commit 38acf35697c1bca396dedf7139995e6d0d4dd117
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Wed Jan 6 11:28:04 2016 -0800

    Mark ld.so internal mmap functions hidden in ld.so

    Since ld.so internal mmap functions are only used internally in ld.so,
    they can be made hidden.  Don't hide __mmap on Hurd, since __mmap in
    ld.so will be preempted by the one in libc.so after bootstrap.

         [BZ #19122]
         * include/sys/mman.h [IS_IN (rtld)]: Include <dl-mman.h>.
         * sysdeps/generic/dl-mman.h: New file.
         * sysdeps/mach/hurd/dl-mman.h: Likewise.
