From: Masahiro Yamada <masahiroy@xxxxxxxxxx> [ Upstream commit 1b620d539ccc18a1aca1613d9ff078115a7891a1 ] Previously 'make ARCH=um headers' stopped because of missing arch/um/include/uapi/asm/Kbuild. The error is not shown since commit ed102bf2afed ("um: Fix W=1 missing-include-dirs warnings") added arch/um/include/uapi/asm/Kbuild. Hard-code the unsupported architecture, so it works like before.
