+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.
