    riscv: fix compile failure with EXPORT_SYMBOL() & !MMU · 4d47ce15
    Luc Van Oostenryck authored
    When support for !MMU was added, the declaration of
    __asm_copy_to_user() & __asm_copy_from_user() were #ifdefed
    out hence their EXPORT_SYMBOL() give an error message like:
      .../riscv_ksyms.c:13:15: error: '__asm_copy_to_user' undeclared here
      .../riscv_ksyms.c:14:15: error: '__asm_copy_from_user' undeclared here
    
    Since these symbols are not defined with !MMU it's wrong to export them.
    Same for __clear_user() (even though this one is also declared in
    include/asm-generic/uaccess.h and thus doesn't give an error message).
    
    Fix this by doing the EXPORT_SYMBOL() directly where these symbols
    are defined: inside lib/uaccess.S itself.
