ftrace: Build with CPPFLAGS to get -Qunused-arguments

2018-09-19T14:53:54Z

When building to record the mcount locations the kernel uses KBUILD_CFLAGS but not KBUILD_CPPFLAGS. This means it lacks -Qunused-arguments when building with clang, resulting in a lot of noisy warnings. Signed-off-by: Joel Stanley Reviewed-by: Nick Desaulniers Signed-off-by: Masahiro Yamada

kbuild: modules_install: warn when missing System.map file

2018-09-09T00:14:07Z

If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.

selftests: add headers_install to lib.mk

2018-09-05T14:12:09Z

If the kernel headers aren't installed we can't build all the tests. Add a new make target rule 'khdr' in the file lib.mk to generate the kernel headers and that gets include for every test-dir Makefile that includes lib.mk If the testdir in turn have its own sub-dirs the top_srcdir needs to be set to the linux-rootdir to be able to generate the kernel headers.

checkpatch: add __ro_after_init to known $Attribute

2018-09-04T23:45:02Z

__ro_after_init is a specific __attribute__ that checkpatch does currently not understand. Add it to the known $Attribute types so that code that uses variables declared with __ro_after_init are not thought to be a modifier type. This appears as a defect in checkpatch output of code like: static bool trust_cpu __ro_after_init = IS_ENABLED(CONFIG_RANDOM_TRUST_CPU); [...] if (trust_cpu && arch_init) { where checkpatch reports: ERROR: space prohibited after that '&&' (ctx:WxW) if (trust_cpu && arch_init) { Link: http://lkml.kernel.org/r/0fa8a2cb83ade4c525e18261ecf6cfede3015983.camel@perches.com Signed-off-by: Joe Perches Reported-by: Kees Cook Tested-by: Kees Cook Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
