What release of sparse would that be?  Fedora ships one tagged as 0.4.1-2.fc9,
but that says:

include/linux/kernel.h:135:52: error: attribute '__cold__': unknown attribute

But you go look at Documentation/sparse.txt and it points you to:

"You can get latest released versions from the Sparse homepage at
http://www.kernel.org/pub/linux/kernel/people/josh/sparse/ "

which says 0.4.1 is the latest released version.  So is this a git-only feature?
