* sysdeps/generic/utmp_file.c (UNLOCK_FILE): Clear alarm before

	resetting handler, to avoid the possibility of a spurious SIGALRM
	delivered to the user's handler.
	Reported by Amit D. Chaudhary <amitc@brocade.com>,

	* misc/Makefile (CFLAGS-init-misc.c): Varaible removed.  It served to
	set -fkeep-inline-functions, which is not needed for the current file.

	* sysdeps/generic/ldsodefs.h: Add attribute_hidden to *_internal decls.
	(_dl_setup_hash): Add attribute_hidden.
	(_dl_sysdep_start, _dl_sysdep_start_cleanup): Likewise.
	(_dl_sysdep_read_whole_file, _dl_dprintf): Likewise.
	(_dl_new_object, _dl_map_object_deps): Likewise.
	(_dl_map_object_deps_internal): Remove decl.
	* elf/rtld.c (__mempcpy, _exit): Redeclare locally as hidden.

	* sysdeps/i386/dl-machine.h [PI_STATIC_AND_HIDDEN
	&& HAVE_VISIBILITY_ATTRIBUTE && HAVE_HIDDEN
	&& !HAVE_BROKEN_VISIBILITY_ATTRIBUTE]
	(elf_machine_dynamic, elf_machine_load_address): Rewritten without asm,
	instead relying on the compiler to produce only GOTOFF variable refs.
