FC6: Missing UTS_RELEASE from linux/version.h

[William John Murray <w j murray rl ac uk>]

  Hello guys,
              AFS compilation failed for kernel 2488 because UTS_RELEASE
was not defined in
/lib/modules/`uname- r`/build/include/linux/version.h

I added it by hand and it seems to be compiling until:

Entering directory `/usr/src/kernels/2.6.17-1.2488.fc6-i686'
Makefile:452: *** kernel configuration not valid - run 'make prepare' in 
/usr/src/kernels/2.6.17-1.2488.fc6-i686 to update it.  Stop.

Is this kernel broken,  or has something changed AFS needs to know about?
    Thanks,
          Bill
