[RFC PATCH 02/35] Makefile support to build Xen subarch

[Chris Wright <chrisw@sous-sol.org>]

[-- Attachment #1: 01-i386-mach-xen --]
[-- Type: text/plain, Size: 1323 bytes --]

Use arch/i386/mach-xen when building Xen subarch. The separate
subarchitecture allows us to hide details of interfacing with the
hypervisor from i386 common code.
