BugLink: http://bugs.launchpad.net/bugs/968233 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.
