From 38acf35697c1bca396dedf7139995e6d0d4dd117 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Wed, 6 Jan 2016 11:28:04 -0800 Subject: 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.
