Thanks, it builds.  And runs mostly.  With full preemption #4 in 
the make oldconfig in effect, elevator=cfq on the vmlinuz command line, 
and tvtime-9.15 in particular seems
to be haveing a problem.  No video is delivered to the blue screened 
window.  Sound is working ok though.

And the log has several thousand of these:

I presume the default traceing options are using too much
time in logging, hence the dma failure, but thats a not
very scientific guess on my part.

I also reported this in a previous test of one of the 47-xx
kernels I'd managed to make build with the git2 patch also
applied.  That was with some pretty large offsets, 300+ lines
in one case.  That message wasn't ack'd, probably lost in the noise.

Is there some specific xconfig traceing option I can turn off
that will restore tvtime, or is the above a genuine breakage?

Or will tvtime require a rewrite for compatibility with this
new code framework?
