That config doesn't build for me. When I put it in place and do "make oldconfig" it still asks for lots of config options (which I just set to default). But when I build it fails with:
CC arch/x86/kernel/asm-offsets.s In file included from include2/asm/page.h:40, from include2/asm/pda.h:8, from include2/asm/current.h:19, from include2/asm/processor.h:15, from /home/jeremy/hg/xen/paravirt/linux/include/linux/prefetch.h:14, from /home/jeremy/hg/xen/paravirt/linux/include/linux/list.h:6, from /home/jeremy/hg/xen/paravirt/linux/include/linux/module.h:9, from /home/jeremy/hg/xen/paravirt/linux/include/linux/crypto.h:21, from /home/jeremy/hg/xen/paravirt/linux/arch/x86/kernel/asm-offsets_64.c:7, from /home/jeremy/hg/xen/paravirt/linux/arch/x86/kernel/asm-offsets.c:4: include2/asm/page_64.h:46:2: error: #error "CONFIG_PHYSICAL_START must be a multiple of 2MB" make[3]: *** [arch/x86/kernel/asm-offsets.s] Error 1
I can fix that, of course, but it doesn't give me confidence I'm testing what you are...
