Linus Torvalds 5a658afd46 Objtool changes for v6.15: ... - The biggest change is the new option to automatically fail the build on objtool warnings: CONFIG_OBJTOOL_WERROR. While there are no currently known unfixed false positives left, such an expansion in the severity of objtool warnings inevitably creates a risk of build failures, so it's disabled by default and depends on !COMPILE_TEST, so it shouldn't be enabled on allyesconfig/allmodconfig builds and won't be forced on people who just accept build-time defaults in 'make oldconfig'. While the option is strongly recommended, only people who enable it explicitly should see it. (Josh Poimboeuf) - Disable branch profiling in noinstr code with a broad brush that includes all of arch/x86/ and kernel/sched/. (Josh Poimboeuf) - Create backup object files on objtool errors and print exact objtool arguments to make failure analysis easier (Josh Poimboeuf) - Improve noreturn handling (Josh Poimboeuf) - Improve rodata handling (Tiezhu Yang) - Support jump tables, switch tables and goto tables on LoongArch (Tiezhu Yang) - Misc cleanups and fixes (Josh Poimboeuf, David Engraf, Ingo Molnar) Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAmfefkARHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1inlRAAvd9Hom2qh9Iu+KYYF58vsg9zsxWZA6I1 blouKI4SUA8Xjuw6Nihx+emaPaMW1boGSLTNsFzrCa3S1+4UHTTp/Y8snZWJ/Mc/ Peg52N6u/LIcoQM+vNJYRtd9y4wabX87vl0qTxte0kB0Neps3/yQvxtUa2K1srXp 8nwHK+PdzNsgPuIrIiNc9ymsPvbqFHmVIRRVNVKX4BlPJi2kJs9kx43kszweQR/X kW/bs1315m1HS5i02K0Zs/XdOZHLsk9ERu+aviBJV1txrgZIukATIqbODiI+3RZX 0oa3KxfzEVFN2k3OukrezV2INzETkN+oOSTAZIUOqwSVe+8rdQVBSdYT6svYn/yy aS8Bi5Mm1nfizTU+cRrzU7FxWCmwsxm9r4fHPTV8Owjxg0uoGk/E/qlvERuR2rpA p2tHMo1lp2Yo+VZBZPfm5KDHFG4tSGhF9eav2bqSI7/Kf5AWxRl8kBs5iLrcxsXh 4qk3FalnuM7A+1McAUcBJAvM897Yie0s2G83ZipyYyA6U3LSBhBMWh9FlIiAjuIh YnX6IFkW9tVzVZpJFEGQn+2Ewl5Y2Go5bokKk03vkWCZCgg+hEUsVh6Cnm1ocZpO Ll3/UF4i8XjjyuAuHDn6mzyHIgch2xRN02v7dJSb09+O9b8vIoPoSqbWSLJUOBqf r6UesXDG8mY= =iswJ -----END PGP SIGNATURE----- Merge tag 'objtool-core-2025-03-22' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull objtool updates from Ingo Molnar: - The biggest change is the new option to automatically fail the build on objtool warnings: CONFIG_OBJTOOL_WERROR.
