I should have spotted this myself infact. I split these patches out of a
huge series and did infact check that it builds outside the series.
looks like i missed a define. Would it be possible, that patch 4 of my
series flows via Ralfs MIPS tree ? That way we dont need to split out a
single "#define ltq_ebu_w32_mask" out of the bigger MIPS series ?

Sorry about this,
