If anyone has any objections, please let me know. ------------------ From: Josh Poimboeuf [ Upstream commit 09f37f2d7b21ff35b8b533f9ab8cfad2fe8f72f6 ] sched_smt_active() can be called from noinstr code, so it should always be inlined. The CONFIG_SCHED_SMT version already has __always_inline. Do the same for its !CONFIG_SCHED_SMT counterpart. Fixes the following warning: vmlinux.o: error: objtool: intel_idle_ibrs+0x13: call to sched_smt_active() leaves .noinstr.text section Fixes: 321a874a7ef8 ("sched/smt: Expose sched_smt_present static key") Reported-by: kernel test robot Signed-off-by: Josh Poimboeuf Signed-off-by: Ingo Molnar Cc: Linus Torvalds Link: https://lore.kernel.org/r/1d03907b0a247cf7fb5c1d518de378864f603060.1743481539.git.jpoimboe@kernel.org Closes: https://lore.kernel.org/r/202503311434.lyw2Tveh-lkp@intel.com/ Signed-off-by: Sasha Levin --- include/linux/sched/smt.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/sched/smt.h b/include/linux/sched/smt.h index 59d3736c454cf..737b50f40137b 100644 --- a/include/linux/sched/smt.h +++ b/include/linux/sched/smt.h @@ -12,7 +12,7 @@ static __always_inline bool sched_smt_active(void) return static_branch_likely(&sched_smt_present); } #else -static inline bool sched_smt_active(void) { return false; } +static __always_inline bool sched_smt_active(void) { return false; } #endif void arch_smt_update(void); -- 2.39.5
