Currently symbols that are absolute addresses are incorrectly displayed
in /proc/kallsyms if the kernel is loaded with kASLR.

The problem was that the scripts/kallsyms.c file which generates the
array of symbol names and addresses uses an relocatable value for all
symbols, even absolute symbols.  This patch fixes that.

Several kallsyms output in different boot states for comparison:

  $ egrep '_(stext|_per_cpu_(start|end))' /root/kallsyms.nokaslr
  0000000000000000 D __per_cpu_start

LZ4 as implemented in the kernel differs from the default method now
used by the reference implementation of LZ4.  Until the in-kernel method
is updated to support the new default, passing the legacy flag (-l) to
the compressor is necessary.  Without this flag the kernel-generated,
LZ4-compressed initramfs is junk.

The testcase data is usable by any platform. This patch moves it into
the drivers/of directory so it can be included by any architecture.

Using the test cases requires manually adding #include <testcases.dtsi>

pretty though. A useful project would be to make the testcase code

Commit afe2dab4 ("USB: add hex/bcd detection to usb modalias generation")
changed the routine that generates alias ranges. Before that change, only
digits 0-9 were supported; the commit tried to fix the case when the range
includes higher values than 0x9.

Unfortunately, the commit didn't fix the case when the range includes both
0x9 and 0xA, meaning that the final range must look like [x-9A-y] where
x <= 0x9 and y >= 0xA -- instead the [x-9A-x] range was produced.

Modprobe doesn't complain as it sees no difference between no-match and
bad-pattern results of fnmatch().

Fixing this simple bug to fix the aliases.
Also changing the hardcoded beginning of the range to uppercase as all the
other letters are also uppercase in the device version numbers.

Fortunately, this affects only the dvb-usb-dib0700 module, AFAIK.

This change restricts the check for the for the FSF address in the GPL
copyright statement so that it only flags the address, not the
references to the gnu.org/licenses URL which appears to be used in
numerous drivers.  The idea is to still allow some reference to an
external copy of the GPL in the event that files are copied out of the
kernel tree without the COPYING file.

So for example this statement will still return an error:
  You should have received a copy of the GNU General Public License
  along with this program; if not, write to the Free Software
  Foundation, Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.

switch case statements missing a break statement are an unfortunately
common error.

e.g.:
  commit 4a2c94c9 ("HID: kye: Add report fixup for Genius Manticore Keyboard")

case blocks should end in a break/return/goto/continue.

If a fall-through is used, it should have a comment showing that it is
intentional.  Ideally that comment should be something like:
"/* fall-through */"

Add a test to look for missing break statements.

This looks only at the context lines before an inserted case so it's
possible to have false positives when the context contains a close brace
and the break is before the brace and not part of the patch context.

Looking at recent patches, this is a pretty rare occurrence.  The normal
kernel style uses a break as the last line of the previous block.

"make headers_check" warns about soundcard.h for (at least) five years
now:
    [...]/usr/include/linux/soundcard.h:1054: userspace cannot reference function or variable defined in the kernel

We're apparently stuck with providing OSSlib-3.8 compatibility, so let's
special case this declaration just to silence it.

Notes:

0) Support for OSSlib post 3.8 was already removed in commit 43a99076
   ("sound: Remove OSSlib stuff from linux/soundcard.h").  Five years have
   passed since that commit: do people still care about OSSlib-3.8?  If
   not, quite a bit of code could be remove from soundcard.h (and probably
   ultrasound.h).

2) By the way, what is actually meant by:
    It is no longer possible to actually link against OSSlib with this
    header, but we still provide these macros for programs using them.

Doesn't that mean compatibility to OSSlib isn't even useful?

3) Anyhow, a previous discussion soundcard.h, which led to that commit,
   starts at https://lkml.org/lkml/2009/1/20/349 .

4) And, yes, I sneaked in a whitespace fix.

The kernel postinst hook for initramfs-tools will build an initramfs
on installation unless $INITRD is set to 'No'.  make-kpkg generates a
postinst script that sets this variable appropriately, but we don't.
Set it based on CONFIG_BLK_DEV_INITRD.

This should also work with dracut when <http://bugs.debian.org/729622>
is fixed.

This reverts commits
f3462aa9 (Kbuild: Handle longer symbols in kallsyms.c) and
eea0e9cb (kbuild: Increase kallsyms max symbol length)
except for the added overflow check. The reason is a regression caused
by increasing the buffer:

When using '!Ffile function' in a docbook template, and the function no
longer exists, you get a "no structured comments found" error from the
kernel-doc processing script.  It's useful to know which functions it was
looking for, so print them out in this case.  Also do the same for '!Pfile
doc-section'

The same error also happens when using '!Efile' when some exported
functions aren't documented (in the same file.) There's a very large
number of such functions though, so don't print the message in this case
-- right now it would give ~850 messages.
