    uaccess: remove CONFIG_SET_FS · 967747bb
    Arnd Bergmann authored
    There are no remaining callers of set_fs(), so CONFIG_SET_FS
    can be removed globally, along with the thread_info field and
    any references to it.
    
    This turns access_ok() into a cheaper check against TASK_SIZE_MAX.
    
    As CONFIG_SET_FS is now gone, drop all remaining references to
    set_fs()/get_fs(), mm_segment_t, user_addr_max() and uaccess_kernel().
