+
+	* sysdeps/unix/sysv/linux/mips/getrlimit64.c: On O32 and N32 ABIs,
+	include the generic getrlimit64 version as __internal_getrlimit64
+	and add a wrapper around it to convert the RLIM64_INFINITY constant
+	between the libc and the kernel version.
+	* sysdeps/unix/sysv/linux/mips/setrlimit64.c: Ditto with setrlimit64.

 	* sysdeps/unix/sysv/linux/mips/bits/ipc.h: Use __glibc_reserved instead __unused.
 	* sysdeps/unix/sysv/linux/mips/bits/msq.h: Likewise.
