* elf/dl-lookup.c (_dl_debug_bindings): Remove unised symbol_scope
argument. (_dl_lookup_symbol_x): Adjust caller. * sysdeps/generic/ldsodefs.h (struct link_namespaces): Remove _ns_global_scope. * elf/rtld.c (dl_main): Don't initialize _ns_global_scope. * elf/dl-libc.c: Revert l_scope name changes. * elf/dl-load.c: Likewise. * elf/dl-object.c: Likewise. * elf/rtld.c: Likewise. * elf/dl-close.c (_dl_close): Likewise. * elf/dl-open.c (dl_open_worker): Likewise. If not SINGLE_THREAD_P, always use __rtld_mrlock_{change,done}. Always free old scope list here if not l_scope_mem. * elf/dl-runtime.c (_dl_fixup, _dl_profile_fixup): Revert l_scope name change. Never free scope list here. Just __rtld_mrlock_lock before the lookup and __rtld_mrlock_unlock it after the lookup. * elf/dl-sym.c: Likewise. * include/link.h (struct r_scoperec): Remove. (struct link_map): Replace l_scoperec with l_scope, l_scoperec_mem with l_scope_mem and l_scoperec_lock with l_scope_lock.
