2013-07-03checkpatch: ignore existing CamelCase uses from include/...Joe Perches
When using --strict, CamelCase uses are described with CHECK: messages. These CamelCase uses may be acceptable and should not generate these messages when the variable is already defined in a file from the include/... path. So, change checkpatch to read all the .h files in include/... and look for preexisting CamelCase #defines, typedefs and function prototypes. Add these to the existing camelcase hash so that any uses in the patch or file can be ignored. There are currently ~3500 files in include/. It takes about 10 cpu seconds on my little netbook to grep for and preseed these existing uses. That's about 4x the time for a similar git grep. This preseeding is only done once when using --strict and only when there is a CamelCase use found. If a .git directory is found, it uses 'git ls-files include' If not, it uses 'find $root/include -name "*.h" Signed-off-by: Joe Perches <joe@perches.com> Cc: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

When 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 following 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: ...

2013-06-24scripts/setlocalversion on write-protected source treeChristian Kujau
I just stumbled across another[0] issue when scripts/setlocalversion operates on a write-protected source tree. Back then[0] the source tree was on an read-only NFS share, so "test -w" was introduced before "git update-index" was run. This time, the source tree is on read/write NFS share, but the permissions are world-readable and only a specific user (or root) can write. Thus, "test -w ." returns "0" and then runs "git update-index", producing the following message (on a dirty tree): fatal: Unable to create '/usr/local/src/linux-git/.git/index.lock': Permission denied While it says "fatal", compilation continues just fine. However, I don't think a kernel compilation should alter the source tree (or the .git directory) in any way and I don't see how removing "git update-index" could do any harm. The Mercurial and SVN routines in scripts/setlocalversion don't have any tree-modifying commands, AFAICS. So, maybe the patch below would be acceptable.

2013-06-13dtc: ensure #line directives don't consume data from the next lineGrant Likely
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.

2013-06-12arm64: extable: sort the exception table at build timeWill Deacon
As is done for other architectures, sort the exception table at build-time rather than during boot. Since sortextable appears to be a standalone C program relying on the host elf.h to provide EM_AARCH64, I've had to add a conditional check in order to allow cross-compilation on machines that aren't running a bleeding-edge libc-dev.

2013-05-30kconfig/menu.c: fix multiple references to expressions in menu_add_prop()Dirk Gouders
menu_add_prop() applies upper menus' visibilities to actual prompts by AND-ing the prompts visibilities with the upper menus ones. This creates a further reference to the menu's visibilities and when the expression reduction functions do their work, they may remove or modify expressions that have multiple references, thus causing unpredictable side-effects. The following example Kconfig constructs a case where this causes problems: a menu and a prompt which's visibilities depend on the same symbol. When invoking mconf with this Kconfig and pressing "Z" we see a problem caused by a free'd expression still referenced by the menu's visibility: ------------------------------------------------------------------------ mainmenu "Kconfig Testing Configuration" config VISIBLE def_bool n config Placeholder bool "Place holder" menu "Invisible" visible if VISIBLE config TEST_VAR bool "Test option" if VISIBLE endmenu ------------------------------------------------------------------------ This patch fixes this problem by creating copies of the menu's visibility expressions before AND-ing them with the prompt's one.

2013-05-30mconf: handle keys in empty dialogsDirk Gouders
When entering an empty dialog, using the movement keys resulted in unexpected characters beeing displayed, other keys like "z" and "h" did not work as expected. This patch handles the movement keys as well as other keys, especially "z", "h" and "/".

2013-05-23kbuild: Don't assume dts files live in arch/*/boot/dtsMatthijs Kooijman
In commit b40b25ff (kbuild: always run gcc -E on *.dts, remove cmd_dtc_cpp), dts building was changed to always use the C preprocessor. This meant that the .dts file passed to dtc is not the original, but the preprocessed one. When compiling with a separate build directory (i.e., with O=), this preprocessed file will not live in the same directory as the original. When the .dts file includes .dtsi files, dtc will look for them in the build directory, not in the source directory and compilation will fail. The commit referenced above tried to fix this by passing arch/*/boot/dts as an include path to dtc. However, for mips, the .dts files are not in this directory, so dts compilation on mips breaks for some targets. Instead of hardcoding this particular include path, this commit just uses the directory of the .dts file that is being compiled, which effectively restores the previous behaviour wrt includes. For most .dts files, this path is just the same as the previous hardcoded arch/*/boot/dts path. This was tested on a mips (rt3052) and an arm (bcm2835) target.

2013-05-20scripts/config: fix assignment of parameters for short version of --*-after ↵Clement Chauplannaz
options When --*-after options are used, two parameters are parsed from the command-line before the adequate function is called: - the `before' option, after which the new option will be inserted, - the name of the option to enable/disable/modularise. With the short version of --*-after options (namely -E, -D, -M), the parsing step is not performed which leads to processing unset variables. Add options -E, -D, -M to the test that triggers assignment of parameters for --*-after options.

2013-05-17kbuild: fix make headers_install when path is too longNicolas Dichtel
If headers_install is executed from a deep/long directory structure, the shell's maximum argument length can be execeeded, which breaks the operation with: | make[2]: execvp: /bin/sh: Argument list too long | make[2]: *** Instead of passing each files name with the entire path, I give only the file name without the source path and give this path as a new argument to headers_install.pl. Because there is three possible paths, I have tree input-files list, one per path.
