Subject: [PATCH] UBUNTU: SAUCE: disable_nx should not be in __cpuinitdata
section for X86_32
I noticed a section mismatch warning while building 3.2.0-20.33 for X86_32.
AR arch/x86/lib/lib.a
LD vmlinux.o
MODPOST vmlinux.o
WARNING: vmlinux.o(.text+0x187833): Section mismatch in reference from the function load_elf_binary() to the variable .cpuinit.data:disable_nx
The function load_elf_binary() references
the variable __cpuinitdata disable_nx.
This is often because load_elf_binary lacks a __cpuinitdata
annotation or the annotation of disable_nx is wrong.
load_elf_binary() is definitely called after initialization.
This code was added by 'UBUNTU: ubuntu: nx-emu - i386: NX emulation', so
this is not an upstream problem.
