      kbuild: rpm: prompt to use "rpm-pkg" if "rpm" target is used · ebaad7d3
      Masahiro Yamada authored 
      The "rpm" has been kept for backward compatibility since pre-git era.
I am planning to remove it after the Linux 4.18 release.  Annouce the
end of the support, prompting to use "rpm-pkg" instead.

If you use "rpm", it will work like "rpm-pkg", but warning messages
will be displayed as follows:

  WARNING: "rpm" target will be removed after Linux 4.18
           Please use "rpm-pkg" instead.

      kbuild: pkg: use --transform option to prefix paths in tar · 2dbc644a
      Masahiro Yamada authored 
      For rpm-pkg and deb-pkg, a source tar file is created.  All paths in
the archive must be prefixed with the base name of the tar so that
everything is contained in the directory when you extract it.

Currently, scripts/package/Makefile uses a symlink for that, and
removes it after the tar is created.

If you terminate the build during the tar creation, the symlink is
left over.  Then, at the next package build, you will see a warning
like follows:

  ln: '.' and 'kernel-4.14.0+/.' are the same file

It is possible to fix it by adding -n (--no-dereference) option to
the "ln" command, but a cleaner way is to use --transform option
of "tar" command.  This option is GNU extension, but it should not
hurt to use it in the Linux build system.

The 'S' flag is needed to exclude symlinks from the path fixup.
Without it, symlinks in the kernel are broken.

      coccinelle: fix parallel build with CHECK=scripts/coccicheck · d7059ca0
      Masahiro Yamada authored 
      The command "make -j8 C=1 CHECK=scripts/coccicheck" produces
lots of "coccicheck failed" error messages.

Julia Lawall explained the Coccinelle behavior as follows:
"The problem on the Coccinelle side is that it uses a subdirectory
with the name of the semantic patch to store standard output and
standard error for the different threads.  I didn't want to use a
name with the pid, so that one could easily find this information
while Coccinelle is running.  Normally the subdirectory is cleaned
up when Coccinelle completes, so there is only one of them at a time.
Maybe it is best to just add the pid.  There is the risk that these
subdirectories will accumulate if Coccinelle crashes in a way such
that they don't get cleaned up, but Coccinelle could print a warning
if it detects this case, rather than failing."

When scripts/coccicheck is used as CHECK tool and -j option is given
to Make, the whole of build process runs in parallel.  So, multiple
processes try to get access to the same subdirectory.

I notice spatch creates the subdirectory only when it runs in parallel
(i.e. --jobs <N> is given and <N> is greater than 1).

Setting NPROC=1 is a reasonable solution; spatch does not create the
subdirectory.  Besides, ONLINE=1 mode takes a single file input for
each spatch invocation, so there is no reason to parallelize it in
the first place.

      kconfig/symbol.c: use correct pointer type argument for sizeof · 88127dae
      Heinrich Schuchardt authored 
      sym_arr is of type struct symbol **.
So in malloc we need sizeof(struct symbol *).

The problem was indicated by coccinelle.

      kbuild: Set KBUILD_CFLAGS before incl. arch Makefile · ae6b289a
      Chris Fries authored 
      Set the clang KBUILD_CFLAGS up before including arch/ Makefiles,
so that ld-options (etc.) can work correctly.

This fixes errors with clang such as ld-options trying to CC
against your host architecture, but LD trying to link against
your target architecture.
