From: Arnd Bergmann <arnd@xxxxxxxx>
Subject: mm: meminit: mark init_reserved_page as __meminit
The function is called from __meminit context and calls other __meminit
functions but isn't it self mark as such today:
WARNING: vmlinux.o(.text.unlikely+0x4516): Section mismatch in reference from the function init_reserved_page() to the function .meminit.text:early_pfn_to_nid()
The function init_reserved_page() references
the function __meminit early_pfn_to_nid().
This is often because init_reserved_page lacks a __meminit
annotation or the annotation of early_pfn_to_nid is wrong.
On most compilers, we don't notice this because the function gets inlined
all the time. Adding __meminit here fixes the harmless warning for the
old versions and is generally the correct annotation.
