* sysdeps/mach/alpha/syscall.S: Don't use .frame, ENTRY will have it; 

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.
