Subject: [PATCH] powerpc/mm: Fix section mismatch warning
remove_pte_table is only called from remove_pmd_table which is marked
__meminit. These functions are used only during memory hotplug and they
also call functions marked __meminit. Mark remove_pte_table also with
__meminit so that we can avoid the section mismatch warning below.
WARNING: modpost: vmlinux: section mismatch in reference:
remove_pte_table+0x230 (section: .text.remove_pte_table) -> free_vmemmap_pages
(section: .meminit.text)
WARNING: modpost: vmlinux: section mismatch in reference:
remove_pte_table+0x43c (section: .text.remove_pte_table) -> vmemmap_populated
(section: .meminit.text)
WARNING: modpost: vmlinux: section mismatch in reference:
remove_pte_table+0x4a4 (section: .text.remove_pte_table) -> free_vmemmap_pages
(section: .meminit.text)
