* get_maintainer: allow keywords to match filenamesStephen Warren2013-02-271-0/+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.

* scripts/kernel-doc: handle struct member __aligned without numbersNishanth Menon2013-02-271-1/+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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ARC relocatable object files contain one/more .gnu.linkonce.arcextmap.* sections (collated by kernel/vmlinux.lds into .arcextmap in final link). 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 !

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.

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.

* | misc: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
