2013-02-28get_maintainer: allow keywords to match filenamesStephen Warren1-0/+4
Allow K: entries in MAINTAINERS to match directly against filenames; either those extracted from patch +++ or --- lines, or those specified on the command-line using the -f option. This potentially allows fewer lines in a MAINTAINERS entry, if all the relevant files are scattered throughout the whole kernel tree, yet contain some common keyword. An example would be using an ARM SoC name as the keyword to catch all related drivers. I don't think setting exact_pattern_match_hash would be appropriate here; at least for intended Tegra use case, this feature is to ensure that all Tegra-related driver changes get Cc'd to the Tegra mailing list. Setting exact_pattern_match_hash would prevent git history parsing for e.g. S-o-b tags, which still seems like it would be useful. Hence, this flag isn't set.

2013-02-28scripts/kernel-doc: handle struct member __aligned without numbersNishanth Menon1-1/+1
Commit ef5da59f1260 ("scripts/kernel-doc: handle struct member __aligned") permits "char something [123] __aligned(8);". However, by using \d we constraint ourselves with integers. This is not always the case. In fact, it might be better to do char something[123] __aligned(sizeof(u16)); For example, With wireless_dev defining: u8 address[ETH_ALEN] __aligned(sizeof(u16)); With \d, scripts/kernel-doc erroneously says: Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev' This is because the regex __aligned\s*\(\d+\) fails match at \d as sizeof is used. So replace \d with . to indicate "something" in kernel-doc to ignore __aligned(SOMETHING) in structs. With this change, we can use integers OR sizeof() or macros as we please.

2013-02-22depmod: pass -P $CONFIG_SYMBOL_PREFIXJames Hogan1-3/+23
On architectures which have symbol prefixes, depmod emits lots of warnings like this: WARNING: $module.ko needs unknown symbol $symbol This is because depmod isn't being passed the -P <symbol_prefix> arguments to specify the symbol prefix to ignore. This option is included since the 3.13 release of module-init-tools. Update scripts/depmod.sh to take extra arguments for the symbol prefix (required but may be empty), and update the main Makefile to always pass "$(CONFIG_SYMBOL_PREFIX)" to scripts/depmod.sh. If the provided symbol prefix is non-empty, scripts/depmod.sh checks if depmod --version reports module-init-tools with a version number < 3.13 otherwise it appends -P $SYMBOL_PREFIX to the depmod command line.

2013-02-22kbuild: Fix destination-y for installed headersJesper Nilsson1-3/+3
Commit 10b63956fce7f369cc37fd4d994f09bd5203efe4 which plumbed in UAPI broke the destination-y functionality of scripts/Makefile.headersinst. The variable destination-y is used in a := assignment and so is expanded at declaration time, and the include of the Kbuild fragments that set destination-y to something is after this time, so it now always expands empty. There are no in-tree users of destination-y, but it allows any Kbuild-fragment to redirect where headers are installed. Just move the assignment of the variable that uses it below the include of the Kbuild fragment.

2013-02-22kbuild: clear KBUILD_SRC when calling 'make' in RPM specDavid R. Bild1-1/+1
'make rpm-pkg' and 'make binrpm-pkg' fail when the kernel source is read-only. Specifically, when the RPM spec generated by scripts/package/mkspec is run, KBUILD_SRC happens to be set to the source location and thus the invocation of 'make headers_install' fails when an internal call to 'filechk' tries to write a file into the source tree. The fix is to clear KBUILD_SRC for the 'make headers_install' invocation in the spec file, as is already done for the 'make modules_install' invocation. Signed-off-by: David R.

2013-02-19kbuild: Fix missing '\n' for NEW symbols in yes "" | make oldconfig >conf.newBen Hutchings1-1/+6
According to Documentation/kbuild/kconfig.txt, the commands: yes "" | make oldconfig >conf.new grep "(NEW)" conf.new should list the new config symbols with their default values. However, currently there is no line break after each new symbol. When kconfig is interactive the user will type a new-line at this point, but when non-interactive kconfig must print it.

2013-02-14scripts/sortextable: silence script outputArnd Bergmann1-1/+1
The exception table sorter outputs one line every time it gets called, e.g. 'sort done marker at 66dc00', which is slightly annoying when doing 'make -s' which is otherwise completely silent. Since that output is not helpful to most people building the kernel, turn it off by default. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: David Daney <david.daney@cavium.com> Cc: "H.

2013-02-13kbuild: limit dtc+cpp include pathStephen Warren1-2/+6
Device tree source files may now include header files. The intent is that those header files define/name constants used as part of the DT bindings. Currently this feature is open to abuse, since any kernel header file at all can be included, This could allow device tree files to become dependant on kernel headers files, and thus make them no longer OS-independent. This would also prevent separating the device tree source files from the kernel repository. Solve this by limiting the cpp include path for device tree files to separate directories.

2013-02-05checkpatch: fix $Float creation of match variablesJoe Perches1-5/+5
Commit 74349bccedb3 ("checkpatch: add support for floating point constants") added an unnecessary match variable that caused tests that used a $Constant or $LvalOrFunc to have one too many matches. This causes problems with usleep_range, min/max and other extended tests. Avoid using match variables in $Float. Avoid using match variables in $Assignment too.
