The patch titled
Subject: mm: meminit: initialise a subset of struct pages if CONFIG_DEFERRED_STRUCT_PAGE_INIT is set -fix
has been removed from the -mm tree. Its filename was
mm-meminit-initialise-a-subset-of-struct-pages-if-config_deferred_struct_page_init-is-set-fix.patch
This patch was dropped because it was folded into mm-meminit-initialise-a-subset-of-struct-pages-if-config_deferred_struct_page_init-is-set.patch

Subject: mm: meminit: initialise a subset of struct pages if CONFIG_DEFERRED_STRUCT_PAGE_INIT is set -fix
This is take 2 on describing why these section names exist. If accepted
then it should be considered a fix for the mmotm patch
mm-meminit-initialise-a-subset-of-struct-pages-if-config_deferred_struct_page_init-is-set.patch

- * Deferred struct page initialisation requires some early init functions that

+ * Deferred struct page initialisation requires init functions that are freed

+ * __defermem_init is code that always exists but is annotated __meminit to

+ * __defer_init code gets marked __meminit when deferring struct page
+ * initialistion but is otherwise in the init section.
