* 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.
