I bisected it down to my merge of the tip tree (commit 26b38c5887 in
next-20120522).  I only enable GENERIC_CLOCKEVENTS for sparc64 - I missed
a subtle interaction between commit 62f082830d63 ("sparc32: generic
clockevent support") from the sparc-next tree and commit ded1cc5cfc3b
("sparc: Use: generic time config") from the tip tree.

I will fix this up in linux-next today.  Sorry for the noise.
