      [ARM] allow for alternative __copy_to_user/__clear_user implementations · a1f98849
      Nicolas Pitre 提交于
      This allows for optional alternative implementations of __copy_to_user
      and __clear_user, with a possible runtime fallback to the standard
      version when the alternative provides no gain over that standard
      version. This is done by making the standard __copy_to_user into a weak
      alias for the symbol __copy_to_user_std.  Same thing for __clear_user.
      
      Those two functions are particularly good candidates to have alternative
      implementations for, since they rely on the STRT instruction which has
      lower performances than STM instructions on some CPU cores such as
      the ARM1176 and Marvell Feroceon.
