Jan Engelhardt d84876f9f8 kconfig: allow overriding symbols
Allow config variables in .config to override earlier ones in the same
file. In other words,

	# CONFIG_SECURITY is not defined
	CONFIG_SECURITY=y

will activate it. This makes it a bit easier to do

cat original-config myconfig myconfig2 ... >.config;
and run *config as expected.

Ladislav Michl 09af091f50 kconfig: make kconfig MinGW friendly
Kconfig is powerfull tool. So powerfull that more and more software
projects are using it for configuration. So instead of fixing some of
them one by one, lets fix it in kernel and wait for sync.

This work was originaly done for PTXdist - GPL licensed build system for
userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.

* Do not include <sys/wait.h> and <signal.h> (comes from times when
  lxdialog was separate process)
* Do not mess with termios directly and let curses tell screen size.
  Comment to commit c8dc68ad0f says
  check for screen size could be removed later, but because it didn't
  happen for more than year I left it here as well.
* Save cursor position added by Sam

Theodore Ts'o b052ce4c84 kbuild: fix false positive -dirty tag caused by make-kpkg
make-kpkg modifies scripts/package/Makefile and deletes
scripts/package/builddeb as part of its build process.  Ignore these
changes so the tree isn't marked as -dirty, when it is just an
artifact of make-kpkg.  (make-kpkg clean restores the files to their
original state, and these helper scripts won't affect the final
compiled kernel in any way.)

where 'nnnnn' is the number of commits since the last tag (i.e.,

Andreas Mohr 22d6a6a018 kbuild: eradicate bashisms in scripts/patch-kernel
Make the patch-kernel shell script sufficiently compatible with POSIX
shells, i.e., remove bashisms from scripts/patch-kernel.
This means that it now also works on dash 0.5.3-5
and still works on bash 3.1dfsg-8.

Full changelog:
- replaced non-standard "==" by standard "="
- replaced non-standard "source" statement by POSIX "dot" command
- use leading ./ on mktemp filename to force the tempfile to a local
  directory, so that the search path is not used
- replace bash syntax to remove leading dot by similar POSIX syntax
- added missing (optional/not required) $ signs to shell variable names

Sam Ravnborg 9b213118fa kbuild: fix installing external modules
Eric Sandeen <sandeen@redhat.com> reported:
  Installing external modules is supposed to put them in some path
  under /lib/modules/<version>/extra/subdir/, but this change:
  http://linux.bkbits.net:8080/linux-2.6/?PAGE=cset&REV=1.1982.9.23
  makes them go under /lib/modules/<version>/extrasubdir

 (for example, make M=fs/ext3 modules_install puts ext3.ko in
 /lib/modules/<version>/extrafs/ext3.ko)

This was the case only when specifying a trailing slash to M=..

Fixed by removing trailing slash if present so
we correctly match dir part of target.

Andres Salomon 2f4b489b77 kconfig: use getopt() in conf.c for handling command line arguments
Switch from doing our own parsing of command line arguments to
using getopt(3) to do it.  Aside from simplifying things, this allows us to
specify multiple arguments; the old code could only accept two arguments
(input_mode and kconfig name).

Note some subtle changes:
 - The argument '-?' is no longer supported.
 - '-h' is not treated as an error, so output goes to stdout, and we
   exit with '0'.
 - There is no compatibility checking amongst arguments; the last option
   will simply override earlier options.  For example, 'conf -n -y foo'
   is perfectly valid now (input_mode will be set_yes).  Previously, that
   would have been an error ("can't find file -y").

Tejun Heo 551559e13a kbuild: implement modules.order
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.

discarding the portion of the name that follows the '.'.  However, the

causes all function text size changes to be accounted to a single 'static.'
entry in the output when comparing ppc64 kernels.

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

  - 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

Sam Ravnborg 6840999b19 x86: simplify "make ARCH=x86" and fix kconfig all.config
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:
 - 0f855aa64b ("kconfig: add helper to set
   config symbol from environment variable")
 - 2a113281f5 ("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

it required only trivial changes to enable

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.

Sam Ravnborg 2266cfd50d x86: move defconfig files for i386 and x86_64 to x86
With some small changes to kconfig makefile we can now
locate the defconfig files for i386 and x86_64 in
the configs/ subdirectory under x86.
make ARCH=i386 defconfig and make defconfig
works as expected also after this change.
But arch maintainers shall now update a defconfig file in
the configs/ directory.

Rusty Russell b01d9f2863 Module autoprobing support for virtio drivers.
This adds the logic to convert the virtio ids into module aliases, and
includes a modalias entry in sysfs and the env var to make probing work.

Linus Torvalds e8b8c97773 Revert "kconfig: tristate choices with mixed tristate and boolean values"
This reverts commit a5bf3d891a.

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.

Sam Ravnborg 910b40468a kbuild: introduce cc-cross-prefix
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.

Andy Whitcroft 6c72ffaab9 update checkpatch.pl to version 0.11
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

Andy Whitcroft (27):
      Version: 0.11
      fix up cat_vet for the case where there are no control characters
      any cast to a pointer introduces a type
      cpp unary operator detection needs to float
      attributes are also valid in type definitions
      sizeof may be a bareword and makes its argument unary
      unary checks for #ifdef et al need to find end of line
      add new --file mode to handle raw source files
      add --strict/--subjective which enables the subjective tests
      add some additional standard type suffixes
      cpp #elif is also a unary prefix
      case is not a function name
      widen asm volatile exceptions
      __kprobes is a type attribute
      typeof is a unary operator
      function open parenthesis checks should check all occurances
      expand sizeof() binary exceptions
      linux/irq.h should not be recommended
      work harder to find the kernel root and add --root=
      fix --emacs mode line numbers and string concatenation warnings
      add a summary to the bottom of the main report
      loosen assignment in if checks
      update operator spacing to maintain tabs in output
      revamp unary detection
      corruption/line wrapped patches need only reporting once
      revamp s/u/be/le 8/16/32/64 bit types
      handle missing ,1 in uni-diff header

      Adds support to checkpatch.pl for running in the emacs compile window.

bugme-daemon@bugzilla.kernel.org 6f67a00498 kbuild: make deb-pkg - add 'Provides:' line
http://bugzilla.kernel.org/show_bug.cgi?id=8941

Current Debian's kernel-modules depend on matching linux-image-$version, though
Linux's make deb-pkg build a .deb that 'Provides: kernel-image-$version' only.
The following patch adds the Debian-compliant 'Provides', leaving the default
one; hopely this will make way all happy.
