Subject: mm/sparse: move __section_mark_present() to internal.h
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=08e5f77c37206da5a8340afdbf23b61e722c0ed3;p=thirdparty%2Fkernel%2Flinux.git

mm/sparse: move __section_mark_present() to internal.h

Let's prepare for moving memory hotplug handling from sparse.c to
sparse-vmemmap.c by moving __section_mark_present() to internal.h.
