
build error triggered by commit a40c24a13366e324bc0ff8c3bb107db89312c984
(net: Add SKB DMA mapping helper functions.):
