The patch titled
mm: enable set_page_section() only if CONFIG_SPARSEMEM and !CONFIG_SPARSEMEM_VMEMMAP
has been removed from the -mm tree. Its filename was
mm-enable-set_page_section-only-if-config_sparsemem-and-config_sparsemem_vmemmap.patch
This patch was dropped because it was merged into mainline or a subsystem tree

Subject: mm: enable set_page_section() only if CONFIG_SPARSEMEM and !CONFIG_SPARSEMEM_VMEMMAP
From: Daniel Kiper <dkiper@xxxxxxxxxxxx>
set_page_section() is meaningful only in CONFIG_SPARSEMEM and
!CONFIG_SPARSEMEM_VMEMMAP context. Move it to proper place and amend
accordingly functions which are using it.
