use END macro instead of our own .end directive. Use `callsys' insn mnemonic instead of `call_pal'. * sysdeps/mach/alpha/sysdep.h (ENTRY): New macro. * sysdeps/alpha/dl-machine.h (ELF_MACHINE_USER_ADDRESS_MASK): New macro; we need this for Hurd. Log entry was missing for 2002/03/24 commit of rev 1.8, goes with 2002-03-17 changes. * sysdeps/mach/hurd/i386/Makefile [$(subdir) = misc] (sysdep_routines): Append ioperm here. (sysdep_headers): Append sys/io.h here.
