* sysdeps/unix/sysv/linux/ia64/clone2.S (__clone2): Add support for
NPTL where the PID is stored at userlevel and needs to be reset when CLONE_THREAD is not used. nptl/ * sysdeps/ia64/tcb-offsets.sym (TID): Add. * sysdeps/unix/sysv/linux/ia64/clone2.S: New file. * Makefile (tests): Add tst-getpid2.c. * tst-getpid1.c (TEST_CLONE_FLAGS): Define. (do_test): Use it. Use __clone2 instead of clone on ia64. * tst-getpid2.c: New test.
