From e847f6aaf68f6156a5e9b26afe1a7316b9ab697e Mon Sep 17 00:00:00 2001 From: Sven Wegener Date: Sat, 24 Mar 2018 22:21:13 +0100 Subject: x86/purgatory: Avoid creating stray ..d files, remove -MD from KBUILD_CFLAGS The kernel build system already takes care of generating the dependency files. Having the additional -MD in KBUILD_CFLAGS leads to stray ..d files in the build directory when we call the cc-option macro. Signed-off-by: Sven Wegener Cc: H.
