* kbuild: dtbinst: remove unnecessary __dtbs_install_prep targetMasahiro Yamada2017-05-081-8/+0
| | | | | | | | | | Since commit 5399eb9b3908 ("dtbsinstall: don't move target directory out of the way"), the target __dtbs_install_prep is invoked just for creating the install directory, but all the necessary directories are automatically created by: cmd_dtb_install = mkdir -p $(2); cp $< $(2) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

* kbuild: drop -Wno-unknown-warning-option from clang optionsMasahiro Yamada2017-04-231-1/+0
| | | | | | | | | | | | | | | Since commit c3f0d0bc5b01 ("kbuild, LLVMLinux: Add -Werror to cc-option to support clang"), cc-option and friends work nicely for clang. However, -Wno-unknown-warning-option makes clang happy with any unknown warning options even if -Werror is specified. Once -Wno-unknown-warning-option is added, any succeeding call of cc-disable-warning is evaluated positive, then unknown warning options are accepted. This should be dropped.

* kbuild: fix asm-offset generation to work with clangJeroen Hofstee2017-04-231-2/+6

* kbuild: consolidate redundant sed script ASM offset generationMasahiro Yamada2017-04-231-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This part ended up in redundant code after touched by multiple people. [1] Commit 3234282f33b2 ("x86, asm: Fix CFI macro invocations to deal with shortcomings in gas") added parentheses for defined expressions to support old gas for x86. [2] Commit a22dcdb0032c ("x86, asm: Fix ancient-GAS workaround") split the pattern into two to avoid parentheses for non-numeric expressions. [3] Commit 95a2f6f72d37 ("Partially revert patch that encloses asm-offset.h numbers in brackets") removed parentheses from numeric expressions as well because parentheses in MN10300 assembly have a special meaning (pointer access). Apparently, there is a conflict between [1] and [3]. After all, [3] took precedence, and a long time has passed since then. Now, merge the two patterns again because the first one is covered by the other. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Reviewed-by: Matthias Kaehlcke <mka@chromium.org>

* | objtool, modules: Discard objtool annotation sections for modulesJosh Poimboeuf2017-03-012-1/+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.

I fixed "_aligment_handler" in arch/openrisc/kernel/entry.S because it is surrounded by #if 0 ... #endif. It is surely safe and I confirmed "_alignment_handler" is correct. I also fixed the "controler" I found in the same hunk in arch/openrisc/kernel/head.S.

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.
