The thing is...

sys/sys/Makefile has this log message:

revision 1.68
date: 2004/10/10 08:57:30;  author: yamt;  state: Exp;  lines: +2 -2
don't install cpu_data.h or cc_microtime.h.
they're not intended to be exposed to userland.

I'm reluctant to reverse that decision if it's just alpha which
needs cpu_data.h to be installed.

I have tried various other types of re-arrangement of the alpha
cpu.h file, none of them successful -- it either falls over while
trying to build libkvm, vmstat or pstat.

I'm therefore asking for input as to the right course of action.
