Both.  The ucc_geth driver calls qe_muram_alloc() with spinlocks held.  The 8610
DIU driver does something similar, but it's targeted for 2.6.26.

I'm hesitant to recommend inclusion in 2.6.25 because I haven't tested the fix
throughly enough to know that it doesn't break something else.  Technically, it
could result in qe_muram_alloc() failing.
