If CONIFIG_LOCALVERSION is set for example to -loop, the following error
message was generated.
dpkg-deb - error: Debian revision (`loop') doesn't contain any digits
dpkg-deb: 1 errors in control file
The patch solves this by adding a numeric revision to package version.

This version brings a large number of fixes which have built up over
the Christmas period. Mostly these are fixes for false positives, both
through improvments to unary checks and possible type detection. It
also brings new checks for while location and CVS keywords. Of note:
- a number of fixes to unary detection
- detection of a number of new forms of types to improve type matching
- better inline handling
- recognision of '%' as an operator
Andy Whitcroft (28):
Version: 0.13
unary detection: maintain bracket state across lines
move to pre-sanitising the entire file
the text of a #error statement should be treated like it is in quotes
line sanitisation needs to target double backslash correctly
tighten comment guestimation for lines starting ' * '
debug: add a debug framework
prevent unclosed single quotes from spreading
add % as an operator
the text of a #warning statement should be treated like it is in quotes
possible matching applies in typedefs
single statement block checks must not trigger when two or more statements
possible types: local variables may also be const
treat inline as a type attribute to even when out of place
possible types: sparse annotations are valid indicators
possible types: beef up the possible type testing
check for hanging while statements on the wrong line
utf8 checks need to occur against the raw lines
function brace checks should use any whitespece matches
comments should take up space in the line when sanitised
remove debugging from if assignment checks
possible types -- ensure we detect all pointer casts
fix tests for function spacing in the presence of #define
clean up the UTF-8 error message to be clearer
test-lib: invert the status report, output success counts
detect and report CVS keywords
tests: break out tests
Add $Id$ to the CVS keyword checks

When resolving symbol names from addresses with aliased symbol names,
kallsyms_lookup always returns the first symbol, even if it is a weak
symbol.
This patch changes this by sorting the symbols with the weak symbols last
before feeding them to the kernel. This way the kernel runtime isn't
changed at all, only the kallsyms build system is changed.
Another side effect is that the symbols get sorted by address, too. So,
even if future binutils version have some bug in "nm" that makes it fail to
correctly sort symbols by address, the kernel won't be affected by this.
Mathieu says:
I created a module in LTTng that uses kallsyms to get the symbol
corresponding to a specific system call address. Unfortunately, all the
unimplemented syscalls were all referring to the (same) weak symbol
identifying an unrelated system call rather that sys_ni (or whatever
non-weak symbol would be expected). Kallsyms was dumbly returning the first
symbol that matched.
This patch makes sure kallsyms returns the non-weak symbol when there is
one, which seems to be the expected result.

When passing a zero address to kallsyms_lookup(), the kernel thought it was
a valid kernel address, even if it is not. This is because is_ksym_addr()
called is_kernel_extratext() and checked against labels that don't exist on
many archs (which default as zero). Since PPC was the only kernel which
defines _extra_text, (in 2005), and no longer needs it, this patch removes
_extra_text support.

We have had warnings for a long time about select of unknow symbol
but the warnings does not really makes sense since we may
select a symbol that is relevant and defined in one
arch but not in another arch.
And as long as we do not use a common set of Kconfig files
for all archs lets just ignore this case.
Previously we have used this to find bad uses of
select but we need a more relaible method to do so.

Some crazy devices in the wild have a vendor id of 0x0000. If we try to
add a module alias with this id, we just can't do it due to a check in
the file2alias.c file. Change the test to verify that both the vendor
and product ids are 0x0000 to show a real "blank" module alias.
Note, the module-init-tools package also needs to be changed to properly

If there is a mixture of specifying sections for code in gcc
and assembler then if the assembler code do not add
the "ax" flags the linker will see this as two different sections
and generate unique sections for each. ld does so by adding a dot
and a number.
Teach modpost to warn if a section shows up that match this
pattern - but do this only for non-debug sections.
It will result in warnings like this:
WARNING: vmlinux.o (.sched.text.1): unexpected section name.
The (.[number]+) following section name are ld generated and not expected.
Did you forget to use "ax"/"aw" in a .S file?
Note that for example <linux/init.h> contains
section definitions for use in .S files.
All warnings seen with a defconfig build for:
x86 (32+64bit) and sparc64 has been fixed (via respective maintainers).
arm, powerpc (64 bit), s390 (32 bit), ia64, alpha, sh4 checked - no
warnings seen with a defconfig build.

If the config option CONFIG_SECTION_MISMATCH is not set and
we see a Section mismatch present the following to the user:
modpost: Found 1 section mismatch(es).
To see additional details select "Enable full Section mismatch analysis"
in the Kernel Hacking menu (CONFIG_SECTION_MISMATCH).
If the option CONFIG_SECTION_MISMATCH is selected
then be verbose in the Section mismatch reporting from mdopost.
Sample outputs:
WARNING: o-x86_64/vmlinux.o(.text+0x7396): Section mismatch in reference from the function discover_ebda() to the variable .init.data:ebda_addr
The function discover_ebda() references
the variable __initdata ebda_addr.
This is often because discover_ebda lacks a __initdata
annotation or the annotation of ebda_addr is wrong.
WARNING: o-x86_64/vmlinux.o(.data+0x74d58): Section mismatch in reference from the variable pci_serial_quirks to the function .devexit.text:pci_plx9050_exit()
The variable pci_serial_quirks references
the function __devexit pci_plx9050_exit()
If the reference is valid then annotate the
variable with __exit* (see linux/init.h) or name the variable:
*driver, *_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console,
WARNING: o-x86_64/vmlinux.o(__ksymtab+0x630): Section mismatch in reference from the variable __ksymtab_arch_register_cpu to the function .cpuinit.text:arch_register_cpu()

Change kconfig behavior so that mixing bool and tristate config
settings in a choice is possible and has the desired effect of offering
just the tristate options individually if the choice gets set to M, and
a normal boolean selection if the choice gets set to Y.
Also fix scripts/kconfig/conf's handling of children of choice values -
there may be more than one immediate child, and all of them need to be
processed.

Introducing separate sections for __dev* (HOTPLUG),
__cpu* (HOTPLUG_CPU) and __mem* (MEMORY_HOTPLUG)
allows us to do a much more reliable Section mismatch
check in modpost. We are no longer dependent on the actual
configuration of for example HOTPLUG.
This has the effect that all users see much more
Section mismatch warnings than before because they
were almost all hidden when HOTPLUG was enabled.
The advantage of this is that when building a piece
of code then it is much more likely that the Section
mismatch errors are spotted and the warnings will be
felt less random of nature.

Change the logic in modpost so we identify all the
bad combinations of sections that refer to other
sections.
Compared to the previous approach we are much less
dependent on knowledge of what additional sections
the tool chain uses and thus we can keep the false
positives low.
The implmentation is changed to use a table based
lookup and we now check all combinations in first
pass so we no longer need separate passes for init
and exit sections.
Tested that the same warnings are generated for
an allyesconfig build without CONFIG_HOTPLUG.
