[Devel] [PATCH RH8] mm: Fix section mismatch of zero_free_pages

[Kirill Tkhai]

zero_free_pages is used not only from boot code:

WARNING: vmlinux.o(.text+0x21f668): Section mismatch in reference from the function __free_pages_ok() to the variable .init.data:zero_free_pages
The function __free_pages_ok() references
the variable __initdata zero_free_pages.
This is often because __free_pages_ok lacks a __initdata
annotation or the annotation of zero_free_pages is wrong.
