2017-03-01objtool, modules: Discard objtool annotation sections for modulesJosh Poimboeuf2-1/+5
The '__unreachable' and '__func_stack_frame_non_standard' sections are only used at compile time. They're discarded for vmlinux but they should also be discarded for modules. Since this is a recurring pattern, prefix the section names with ".discard.". It's a nice convention and vmlinux.lds.h already discards such sections. Also remove the 'a' (allocatable) flag from the __unreachable section since it doesn't make sense for a discarded section.

2017-02-27checkpatch: warn when formats use %Z and suggest %zAlexey Dobriyan1-9/+20
vsnprintf extension %Z<foo> is non-standard C. Suggest the use of %z instead. Miscellanea: - Correct the misuse of type string PRINTF_0xDECIMAL type strings are supposed to be uppercase only. Fix this and add tr/[a-z]/[A-Z] to the type check in case I forget this again sometime in the future. - Improve the mechanism to find these defects so all 3 current checks are done on the format string [joe@perches.com: correct the misuse of type string PRINTF_0xDECIMAL, improve the mechanism to find these defects] Link: http://lkml.kernel.org/r/4e3ad74b0c9dc229b06018a2d79655308ddbbebd.1484014173.git.joe@perches.com Link: http://lkml.kernel.org/r/20170109235955.GA6787@avx2 Signed-off-by: Alexey Dobriyan <adobriyan@gmail.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2017-02-27scripts/spelling.txt: add some typo-wordsJinbum Park1-0/+3
I wrote a simple script to find new typo not in spelling.txt. (https://github.com/jinb-park/find-linux-kernel-typo) and get following result: [ rank ] 63 paramaters 18 alignement 9 strucuture .... The number means how many files include the typo. This patch adds these common typo.

2017-02-24checkpatch: remove false unbalanced braces warningSven Eckelmann1-2/+2
Lines containing "} else {" should not be detected as unbalanced braces. But the second check can be reduced to ".+else\s*{" and it therefore never checked if the beginning of a line contains any other character (like the relevant "}"). This check would also return true for "} else {" and create warnings like CHECK: Unbalanced braces around else statement #391: FILE: ./net/batman-adv/tvlv.c:391: + } else { The check can be changed to check the whole line for the missing "}" to avoid this false positive.

Embedded function names are less appropriate to use when refactoring can cause function renaming. Prefer the use of "%s", __func__ to embedded function names.

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux Pull powerpc updates from Michael Ellerman: "Highlights include: - Support for direct mapped LPC on POWER9, giving Linux direct access to devices that may be on there such as a UART. - Memory hotplug support for the Power9 Radix MMU. - Add new AUX vectors describing the processor's cache geometry, to be used by glibc. - The ability for a guest to ask the hypervisor to resize the guest's hash table, and in addition support for doing so automatically when memory is hotplugged into/out-of the guest. This allows the hash table to be sized based on the current memory usage of the guest, rather than the maximum possible memory usage. - Implementation of optprobes (kprobe optimisation) for powerpc. In addition there's the topic branch shared with the KVM tree, which includes support for guests to use the Radix MMU on Power9.
