* pthread.c: Correct long-time braino. We never set SA_SIGINFO and
therefore don't need the _rt versions of the signal handlers.
* internals.h: Declare __pthread_yield.
* elf/dl-version.c (_dl_check_map_versions): New argument trace_mode.
Before testing versions check that we actually loaded the object
and whether we are in trace mode. If not loaded during tracing don't
test versions in this object.
(_dl_check_all_versions): Take new parameter and pass to
_dl_check_map_versions.
* sysdeps/generic/ldsodefs.h: Update prototypes for
_dl_check_all_versions and _dl_check_map_versions.
* elf/rtld.c (struct version_check_args): Add dotrace.
(version_check_doit): Pass args->dotrace to _dl_check_all_versions.
(dl_main): Pass info about trace mode to version_check_doit.
* elf/dl-open.c (dl_open_worker): Pass zero as new argument to
_dl_check_all_versions.
* manual/users.texi (XPG Functions): Document utmpxname, getutmp,
and getutmpx.
Patch by Bryan Henderson <bryanh@giraffe-data.com>.
