XEN modules?

[Paul Goyette <paul%whooppee.com@localhost>]

I know there's some magic somewhere in the Makefiles that automatically 
builds both "normal" and XEN variants of the modules for amd64 (and, for 
i386, there's a PAE variant, too)!  But I can't seem to find the magic!

Anyway, it seems to me that, when building the XEN (or PAE) variants of 
each module, they should be built with -DXEN (or -DPAE) options.  There 
is at least one source file, compiled into the compat module, which has 
some code conditional on XEN.  (For those who care, it is the compat_60 
x86 code for updating AMD cpu_ucode.)

Based on log files, we're currently not defining XEN or PAE for the 
modules builds.  As a result the XEN variant of the compat module does 
not contain the required code, preventing use of the 6.0 cpuctl command.

So,

1. Would it be reasonable to define the XEN and PAE macros when building
   the module variants?

2. What would it take to make it happen?

3. Where's the magic?  :)
