I recently putback a change to install in xen/sys/* on Linux too. I
think this will need to be a configure test at some point, to support
older Xens. That is:

older Xen on Linux: linux/privcmd.h
newer Xen on Linux: sys/privcmd.h
Xen on Solaris: sys/privcmd.h

Actually the dom0 kernel does this.

In terms of cpuid, it works on Linux too, except that Linux has
/dev/cpu/0/cpuid and we have /dev/cpu/self/cpuid. Also I don't think you
can rely on the Linux driver being available.
