With this patch when ncurses-devel (or whatever it is named)
is missing trying to run menuconfig will result in this:
$ make menuconfig
HOSTCC scripts/kconfig/conf.o
HOSTCC scripts/kconfig/kxgettext.o
*** Unable to find the ncurses libraries or the
*** required header files.
*** 'make menuconfig' requires the ncurses libraries.
***
*** Install ncurses (ncurses-devel) and try again.
***
make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
make: *** [menuconfig] Error 2
Much better than before where we just listed some build errors.
The other *config targets will work indepenednt on ncurses
being present or not.

When multiple built-in modules (especially drivers) provide the same
capability, they're prioritized by link order specified by the order
listed in Makefile. This implicit ordering is lost for loadable
modules.
When driver modules are loaded by udev, what comes first in
modules.alias file is selected. However, the order in this file is
indeterministic (depends on filesystem listing order of installed
modules). This causes confusion.
The solution is two-parted. This patch updates kbuild such that it
generates and installs modules.order which contains the name of
modules ordered according to Makefile. The second part is update to
depmod such that it generates output files according to this file.
Note that both obj-y and obj-m subdirs can contain modules and
ordering information between those two are lost from beginning.
Currently obj-y subdirs are put before obj-m subdirs.
Sam Ravnborg cleaned up Makefile modifications and suggested using awk
to remove duplicate lines from modules.order instead of using separate
C program.

bloat-o-meter assumes that a '.' anywhere in a symbol's name means that it
is static and prepends 'static.' to the first part of the symbol name,
discarding the portion of the name that follows the '.'. However, the
names of function entry points begin with '.' in the ppc64 ABI. This
causes all function text size changes to be accounted to a single 'static.'
entry in the output when comparing ppc64 kernels.
Change getsizes() to ignore the first character of the symbol name when
searching for '.'.

This version brings a new terse output mode as well as many improvements to
the unary detection and bare type regcognition. It also brings the usual
updates for false positives, though these seem to be slowing markedly
now that the unary detector is no longer just putting its finger in the
air and guessing. Of note:
- new --terse mode producing a single line per report
- loosening of the block brace checks
- new checks for enum/union/struch brace placements
- hugely expanded "bare type" detection
- checks for inline usage
- better handling of already open comment blocks
- handle patches which introduce or remove lines without newlines
Andy Whitcroft (19):
Version: 0.12
style fixes as spotted by checkpatch
add a --terse options of a single line of output per report
block brace checks should only apply for single line blocks
all new bare type detector

Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
all.config.
For a fix the diffstat is nice:
6 files changed, 3 insertions(+), 36 deletions(-)
The patch reverts these commits:
- 0f855aa64b3f63d35a891510cf7db932a435c116 ("kconfig: add helper to set
config symbol from environment variable")
- 2a113281f5cd2febbab21a93c8943f8d3eece4d3 ("kconfig: use $K64BIT to
set 64BIT with all*config targets")
Roman Zippel pointed out that kconfig supported string compares so
the additional complexity introduced by the above two patches were
not needed.
With this patch we have following behaviour:
# make {allno,allyes,allmod,rand}config [ARCH=...]
option \ host arch | 32bit | 64bit
=====================================================
./. | 32bit | 64bit
ARCH=x86 | 32bit | 32bit
ARCH=i386 | 32bit | 32bit
ARCH=x86_64 | 64bit | 64bit
The general rule are that ARCH= and native architecture takes
precedence over the configuration.
So make ARCH=i386 [whatever] will always build a 32-bit kernel
no matter what the configuration says. The configuration will
be updated to 32-bit if it was configured to 64-bit and the
other way around.
This behaviour is consistent with previous behaviour so no
suprises here.
make ARCH=x86 will per default result in a 32-bit kernel but as
the only ARCH= value x86 allow the user to select between 32-bit
and 64-bit using menuconfig.

After unification of the Kconfig files and
introducing K64BIT support in kconfig
it required only trivial changes to enable
"make ARCH=x86".
With this patch you can build for x86_64 in several ways:
1) make ARCH=x86_64
2) make ARCH=x86 K64BIT=y
3) make ARCH=x86 menuconfig
=> select 64-bit
Likewise for i386 with the addition that
i386 is default is you say ARCH=x86.

The variable K64BIT can now be used to select the
value of CONFIG_64BIT.
This is for example useful for powerpc to generate
allmodconfig for both bit sizes - like this:
make ARCH=powerpc K64BIT=y
make ARCH=powerpc K64BIT=n
To use this the Kconfig file must use "64BIT" as the
config value to select between 32 and 64 bit.

This reverts commit a5bf3d891a6a0fb5aa122792d965e3774108b923.
David Brownell notes that this causes a regression visible in the
drivers/usb/gadget Kconfig file:
"That Kconfig hasn't changed (other than adding new drivers), and it's
worked that way for several years now ... so the issue seems to be
changes in menuconfig/kconfig/etc semantics.
The issue is that when USB_GADGET=m, it's no longer possible to
configure peripheral controller drivers as modules ... the
controller drivers can now only be configured for static linkage.
It should be making a choice of one of the controller drivers which
could work on the target system, and allow that driver to be linked
either as a module (ok iff USB_GADGET=m) or statically."
Reverting this commit resolves the problem, and also fixes a second
problem that David noticed: various dependent options couldn't be enabled.

cc-cross-prefix is useful for the architecture that like
to provide a default CROSS_COMPILE value,
but may have several to select between.
Sample usage:
ifneq ($(SUBARCH),$(ARCH))
ifeq ($(CROSS_COMPILE),)
CROSS_COMPILE := $(call cc-cross-prefix, m68k-linux-gnu- m68k-linux-)
endif
endif
Actual usage by the different archs will taken care of later.

This version brings a more cautious checkpatch.pl by default. The more
subjective checks are only applied with the --strict option. It also
brings the usual slew of corrections for false positives. Of note:
- new tree detection, the source tree will be found via the executable
- a major revamp of the unary detection to make it more parser like
- a new summary at the bottom of the report
- --strict option for subjective checks
- --file to enable checking on complete files
- support for use in emacs "compile" window

add new --file mode to handle raw source files
add --strict/--subjective which enables the subjective tests

When part of build an external module tree, modpost first reads in the
kernel's and then the external tree's Module.symvers files. From these files
it establishes a symbol => module mapping. When it later reads in each module
built and processes the symbols it finds, it discovers the symbol=>module
mapping from Module.symvers and leaves it as it is.
The problem comes with a module has been re-named or a symbol has moved from
one module to another, since the Module.symvers file was generated. modpost
does not update the symbol=>module mapping when it finds the new location of
the symbol when scanning the newly built modules. This results in the module
containing incorrect dependency information and the new Module.symvers file
written by modpost will also contain the incorrect mappings, perpetuating the
problem to the next build, and so on.
When building the out of kernel development tree for kernel subsystem, like
v4l-dvb or ALSA, deleting the external Module.symvers file before building
(which the kernel build system doesn't do and shouldn't be necessary anyway),
won't fix the problem. modpost still reads the kernel's Module.symvers, and
since we a building a kernel subsystem, it will define the same symbols as the
external modules.

Johannes Berg reports (Thanks!) that &struct names are not highlighted in
html output format when they are inside a DOC: block.
DOC: blocks were not escaped thru xml_escape() like other kernel-doc
comments were. Fixed that.
However, that left a problem with <p> ($blankline_html) being processed
thru xml_escape(), converting it to <p>, which isn't good for the
generated html output (the <p> should remain unchanged), so this patch also
introduces the notion of "local" kernel-doc meta-characters
('\\\\mnemonic:'), which are converted to html just before writing the
stream to its output file.
Please report any problems that you (anyone) see in "highlighting" in any

Introduce ccflags-y, asflags-y and ldflags-y so we soon can
deprecate use of EXTRA_CFLAGS, EXTRA_AFLAGS and EXTRA_LDFLAGS.
This patch does not touch any in-tree users - thats next round.
Lets get this committed first and then fix the users of the
soon to be deprecated variants next.
The rationale behind this change is to introduce support for
makefile fragments like:
ccflags-$(CONFIG_WHATEVER_DEBUG) := -DDEBUG
As a replacement for the uglier:
ifeq ($(CONFIG_WHATEVER_DEBUG),y)
EXTRA_CFLAGS := -DDEBUG

External modules have in a few cases modifed gcc option
by modifying CFLAGS. This has never been documented and
was a bad practice.
With the check to use KBUILD_CFLAGS it will no longer work
so we better error out and tell what was wrong as a service
to the external module users.
This check can be overruled if
KBUILD_NOPEDANTIC is set to something.
Addid this possibility may allow older external
module to build without any code modifications but potentially
only loosing some un-important gcc options.

The variable CFLAGS is a wellknown variable and the usage by
kbuild may result in unexpected behaviour.
On top of that several people over time has asked for a way to
pass in additional flags to gcc.
This patch replace use of CFLAGS with KBUILD_CFLAGS all over the
tree and enabling one to use:
make CFLAGS=...
to specify additional gcc commandline options.
One usecase is when trying to find gcc bugs but other
use cases has been requested too.
Patch was tested on following architectures:
alpha, arm, i386, x86_64, mips, sparc, sparc64, ia64, m68k
Test was simple to do a defconfig build, apply the patch and check
that nothing got rebuild.

I2C devices do not have any form of ID as PCI or USB devices have.
No driver uses "MODULE_DEVICE_TABLE(i2c, ...)" because it doesn't
make sense. So we can get rid of struct i2c_device_id and the
associated support code.

Cause modpost to fail if any device id lists are incorrectly terminated,
after reporting the offender.

menuconfig currently represents options implied by another option ('select'
directive in Kconfig) by prefixing them with '---'. Unfortunately the same
notation is used for comments. If the implied option is module capable,
user can still switch between Y and M, all without any feedback until she
visits option's help. (try saying M to MAC80211 and then toggling
CFG80211)
This patch changes notation of selected-by-another items by introducing 2
new representations for implied options: {*} or {M} for options selected by
another modularized one, thus builtin or module capable, -*- or -M- for
options that cannot be at the moment changed by user.
The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.

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.

These checks has been present for several kernel releases (> 5).
So lets just get rid of them.
With this we no longer check for use of:
EXTRA_TARGETS, O_TARGET, L_TARGET, list-multi, export-objs
There were three remaining in-tree users of O_TARGET in some
unmaintained sh64 code - mail sent to the maintainer + list.

EXTRA_ARFLAGS have never been used so no need to carry
around on this.
A google search did not reveal any external module
using this either.

Change the invocations of make in the output directory Makefile and the
main Makefile for separate object trees to pass all goals to one $(MAKE)
via a new phony target "sub-make" and the existing target _all.
When compiling with separate object directories, a separate make is called
in the context of another directory (from the output directory the main
Makefile is called, the Makefile is then restarted with current directory
set to the object tree). Before this patch, when multiple make command
goals are specified, each target results in a separate make invocation.
With make -j, these invocations may run in parallel, resulting in multiple
commands running in the same directory clobbering each others results.
I did not try to address make -j for mixed dot-config and no-dot-config
targets. Because the order does matter, a solution was not obvious.
Perhaps a simple check for MAKEFLAGS having -j and refusing to run would
be appropriate.
