hurd: add TLS support
* 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.
