2016-05-20checkpatch: improve --git <commit-count> shortcutJoe Perches
The --git <commit-count> shortcut can be confused by a tag with a dash like v4.4-rc1. Improve the test to verify the <commit-count> expression ends with a dash followed by a numeric value. Improve the git log result to verify the "<sha1> <subject>" output as well.

2016-05-20checkpatch: reduce number of `git log` calls with --gitJoe Perches
checkpatch currently calls git log multiple times to first get the <revision range> sha1 values and again to get the subject for each individual sha1 commit. Always get the sha1 and subject at the same time instead. Store the subject in a sha1 hash to avoid the second git log exec.

2016-05-05modpost: fix module autoloading for OF devices with generic compatible propertyPhilipp Zabel
Since the wildcard at the end of OF module aliases is gone, autoloading of modules that don't match a device's last (most generic) compatible value fails. For example the CODA960 VPU on i.MX6Q has the SoC specific compatible "fsl,imx6q-vpu" and the generic compatible "cnm,coda960". Since the driver currently only works with knowledge about the SoC specific integration, it doesn't list "cnm,cod960" in the module device table. This results in the device compatible "of:NvpuT<NULL>Cfsl,imx6q-vpuCcnm,coda960" not matching the module alias "of:N*T*Cfsl,imx6q-vpu" anymore, whereas before commit 2f632369ab79 ("modpost: don't add a trailing wildcard for OF module aliases") it matched the module alias "of:N*T*Cfsl,imx6q-vpu*". This patch adds two module aliases for each compatible, one without the wildcard and one with "C*" appended. $ modinfo coda | grep imx6q alias: of:N*T*Cfsl,imx6q-vpuC* alias: of:N*T*Cfsl,imx6q-vpu Fixes: 2f632369ab79 ("modpost: don't add a trailing wildcard for OF module aliases") Link: http://lkml.kernel.org/r/1462203339-15340-1-git-send-email-p.zabel@pengutronix.de Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Cc: Javier Martinez Canillas <javier@osg.samsung.com> Cc: Brian Norris <computersforpeace@gmail.com> Cc: Sjoerd Simons <sjoerd.simons@collabora.co.uk> Cc: Rusty Russell <rusty@rustcorp.com.au> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: <stable@vger.kernel.org> [4.5+] Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

Also recognize standalone "prompt". Before this patch we incorrectly identified some symbols as not having a prompt and potentially needing to be selected by something else. Note that this patch could theoretically change the resulting .config, causing it to have fewer symbols turned on. However, given the current set of Kconfig files, this situation does not occur because the symbols newly added to %prompts are absent from %selects.

2016-04-26localmodconfig: Reset certificate pathsBenjamin Poirier
When using `make localmodconfig` and friends, if the input config comes from a kernel that was built in a different environment (for example, the canonical case of using localmodconfig to trim a distribution kernel config) the key files for module signature checking will not be available and should be regenerated or omitted. Otherwise, the user will be faced with annoying errors when trying to build with the generated .config: make[1]: *** No rule to make target 'keyring.crt', needed by 'certs/x509_certificate_list'. Stop.

2016-04-26localmodconfig: Add missing $ to reference a variableBenjamin Poirier
That is clearly what the original intention was. This does not change the output .config but it prevents some useless processing. ! eq "m" is changed to the simpler eq "y"; symbols with values other than m|y are not included in %orig_configs.

2016-04-26localmodconfig: Fix parsing of "help" textBenjamin Poirier
Help text may start with "help" or "---help---". This patch fixes read_kconfig() to recognize the second variant. This removes useless junk from %depends and %selects. That junk is due to help text that contains the words "selects" and "depends".

2016-04-12debugfs, coccinelle: check for obsolete DEFINE_SIMPLE_ATTRIBUTE() usageNicolai Stange
In order to protect against file removal races, debugfs files created via debugfs_create_file() now get wrapped by a struct file_operations at their opening. If the original struct file_operations are known to be safe against removal races by themselves already, the proxy creation may be bypassed by creating the files through debugfs_create_file_unsafe(). In order to help debugfs users who use the common DEFINE_SIMPLE_ATTRIBUTE() + debugfs_create_file() idiom to transition to removal safe struct file_operations, the helper macro DEFINE_DEBUGFS_ATTRIBUTE() has been introduced. Thus, the preferred strategy is to use DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe() now. Introduce a Coccinelle script that searches for DEFINE_SIMPLE_ATTRIBUTE()-defined struct file_operations handed into debugfs_create_file(). Suggest to turn these usages into the DEFINE_DEBUGFS_ATTRIBUTE() + debugfs_create_file_unsafe() pattern.

Now that we no longer emit .stubs symbols into a section VMA loaded at absolute address 0x1000, we can drop the ARM-specific override that sets a lower limit based on CONFIG_PAGE_OFFSET, below which symbols are filtered from the kallsyms output.

2016-04-07ARM: 8555/1: kallsyms: ignore ARM mode switching veneersArd Biesheuvel
On ARM, the linker may emit veneers to deal with relative branch instructions that appear too far away from their targets. Since the second kallsyms pass results in an increase of the kernel size, it may result in additional veneers to be emitted, potentially affecting the output of kallsyms itself if these symbols are visible to it, and for that reason, symbols whose names end in '_veneer' are ignored explicitly. However, when building Thumb2 kernels, such veneers are named differently if they also incur a mode switch, and since they are not filtered by kallsyms, they may cause the build to fail. So filter symbols whose names end in '_from_arm' or '_from_thumb' as well.
