The arch Makefile may override the include path order, which is used by Xen (and UML?) to make sure include/asm-xen is searched before include/asm-i386. The Makefile change to 2.6.12-rc4 made the top Makefile always override the value specified by the arch Makefile. This trivial patch makes the Xen kernel compile again.

Also playing with NOSTDINC_FLAGS will most likely break builds with Osince kbuild does not mangle patchs specified with NOSTDINC Sam _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
