* elf/tst-tls-dlinfo.c: New file.
	* elf/Makefile (tests): Add it.
	($(objpfx)tst-tls-dlinfo): Depend on $(libdl).
	($(objpfx)tst-tls-dlinfo.out): Depend on $(objpfx)tst-tlsmod2.so.

	* dlfcn/dlfcn.h (RTLD_DI_PROFILENAME, RTLD_DI_PROFILEOUT): New enum
	values, reserve unsupported requested names used on Solaris.
	(RTLD_DI_TLS_MODID, RTLD_DI_TLS_DATA): New enum values.
	(RTLD_DI_MAX): Likewise.
	* dlfcn/dlinfo.c (dlinfo_doit): Handle RTLD_DI_TLS_MODID and
	RTLD_DI_TLS_DATA.

	* elf/dl-tls.c (_dl_tls_get_addr_soft): New function.
	* sysdeps/generic/ldsodefs.h: Declare it.
	* elf/Versions (ld: GLIBC_PRIVATE): Add it.
	* elf/link.h (struct dl_phdr_info): New members dlpi_tls_modid,
	dlpi_tls_data.
	* elf/dl-iteratephdr.c (__dl_iterate_phdr): Fill them in.

	* include/link.h: Don't copy contents from elf/link.h.
	Instead, #include it while #define'ing around link_map.
	* elf/dl-debug.c (_dl_debug_initialize): Add a cast.
	Add bogus extern decl to verify link_map members.
	* elf/loadtest.c (MAPS): New macro, cast _r_debug._r_map.
	(OUT, main): Use it in place of _r_debug._r_map.
