+ mm-sparse-correct-init-section-annotations.patch added to mm-new branch

The patch titled
     Subject: mm/sparse: correct init section annotations
has been added to the -mm mm-new branch.  Its filename is
     mm-sparse-correct-init-section-annotations.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-sparse-correct-init-section-annotations.patch

This patch will later appear in the mm-new branch at
    git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Note, mm-new is a provisional staging ground for work-in-progress
patches, and acceptance into mm-new is a notification for others take
notice and to finish up reviews.  Please do not hesitate to respond to
review feedback and post updated versions to replace or incrementally
fixup patches in mm-new.

The mm-new branch of mm.git is not included in linux-next

If a few days of testing in mm-new is successful, the patch will me moved
into mm.git's mm-unstable branch, which is included in linux-next

   a) Consider who else should be cc'ed
   b) Prefer to cc a suitable mailing list as well
   c) Ideally: find the original patch on the mailing list and do a
      reply-to-all to that, adding suitable additional cc's

*** Remember to use Documentation/process/submit-checklist.rst when testing your code ***

The -mm tree is included into linux-next via various
branches at git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

The !SPARSEMEM_EXTREME stub of sparse_index_init() has no annotation but
the SPARSEMEM_EXTREME variant is __meminit.  So mark the stub __meminit
too.

mminit_validate_memmodel_limits() is only called by memory_present(),
which is __init.  So mark it __init.

sparse_usagebuf and sparse_usagebuf_end are only used by
sparse_init_early_section(), sparse_usage_init() and sparse_usage_fini(),
which are all __init.  So mark them __initdata.
