The FSF address check is a bit too verbose looking for the GPL text. Quiet it a bit by requiring --strict for the GPL bit. Also make the address tests match a few uses of abbreviations for street names and make it case insensitive. Signed-off-by:

If statements don't need multiple parentheses around tested comparisons like "if ((foo == bar))". An == comparison maybe a sign of an intended assignment, so emit a slightly different message if so. Signed-off-by:

This test should remove all the spaces before a tab not just one space. Substitute a tab for each 8 space block before a tab and remove less than 8 spaces before a tab. This SPACE_BEFORE_TAB test is done after CODE_INDENT. If there are spaces used at the beginning of a line that should be converted to tabs, please make sure that the CODE_INDENT test and conversion is done before this SPACE_BEFORE_TAB test and conversion.

switch case statements missing a break statement are an unfortunately common error. e.g.: commit 4a2c94c9 ("HID: kye: Add report fixup for Genius Manticore Keyboard") case blocks should end in a break/return/goto/continue. If a fall-through is used, it should have a comment showing that it is intentional. Ideally that comment should be something like: "/* fall-through */" Add a test to look for missing break statements. This looks only at the context lines before an inserted case so it's possible to have false positives when the context contains a close brace and the break is before the brace and not part of the patch context. Looking at recent patches, this is a pretty rare occurrence. The normal kernel style uses a break as the last line of the previous block. Signed-off-by:

The current checkpatch test for split strings does not find several cases that should be found. For instance: /* Else poor success; go back to mode in "active" table */ } else { IWL_DEBUG_RATE(mvm, - "LQ: GOING BACK TO THE OLD TABLE suc=%d cur-tpt=%d old-tpt=%d\n", + "GOING BACK TO THE OLD TABLE: SR %d " + "cur-tpt %d old-tpt %d\n", window->success_ratio, window->average_tpt, lq_sta->last_tpt); does not currently emit a warning. Improve the test to find these cases. Add more exceptions to reduce false positives for assembly and octal/hex string constants. Signed-off-by: -

This patch makes a couple of changes to the SMBIOS/DMI scanning code so it can be used on other archs (such as ARM and arm64): (a) wrap the calls to ioremap()/iounmap(), this allows the use of a flavor of ioremap() more suitable for random unaligned access; (b) allow the non-EFI fallback probe into hardcoded physical address 0xF0000 to be disabled.

To help avoid an architecture failing to correctly check kernel/user boundaries when handling copy_to_user, copy_from_user, put_user, or get_user, perform some simple tests and fail to load if any of them behave unexpectedly. Specifically, this is to make sure there is a way to notice if things like what was fixed in commit 8404663f ("ARM: 7527/1: uaccess: explicitly check __user pointer when !CPU_USE_DOMAINS") ever regresses again, for any architecture. Additionally, adds new "user" selftest target, which loads this module. Signed-off-by:

This is a pair of test modules I'd like to see in the tree. Instead of putting these in lkdtm, where I've been adding various tests that trigger crashes, these don't make sense there since they need to be either distinctly separate, or their pass/fail state don't need to crash the machine. These live in lib/ for now, along with a few other in-kernel test modules, and use the slightly more common "test_" naming convention, instead of "test-". We should likely standardize on the former: $ find . -name 'test_*.c' | grep -v /tools/ | wc -l 4 $ find . -name 'test-*.c' | grep -v /tools/ | wc -l 2 The first is entirely a no-op module, designed to allow simple testing of the module loading and verification interface. It's useful to have a module that has no other uses or dependencies so it can be reliably used for just testing module loading and verification. The second is a module that exercises the user memory access functions, in an effort to make sure that we can quickly catch any regressions in boundary checking (e.g. like what was recently fixed on ARM). This patch (of 2): When doing module loading verification tests (for example, with module signing, or LSM hooks), it is very handy to have a module that can be built on all systems under test, isn't auto-loaded at boot, and has no device or similar dependencies. This creates the "test_module.ko" module for that purpose, which only reports its load and unload to printk. Signed-off-by:

get_maintainer currently uses "Signed-off-by" style lines to find interested parties to send patches to when the MAINTAINERS file does not have a specific section entry with a matching file pattern. Add statistics for commit authors and lines added and deleted to the information provided by --rolestats. These statistics are also emitted whenever --rolestats and --git are selected even when there is a specified maintainer. This can have the effect of expanding the number of people that are shown as possible "maintainers" of a particular file because "authors", "added_lines", and "removed_lines" are also used as criterion for the --max-maintainers option separate from the "commit_signers". The first "--git-max-maintainers" values of each criterion are emitted. Any "ties" are not shown. For example: (forcedeth does not have a named maintainer) Old output: $ ./scripts/get_maintainer.pl -f drivers/net/ethernet/nvidia/forcedeth.c "David S.

Add #include <linux/cache.h> to define __read_mostly. Convert cache.h to use uapi/linux/kernel.h instead of linux/kernel.h to avoid recursive #includes. Convert the ALIGN macro to __ALIGN_KERNEL. printk_once only sets the bool variable tested once so mark it __read_mostly. Neaten the alignment so it matches the rest of the pr_<level>_once #defines too. Signed-off-by:

"make headers_check" warns about soundcard.h for (at least) five years now: [...]/usr/include/linux/soundcard.h:1054: userspace cannot reference function or variable defined in the kernel We're apparently stuck with providing OSSlib-3.8 compatibility, so let's special case this declaration just to silence it. Notes: 0) Support for OSSlib post 3.8 was already removed in commit 43a99076 ("sound: Remove OSSlib stuff from linux/soundcard.h"). Five years have passed since that commit: do people still care about OSSlib-3.8? If not, quite a bit of code could be remove from soundcard.h (and probably ultrasound.h). 2) By the way, what is actually meant by: It is no longer possible to actually link against OSSlib with this header, but we still provide these macros for programs using them. Doesn't that mean compatibility to OSSlib isn't even useful? 3) Anyhow, a previous discussion soundcard.h, which led to that commit, starts at https://lkml.org/lkml/2009/1/20/349 . 4) And, yes, I sneaked in a whitespace fix.
