Hi Jerome,

Which line in the license are you concerned about ? In theory we're using the same license as the initial code pushes for radeon, and I just did a side-by side compare with the license header on cik.c in the radeon tree and confirmed that the two licenses are identical. 

The cik.c header has an additional "Authors:" line which the kfd files do not, but AFAIK that is not part of the license text proper.
