    SubjectRe: [PATCH] ARM: Do not allow unaligned accesses when CONFIG_ALIGNMENT_TRAP

    It won't, the arm gcc code just checks flag_conserve_stack.
    IMHO it's just a gcc bug. You should report it to
    http://gcc.gnu.org/bugzilla

    As a temporary workaround you can disable it in the kernel too, but as soon
    as the compiler it's fixed I would recommend considering to reenable it.
