Ah... sorry, I forgot about the base tree.  The definition has been in
the percpu tree for some time now.  The patchset is on top of the
following branch.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git for-next

and the series is available as git tree in the following branch.

  git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu.git percpu-sparse-review

The definition is in include/linux/compiler.h.

# define __percpu	__attribute__((noderef, address_space(3)))

which gets replaced by dummy def if !__CHECKER__.

Thanks.
