Summary:                    Fails to Compile on Fedora FC9 with Kernel 2.6.27 -
related to new hrtimer
Description: 
I'm trying to upgrade from dahdi-linux-2.0.0 to dahdi-linux-2.1.0.3. I get
compile errors which seem to relater to the new hrtimer interface. I'm
running FC9 with kernel 2.6.27.9. See the output below:

I don't know enough about this to fix it, but I can test it if required

Thanks

The problem is an alsa-patch in current fedora kernels that backports those
hrtimer accessors.

The attached patch detects if those functions are already defined in the
kernels hrtimer.h and conditinally adds them if necessary.
