    x86: Remove __memset_zero_constant_len_parameter [BZ #21790]
    
    __memset_zero_constant_len_parameter should be removed by
    
    commit 61062f56304750c367c5c1533351621353c112a7

                * debug/Versions (libc: GLIBC_2.4): Remove
                __memset_zero_constant_len_parameter.
                * sysdeps/generic/memset_chk.c: Remove alias and warning.
                * misc/sys/cdefs.h (__warndecl): New macro.
                * debug/warning-nop.c: New file.
                * string/bits/string3.h (memset): Call __warn_memset_zero_len with no
                arguments, instead of calling __memset_zero_constant_len_parameter.
                Use __warndecl for __warn_memset_zero_len.
                * debug/Makefile (routines): Add $(static-only-routines).
                (static-only-routines): New variable.
    
    This patch removes the last emaining pieces of it.  Tested it on i586,
    i686 and x86-64.

    	* sysdeps/i386/i586/memset.S
