OK, this breaks the ia64 build because of the following... /drivers/firmware/efi/libstub/efi-stub-helper.c:14:21: fatal error: asm/efi.h: No such file or directory > diff --git a/drivers/firmware/efi/Makefile b/drivers/firmware/efi/Makefile > index e1096539eedb..d9abdbc962f1 100644 > --- a/drivers/firmware/efi/Makefile > +++ b/drivers/firmware/efi/Makefile > @@ -1,7 +1,7 @@ > # > # Makefile for linux kernel > # > -obj-$(CONFIG_EFI) += efi.o vars.o > +obj-$(CONFIG_EFI) += efi.o vars.o libstub/ > obj-$(CONFIG_EFI_VARS) += efivars.o > obj-$(CONFIG_EFI_VARS_PSTORE) += efi-pstore.o > obj-$(CONFIG_UEFI_CPER) += cper.o I guess what we need is CONFIG_EFI_LIBSTUB selected by both CONFIG_EFI_STUB (for x86) and CONFIG_EFI_ARMSTUB (for arm64)? e.g. obj-$(CONFIG_EFI_LIBSTUB) libstub/ -- Matt Fleming, Intel Open Source Technology Center -- To unsubscribe from this list: send the line "unsubscribe linux-efi" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
