[Andrew Morton <akpm@linux-foundation.org>]

The patch titled
     Subject: mm/vmalloc: add DEFINE_FREE() for vfree()
has been added to the -mm mm-new branch.  Its filename is
     mm-vmalloc-add-define_free-for-vfree.patch

This patch will shortly appear at
     https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/mm-vmalloc-add-define_free-for-vfree.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
