I already had

ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.24-rc4/2.6.24-rc4-mm1/broken-out/mm-sparsec-improve-the-error-handling-for-sparse_add_one_section.patch
and
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.24-rc4/2.6.24-rc4-mm1/broken-out/mm-sparsec-check-the-return-value-of-sparse_index_alloc.patch

queued.  Do they fix the problem, and should they be merged in 2.6.24?
