This patch is fixing compile error on ARCH=SPARC and SPARC64:
Building sparc64:allmodconfig ... failed

The problem solved by this patch has affected linux-next
for almost a month, the problem is now in mainline, yet
I have not seen feedback from anyone about it.
Did the patch get lost, or is there some problem with it ?
Hi Guenter, Oleksij,
so I reviewed the patch more in detail.
The sparc/sparc64 configuration shouldn't select this timer.
What do you think about the following patch ?
