2013-02-22coccicheck: Allow to show the executed command lineBernd Schubert
On my system one of the tests failed with "Fatal error: exception Failure("No OCaml compiler found! Install either ocamlopt or ocamlopt.opt")". Investigating such issues is easier if the executed command line is being shown.

This patch allows the use of setlocalversion script regardless of the language parameters. Otherwise, the `svn info 2>/dev/null | grep '^Last Changed Rev'` returns nothing because for instance, in French the text 'Last Changed Rev' is replaced by 'Révision de la dernière modification' Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Michal Marek <mmarek@suse.cz>
2013-02-22depmod: pass -P $CONFIG_SYMBOL_PREFIXJames Hogan
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 Nilsson
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. Bild
'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.

2013-02-13kbuild: limit dtc+cpp include pathStephen Warren
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.

2013-01-22lib: devres: Introduce devm_ioremap_resource()Thierry Reding
The devm_request_and_ioremap() function is very useful and helps avoid a whole lot of boilerplate. However, one issue that keeps popping up is its lack of a specific error code to determine which of the steps that it performs failed. Furthermore, while the function gives an example and suggests what error code to return on failure, a wide variety of error codes are used throughout the tree. In an attempt to fix these problems, this patch adds a new function that drivers can transition to. The devm_ioremap_resource() returns a pointer to the remapped I/O memory on success or an ERR_PTR() encoded error code on failure. Callers can check for failure using IS_ERR() and determine its cause by extracting the error code using PTR_ERR(). devm_request_and_ioremap() is implemented as a wrapper around the new API and return NULL on failure as before. This ensures that backwards compatibility is maintained until all users have been converted to the new API, at which point the old devm_request_and_ioremap() function should be removed. A semantic patch is included which can be used to convert from the old devm_request_and_ioremap() API to the new devm_ioremap_resource() API. Some non-trivial cases may require manual intervention, though.

This section is used by debuggers to display the extension instructions and need-not be loaded by target (hence !SHF_ALLOC) The final kernel binary only needs .arcextmap entry in modpost's ignore list (section_white_list[]). However when building modules, modpost scans each object file individually, hence tripping on non-aggregated .gnu.linkonce.arcextmap.* entries as well. Thus need for the 2 entires !

2013-01-03misc: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the last of the __dev* markings from the kernel from a variety of different, tiny, places. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

Commit 56c176c9cac9 ("UAPI: strip the _UAPI prefix from header guards during header installation") strips the _UAPI prefix from header guards, but only if there's a single space between the cpp directive and the label.
