[PATCH kbuild-next] kconfig/lxdialog: Add definitions for mininimum (re)size values

Sedat Dilek — 2013-06-15T09:07:35

Commit c8dc68ad0fbd ("kconfig/lxdialog: support resize") added support
for resizing, but forgot to collect all hardcoded values at one single
place.

Also add a definition for the check for a minimum screen/window size
of 80x19.

[ ChangeLog v3:
  * Rename MENU_{HEIGTH,WIDTH}_MIN -> MENUBOX_{HEIGTH,WIDTH}_MIN
  ChangeLog v2:
  * Rename WIN_{HEIGTH,WIDTH}_MIN -> WINDOW_{HEIGTH,WIDTH}_MIN
  * Mention the check for a minimum screen/window size in the changelog
  * Add a comment above the block of new definitions ]

[PATCH v5 0/4] deb-pkg: bring it a little closer to debian packaging

Anisse Astier — 2013-06-14T09:46:53

These little fixes should bring debian packaging closer to the way it's done in debian.

Changes in:
v2:
 - only build debug packages when CONFIG_DEBUG_INFO=y
 - build debug package last.
 - more verbose debug package description
 - put package in section debug
v3:
 - remove duplicate code from v2
v4:
 - fixes thanks to Ben Hutchings' review
 - use KCONFIG_CONFIG instead of .config
 - use installed path specific to each architecture instead of hard-coded
   /boot/vmlinuz-$version, based on
   http://anonscm.debian.org/viewvc/kernel/dists/wheezy/linux/debian/rules.real?view=markup
v5:
 - fixes thanks to Ben Hutchings' review
 - don't use $objtree as it's redundant in build scripts
 - add symbolic links to vmlinux to work with other tools than perf
 - pick-up reviewed-by from ml for patch 3 and 4


Anisse Astier (4):
  deb-pkg: use KCONFIG_CONFIG instead of .config file directly
  deb-pkg: split debug symbols in their own package
  deb-pkg: fix installed image path on parisc, mips and powerpc
  deb-pkg: add a

[PATCH RESEND] Makefile.lib: align DTB quiet_cmd

James Hogan — 2013-06-13T10:53:09

The unaligned dtb.S filename in make output started to irritate me:
  DTC     arch/metag/boot/dts/skeleton.dtb
  DTB    arch/metag/boot/dts/skeleton.dtb.S
  AS      arch/metag/boot/dts/skeleton.dtb.o
  LD      arch/metag/boot/dts/built-in.o

Add an extra space to quiet_cmd_dt_S_dtb so the dtb.S filename aligns
with all the others.

[PATCH REPOST] dtc: ensure #line directives don't consume data from the next line

Stephen Warren — 2013-06-12T16:18:44

From: Stephen Warren <swarren< at >nvidia.com>

Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS}
could match line-break characters. If the #line directive did not contain
the optional flags field at the end, this could cause any integer data on
the next line to be consumed as part of the #line directive parsing. This
could cause syntax errors (i.e. #line parsing consuming the leading 0
from a hex literal 0x1234, leaving x1234 to be parsed as cell data,
which is a syntax error), or invalid compilation results (i.e. simply
consuming literal 1234 as part of the #line processing, thus removing it
from the cell data).

Fix this by replacing {WS} with [ \t] so that it can't match line-breaks.

Convert all instances of {WS}, even though the other instances should be
irrelevant for any well-formed #line directive. This is done for
consistency and ultimate safety.

This is a port of upstream dtc commit a1ee6f0 (with same subject) to the
kernel's copy of dtc.

[PATCH 1/2] Fix a build warning in scripts/sortextable.h

Daniel Tang — 2013-06-09T02:33:54

The pointer passed to the _r() macro does not always match the type
of the function that it is aliasing and raises several of the following
warnings at compile time:

warning: passing argument 1 of ‘r8’ from incompatible pointer type

Fixed by casting the pointers to (void *) so they work with both the
32bit and 64bit code.

[PATCH v6] kbuild: fix error when building from src rpm

Mike Marciniszyn — 2013-06-07T16:25:33

The following issue can be reproduced with Linus' tree on
and x86_64 server.


Here are the commands to reproduce:

make defconfig
make rpm-pkg

Use the resulting src rpm to build as follows:

mkdir ~/rpmbuild-test
cd ~/rpmbuild-test
rpmbuild --rebuild --define "_topdir `pwd`" -vv ~/rpmbuild/SRPMS/kernel-3.10.0_rc1+-1.src.rpm

The issue is because the %install script uses $KBUILD_IMAGE and it hasn't
been set since it is only available in the kbuild system and not in the
%install script.

This patch adds a Makefile target to emit the image_name that can be used
and modifies the mkspec to use the dynamic name in %install.

Sorry for the confusion with the patch.

I haven't tested SLES11SP2 yet.

[PATCH] let kbuild mkdir for dir/file.o

张忠山 — 2013-06-04T08:45:31

Last week I send this patch, but no reply.
Now I try to explain it clearly:

When I try to add a file(which in a subdir) to my board's obj-y, the build progress crashed.

for example, I use at91rm9200ek board, and in kernel dir run:

mkdir objtree
make O=objtree at91rm9200-defconfig
mkdir arch/arm/mach-at91/dir
touch arch/arm/mach-at91/dir/file.c

and edit arch/arm/mach-at91/dir/file.c to add some code.
then edit arch/arm/mach-at91/Makefile, change the flowwing line:

obj-$(CONFIG_MACH_AT91RM9200EK)+= board-rm9200ek.o

to:

obj-$(CONFIG_MACH_AT91RM9200EK)+= board-rm9200ek.o dir/file.o

Now build it:

make O=objtree

Then the error appears:
...
CC      arch/arm/mach-at91/board-rm9200dk.o
CC      arch/arm/mach-at91/board-rm9200ek.o
CC      arch/arm/mach-at91/dir/file.o
linux-2.6/arch/arm/mach-at91/dir/file.c:5: fatal error: opening dependency file arch/arm/mach-at91/dir/.file.o.d: No such file or directory

Check the objtree:
LANG=en ls objtree/arch/arm/mach-at91/dir
ls: cannot access objtree/a

[PATCH] dtc: ensure #line directives don't consume data from the next line

Stephen Warren — 2013-06-03T15:36:56

From: Stephen Warren <swarren< at >nvidia.com>

Previously, the #line parsing regex ended with ({WS}+[0-9]+)?. The {WS}
could match line-break characters. If the #line directive did not contain
the optional flags field at the end, this could cause any integer data on
the next line to be consumed as part of the #line directive parsing. This
could cause syntax errors (i.e. #line parsing consuming the leading 0
from a hex literal 0x1234, leaving x1234 to be parsed as cell data,
which is a syntax error), or invalid compilation results (i.e. simply
consuming literal 1234 as part of the #line processing, thus removing it
from the cell data).

Fix this by replacing {WS} with [ \t] so that it can't match line-breaks.

Convert all instances of {WS}, even though the other instances should be
irrelevant for any well-formed #line directive. This is done for
consistency and ultimate safety.

This is a port of upstream dtc commit a1ee6f0 (with same subject) to the
kernel's copy of dtc.
