This way we do not need to call the kernel just to get the port. Furthermore, we no longer increase the reference count on every invocation of `mach_host_self'. * mach/mach/mach_traps.h (__mach_host_self, mach_host_self): Protect declarations against the macro expansion. * mach/mach_init.c (__mach_host_self_): New variable. (mach_init): Initialize `__mach_host_self_'. * mach/mach_init.h (__mach_host_self_): New declaration. (__mach_host_self, mach_host_self): New macros. * sysdeps/mach/hurd/dl-sysdep.c (_dl_sysdep_start_cleanup): Release reference.
