If you think there's not going to be big ongoing conflicts in this 
specific code in the next month leading up to the .31 merge window, 
and if you ack all the changes, i'd be glad to merge this patch into 
the tracing tree.

I do daily builds of powerpc defconfig, which has these spufs 
settings:

 #
 # Cell Broadband Engine options
 #
 CONFIG_SPU_FS=m
 CONFIG_SPU_FS_64K_LS=y
 # CONFIG_SPU_TRACE is not set

so spufs is build-tested, but spu-trace is not - but with 
Christoph's patch the tracing facility would be available 
unconditionally, so that would get (build) tested as well,
and propagated to linux-next.
