* sysdeps/generic/thread_state.h (MACHINE_NEW_THREAD_STATE_FLAVOR): Define macro. * sysdeps/mach/thread_state.h (MACHINE_THREAD_STATE_FIX_NEW): New macro. * sysdeps/mach/i386/thread_state.h (MACHINE_NEW_THREAD_STATE_FLAVOR): New macro, defined to i386_THREAD_STATE. (MACHINE_THREAD_STATE_FLAVOR): Define to i386_REGS_SEGS_STATE instead of i386_THREAD_STATE. (MACHINE_THREAD_STATE_FIX_NEW): New macro, reads segments. * sysdeps/mach/hurd/i386/trampoline.c (_hurd_setup_sighandler): Use i386_REGS_SEGS_STATE instead of i386_THREAD_STATE. * sysdeps/mach/hurd/i386/tls.h (TCB_ALIGNMENT, HURD_SEL_LDT): New macros. (_hurd_tls_fork): Add original thread parameter, Duplicate existing LDT descriptor instead of creating a new one. (_hurd_tls_new): New function, creates a new descriptor and updates tcb. * mach/setup-thread.c: Include <ldsodefs.h>. (__mach_setup_thread): Call _dl_allocate_tls, pass MACHINE_NEW_THREAD_STATE_FLAVOR to __thread_set_state instead of MACHINE_THREAD_STATE_FLAVOR, before getting MACHINE_THREAD_STATE_FLAVOR, calling _hurd_tls_new, and setting MACHINE_THREAD_STATE_FLAVOR with the result. * hurd/hurdfault.c (_hurdsig_fault_init): Call MACHINE_THREAD_STATE_FIX_NEW. * sysdeps/mach/hurd/fork.c (__fork): Call _hurd_tls_fork for sigthread too. Add original thread parameter.
