    x86, ia32_aout: do not kill argument mapping · 318f6b22
    Jiri Slaby authored
    Do not set current->mm->mmap to NULL in 32-bit emulation on 64-bit
    load_aout_binary after flush_old_exec as it would destroy already
    set brpm mapping with arguments.
    
    Introduced by b6a2fea3
    mm: variable length argument support
    where the argument mapping in bprm was added.
    
    [ hpa: this is a regression from 2.6.22... time to kill a.out? ]
