$(error) would break compiling via tools/testing/selftests/Makefile, so 
I am squashing this:

diff --git a/tools/testing/selftests/kvm/Makefile 
b/tools/testing/selftests/kvm/Makefile
index d761a77c3a80..59f3eb53c932 100644
--- a/tools/testing/selftests/kvm/Makefile
+++ b/tools/testing/selftests/kvm/Makefile
@@ -13,10 +13,8 @@ else ifeq ($(ARCH),arm64)
 	ARCH_DIR := aarch64
 else ifeq ($(ARCH),s390)
 	ARCH_DIR := s390x
-else ifeq ($(ARCH),riscv)
-	ARCH_DIR := riscv
 else
-$(error Unknown architecture '$(ARCH)')
+	ARCH_DIR := $(ARCH)
 endif

 LIBKVM += lib/assert.c

Then the aarch64 and s390x directories can be renamed---x86 too, but the 
ifeq needs to stay (just changed to do x86_64->x86 instead of the other 
way round).
