On Linux the definitions and functions are not only NPTL related, but used for other POSIX definitions as well (for instance SIGTIMER for posix times, SIGSETXID for id functions, and signal block/restore helpers) and since generic functions will be places and used in generic implementation it makes more sense to decouple it from NPTL. Checked on x86_64-linux-gnu. * sysdeps/nptl/nptl-signals.h: Move to ... * sysdeps/generic/internal-signals.h: ... here. Adjust internal comments. * sysdeps/unix/sysv/linux/internal-signals.h: Add include guards. (__nptl_is_internal_signal): Rename to __is_internal_signal. (__nptl_clear_internal_signals): Rename to __clear_internal_signals. * sysdeps/unix/sysv/linux/raise.c: Adjust nptl-signal.h to include-signals.h rename. * nptl/pthreadP.h: Likewise. * sysdeps/unix/sysv/linux/spawni.c (__spawni_child): Call __is_internal_signal instead of __nptl_is_internal_signal.
