From fc6543bb55d4077c44e577c321bbf158446c8000 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Sat, 28 Oct 2023 20:34:53 +0100 Subject: KVM: selftests: add -MP to CFLAGS Using -MD without -MP causes build failures when a header file is deleted or moved. With -MP, the compiler will emit phony targets for the header files it lists as dependencies, and the Makefiles won't refuse to attempt to rebuild a C unit which no longer includes the deleted header.
