Commit 1b6740a1 was marked as stable but conflicts with 93068241.
This patch resolves the conflict so that an OProfile-enabled ARM kernel can be used.

Nicolas - this patch fixes an unresolved merge conflict present in the Linaro 2.6.35-stable tree which results in build failure if oprofile is enabled. The resolution isn't especially trivial but I think I've got it right.
