0758416325 bugfix for scripts/patch-kernel in 2.6 sublevel stepping
scripts/patch-kernel script can't patch a tree, say, from 2.6.25 to
2.6.26.1, because of a wrong comparison in context of patching 2.6.x base.

32ab8f97dd kernel-doc: skip nested struct/union cleanly
Fix handling of nested structs or unions.  The regex to strip (eliminate)
nested structs or unions was limited to only 0 or 1 matches.  This can
cause an uneven number of left/right braces to be stripped, which causes
this:

759da92671 firmware: silence __fw_modbuild and __fw_modinst 'Nothing to be done' messages

94aa3d716e kbuild: genksyms parser: fix the __attribute__ rule
We are having two kinds of problems with genksyms today: fake checksum
changes without actual ABI changes, and changes which we would rather like
to ignore (such as an additional field at the end of a structure that
modules are not supposed to touch, for example).

I have thought about ways to improve genksyms and compute checksums
differently to avoid those problems, but in the end I don't see a
fundamentally better way.  So here are some genksyms patches for at least
making the checksums more easily manageable, if we cannot fully fix them.

In addition to the bugfixes (the first two patches), this allows genksyms
to track checksum changes and report why a checksum changed (third patch),
and to selectively ignore changes (fourth patch).

This patch:

Gcc __attribute__ definitions may occur repeatedly, e.g.,

	static int foo __attribute__((__used__))
		       __attribute__((aligned (16)));

The genksyms parser does not understand this, and generates a syntax error.
Fix this case.

09748e178b kconfig: make defconfig is no longer chatty
make defconfig generated a lot of output
then noone actually read.
Use conf_set_all_new_symbols() to generate the default
configuration and avoid the chatty output.

A typical run now looks like this:
$ make  defconfig
*** Default configuration is based on 'i386_defconfig'
arch/x86/configs/i386_defconfig:13:warning: trying to assign nonexistent symbol SEMAPHORE_SLEEPERS
arch/x86/configs/i386_defconfig:176:warning: trying to assign nonexistent symbol PREEMPT_BKL
...
arch/x86/configs/i386_defconfig:1386:warning: trying to assign nonexistent symbol INSTRUMENTATION
$

As an added benefit we now clearly see the warnings generated
in the start of the process.

cd9140e1e7 kconfig: make oldconfig is now less chatty
Previously when running "make oldconfig" we saw all the propmt lines
from kconfig and noone actully read this.

With this patch the user will only see output if there is new symbols.
This will be seen as "make oldconfig" runs which does not generate any output.

A typical run now looks like this:

$ make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
$

If a new symbol is found then we restart the config process like this:
$ make oldconfig
scripts/kconfig/conf -o arch/x86/Kconfig
*
* Restart config...
*
*
* General setup
*
Prompt for development and/or incomplete code/drivers (EXPERIMENTAL) [Y/n/?] y
Local version - append to kernel release (LOCALVERSION) []
...

The bahaviour is similar to what we know when running the implicit
oldconfig target "make silentoldconfig".
"make silentoldconfig" are run as part of the kernel build process
if the configuration has changed.

7712401ae9 kbuild: optimize headers_* targets
Move the core functionality of headers_install
and headers_check to two small perl scripts.
The makefile is adapted to use the perl scrip and
changed to operate on all files in a directory.
So if one file is changed then all files in the
directory is processed.

perl were chosen for the helper scripts because this
is pure text processing which perl is good at and
especially the headers_check.pl script are expected to
see changes / new checks implmented.

The speed is ~300% faster on this box.
And the output generated to the screen is now down to
two lines per directory (one for install, one for check)
so it is easier to scroll back after a kernel build.

The perl scripts has been brought to sanity by patient
feedback from: Vegard Nossum <vegard.nossum@gmail.com>

88181ec30f kbuild: only one call for include/ in make headers_*
Move it to the top-level file to decide if we install/check
the generic headers or the arch specific headers.

This revealed a long standing bug where "make headers_check_all"
relied on the files in asm/ for the current architecture.
So make headers_check_all is now broken by this commit.

In addition:

o add a simpler way to detect if an arch support
  exporting header files.

o add 'set -e;' so we error out early if
  make headers_check_all fails.

o add sparc64 and cris to arch we do not process
  in make headers_*_all because:

    sparc64 - use sparc to export headers
    cris    - is know seriously broken

585e93ae83 find dynamic stack allocations in checkstack.pl
Currently, checkstack.pl only looks for fixed subtractions from the stack
pointer.  However, things like this:

void function(int size)
{
        char stackbuster[size << 2];
...

are certainly worth pointing out, I think.

This could perhaps be done more cleanly, and the following patch only
adds "dynamic" REs for x86 and x86_64, but it works:

0x00b0 crypto_cbc_decrypt_inplace [cbc]:                Dynamic (%rax)
0x00ad crypto_pcbc_decrypt_inplace [pcbc]:              Dynamic (%rax)

f606ddf42f remove the v850 port
Trying to compile the v850 port brings many compile errors, one of them exists
since at least kernel 2.6.19.

There also seems to be noone willing to bring this port back into a usable
state.

This patch therefore removes the v850 port.

If anyone ever decides to revive the v850 port the code will still be
available from older kernels, and it wouldn't be impossible for the port to
reenter the kernel if it would become actively maintained again.

4d7365d664 kbuild: ignore powerpc specific symbols in modpost
Kumar Gala <galak@kernel.crashing.org> wrote:
We have a case in powerpc in which we want to link some library
routines with all module objects.  The routines are intended for
handling out-of-line function call register save/restore so having
them as EXPORT_SYMBOL() is counter productive (we do also need to
link the same "library" code into the kernel).

Without this patch a powerpc build would error out and fail
to build modules with the added register save/restore module.

There were two obvious solutions:
1) To link the .o file before the modpost stage
2) To ignore the symbols in modpost

Option 1) was ruled out because we do not have any separate
linking stage for single file modules.

This patch implements option 2 - and do so only for powerpc.

The symbols we ignore are all undefined symbols named:
_restgpr_*, _savegpr_*, _rest32gpr_*, _save32gpr_*

c45dcabd26 update checkpatch.pl to version 0.19
This version is a bit of a whopper.  This version brings a few new checks,
improvements to a number of checks mostly through modifications to the
way types are parsed, several fixes to quote/comment handling, as well as
the usual slew of fixes for false positives.

Of note:
 - return is not a function and is now reported,
 - preprocessor directive detection is loosened to match C99 standard,
 - we now intuit new type modifiers, and
 - comment handling is much improved

Andy Whitcroft (18):
      Version: 0.19
      fix up a couple of missing newlines in reports
      colon to parenthesis spacing varies on asm
      values: #include is a preprocessor statement
      quotes: fix single character quotes at line end

      kerneldoc parameters must be on one line, relax line length
      types: word boundary is not always required
      improved #define bracketing reports
      uninitialized_var is an annotation not a function name
      possible types: add possible modifier handling
      possible types: fastcall is a type modifier
      types: unsigned is not a modifier on all types
      static/external initialisation to zero should allow modifiers
      checkpatch: fix recognition of preprocessor directives -- part 2
      comments: fix inter-hunk comment tracking
      return is not a function

96d97f262a kbuild: fix $(src) assignmnet with external modules
When we introduced support for KBUILD_EXTRA_SYMBOLS
we started to include the externam module's kbuild
file when doing the final modpost step.

As external modules often do:
ccflags-y := -I$(src)

We had problems because $(src) was unassinged and
gcc then used the next parameter for -I resulting in
strange build failures.

Fix is to assign $(src) and $(obj) when building
external modules.

656ee82cc8 kbuild: create new CFLAGS_REMOVE_(basename).o option
We currently have a way to add special CFLAGS to code, but we do not have a
way to remove them if needed.

With the case of ftrace, some files should simply not be profiled. Adding
the -pg flag to these files is simply a waste, and adding "notrace" to each
and every function is ugly.

Currently we put in "Makefile turd" [1] to stop the compiler from adding -pg
to certain files. This was clumsy and awkward.

This patch now adds the revese of CFLAGS_(basename).o with
CFLAGS_REMOVE_(basename).o.  This allows developers to prevent certain
CFLAGS from being used to compile files. For example, we can now do

CFLAGS_REMOVE_string.o = -pg

to remove the -pg option from the string.o file in the lib directory.

Note: a space delimited list of options may be added to the REMOVE macro.

[1] - what David Miller called the workaronud to remove -pg

fd1db0a313 kbuild: disable modpost warnings for linkonce sections
Disable modpost warnings for linkonce sections

My build gives lots of warnings like

WARNING: sound/core/snd.o (.gnu.linkonce.wi.mpspec_def.h.30779716): 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.

But for .linkonce. duplicated sections are actually ok and expected.
So just disable the warning for this case.

ac55182899 modpost: i2c aliases need no trailing wildcard
Not all device types need a wildcard at the end of their module
aliases. In particular, for i2c module aliases, the trailing wildcard
is not only unneeded, it could also cause the wrong driver to be
loaded.

As I2C devices have no IDs, i2c module aliases are simple, arbitrary
device names. For example:

$ /sbin/modinfo lm90
filename:       /lib/modules/2.6.25-git18/kernel/drivers/hwmon/lm90.ko
author:         Jean Delvare <khali@linux-fr.org>
description:    LM90/ADM1032 driver
license:        GPL
vermagic:       2.6.25-git18 mod_unload
depends:        hwmon
alias:          i2c:lm90*
alias:          i2c:adm1032*
alias:          i2c:lm99*
alias:          i2c:lm86*
alias:          i2c:max6657*
alias:          i2c:adt7461*
alias:          i2c:max6680*
$

This would cause trouble if one I2C chip name matches the beginning of
another I2C chip name and both chips are supported by different
drivers. For example, an i2c device named lm9042 would cause the lm90
driver to be loaded, while it doesn't support that device. This case
has yet to be seen in practice, but still, I'd like to fix it now. The
cleanest fix is to remove the trailing wildcard from i2c module aliases.

Here's a patch doing this.

Not all device type aliases need a trailing wildcard, in particular
the i2c aliases don't. Don't add a wildcard by default in do_table(),
instead let each device type handler add it if needed.

I have tested types acpi, dmi, eisa, i2c, ide, ieee1394, input, pci,
pcmcia, platform, pnp, scsi, serio, ssb and usb. Other types (ccw, of,
vio, parisc, sdio and virtio) are untested.

d2653e9273 i2c: Add support for device alias names
Based on earlier work by Jon Smirl and Jochen Friedrich.

This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.

9c9ba34ee3 update checkpatch.pl to version 0.18
This version brings a few fixes for the extern checks, and a couple of
new checks.

Of note:
 - false is now recognised as a 0 assignment in static/external
   assignments,
 - printf format strings including %L are reported,
 - a number of fixes for the extern in .c file detector which had
   temporarily lost its ability to detect variables; undetected due to
   the loss of its test.

Andy Whitcroft (8):
      Version: 0.18
      false should trip 0 assignment checks
      tests: reinstate missing tests
      tests: allow specification of the file extension for a test
      fix extern checks for variables
      check for and report %Lu, %Ld, and %Li
      ensure we only start a statement on lines with some content
      extern spacing

171ae1a491 update checkpatch.pl to version 0.17
This version brings improvements to external declaration detection, fixes to
quote tracking, fixes to unary tracking, some clarification of wording, and
the usual slew of fixes for false positives.

Of note:
 - much better unary tracking across preprocessor directives
 - UTF8 checks highlight the character at fault
 - widening of mutex detection

Andy Whitcroft (17):
      Version: 0.17
      values: __attribute__ carries through the previous type
      quotes: should only follow "positive" lines
      clarify the indent tabs over spaces wording
      loosen NR_CPUS check for array range initialisers
      detect external function declarations without an extern prefix
      function declaration arguments should be with the identifier
      DEFINE_MUTEX should report in line with struct mutex
      NR_CPUS is valid in preprocessor statements
      comment detection should not start on the @@ line
      types: add support for #undef
      tighten mutex/completion reports to usage
      allow export of function pointers
      values: preprocessor #define is out of line maintain values
      values: #define does not always have parentheses
      unary '*' may be const
      utf8 checks should report location of the invalid character

5a1aa8a1af kconfig: add named choice group
As choice dependency are now fully checked, it's quite easy to add support
for named choices. This lifts the restriction that a choice value can only
appear once, although it still has to be within the same group,
but multiple choices can be joined by giving them a name.
While at it I cleaned up a little the choice type logic to simplify it a
bit.

94dc7ad550 kernel-doc: detect/prevent duplicate doc section names
I saw this problem recently.  With this kernel-doc:

 * Note: some important info
 *
 * Note: other important info

kernel-doc uses the "section name" (preceding the ':', like "Note") as a hash
key for storing the descriptive text ("blah important info").  It is (was)
possible to have duplicate (colliding) section names, without any kind of
warning or error.

kernel-doc happily used the latter descriptive text for all instances of
printing the <section-name> descriptive text and the former important info
was lost.

One way to "fix" this is to modify the kernel-doc comments, e.g.:

 * Note1: foo bar
 *
 * Note.2: blah zay

For now, kernel-doc will signal an error when it sees colliding section names
like this.
