However, with CONFIG_LTO_CLANG, TEXT_MAIN becomes\n\".text .text.[0-9a-zA-Z_]*\" which wrongly matches also the thunk\nsections. The output layout is then different than expected. For\ninstance, the currently defined range [__indirect_thunk_start,\n__indirect_thunk_end] becomes empty.\n\nPrevent the problem by using \"..\" as the first separator, for example,\n\".text..__x86.indirect_thunk\". This pattern is utilized by other\nexplicit section names which start with one of the standard prefixes,\nsuch as \".text\" or \".data\", and that need to be individually selected in\nthe linker script.\n\nFixes: dc5723b02e52 (\"kbuild: add support for Clang LTO\")\nSigned-off-by: Petr Pavlu <petr.pavlu@suse.com>\nSigned-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>\nLink: https://lore.kernel.org/r/20230711091952.27944-2-petr.pavlu@suse.com\n[nathan: Fix conflicts with SRSO and fold in fix issue brought up by Andrew\n         Cooper in post-review:\n         https://lore.kernel.org/20230803230323.1478869-1-andrew.cooper3@citrix.com/]\nSigned-off-by: Nathan Chancellor <nathan@kernel.org>","shortMessageHtmlLink":"x86/retpoline,kprobes: Fix position of thunk sections with CONFIG_LTO…"}},{"before":null,"after":"45c4fb6095d872785e077942da896d65d87ab56b","ref":"refs/heads/test_revert","pushedAt":"2023-05-15T22:02:00.511Z","pushType":"branch_creation","commitsCount":0,"pusher":{"login":"nickdesaulniers","name":"Nick Desaulniers (paternity leave)","path":"/nickdesaulniers","primaryAvatarUrl":"https://avatars.githubusercontent.com/u/1823839?s=80&v=4"},"commit":{"message":"TEST REVERT OF 88b61e3bff93f99712718db785b4aa0c1165f35c","shortMessageHtmlLink":"TEST REVERT OF <a class=\"commit-link\" data-hovercard-type=\"commit\" data-hovercard-url=\"https://github.com/ClangBuiltLinux/linux/commit/88b61e3bff93f99712718db785b4aa0c1165f35c/hovercard\" href=\"https://github.com/ClangBuiltLinux/linux/commit/88b61e3bff93f99712718db785b4aa0c1165f35c\"><tt>88b61e3</tt></a>"}}],"hasNextPage":false,"hasPreviousPage":false,"activityType":"all","actor":null,"timePeriod":"all","sort":"DESC","perPage":30,"cursor":"djE6ks8AAAADZ5uNXwA","startCursor":null,"endCursor":null}},"title":"Activity · ClangBuiltLinux/linux"}
