	Are you referring to some out-of-tree architectures? I've
verified the string GENERIC_CLOCKEVENTS_MIGR is only appearing at this
single spot in kconfig and nowhere else in code/Kconfig in my
up-to-date linux tree.

	If not maybe I was a bit unclear about the actual rational
behind the code patch. As GENERIC_CLOCKEVENTS_MIGR is not selectable
GENERIC_CLOCKEVENTS_BUILD implies GENERIC_CLOCKEVENTS so inside a
GENERIC_CLOCKEVENTS_BUILD block a check for GENERIC_CLOCKEVENTS is
non-necessary for everything inside the linus tree and the else branch
unavailable. In this case I'll prepare an more complete patch as
suggested by CHristoph Hellwig tomorrow or friday.
