Roland McGrath a2f63c54dd * sysdeps/unix/sysv/linux/mips/bits/socket.h (__cmsg_nxthdr): Use
__NTH instead of __THROW in the inline definition.
	* sysdeps/unix/sysv/linux/mips/sys/tas.h (_test_and_set): Likewise.

	* sysdeps/mips/bits/dlfcn.h (RTLD_DEEPBIND): New macro.

	* sysdeps/unix/sysv/linux/mips/bits/mman.h
	(PROT_GROWSDOWN, PROT_GROWSUP): New macros.
