Cpu ID under UNIX

[Dave Abbajay]

The VAX hardware supports the ability of obtaining the CPU id. Under
VMS its obtained by the call to LIB$GETSYI. Has anyone done this
under UNIX. It is a priveleged instruction, therefore it probably
means a kernel hack or a device driver to get it (unless there
is another way for a user to execute in kernel mode that I'm
not aware of). Any help would be appreciated.

As an aside, wouldn't this be an appropriate discussion for,
say, mod.std.unix (or is it mod.unix.std). I'd like to see
a standard system call in UNIX for doing this (provided hardware
support, of course).
