+Subject: LoongArch: Include KBUILD_CPPFLAGS in CHECKFLAGS invocation
+
+From: WANG Xuerui <git@xen0n.name>
+
+commit 5ddc7a3794ddd3470635ebd325fa1dffea5b18c0 upstream.
+
+This is a port of commit 08f6554ff90e ("mips: Include KBUILD_CPPFLAGS in
+CHECKFLAGS invocation") to arch/loongarch, for fixing cross-compilation
+of Linux/LoongArch with Clang, where previously the `--target` flag
+would no longer be present for the CHECKFLAGS cc invocation leading to
+build failure.
