x86/orc: Make the is_callthunk() definition depend on CONFIG_BPF_JIT=y
Recent commit: 020126239b8f Revert "x86/orc: Make it callthunk aware" Made the only user of is_callthunk() depend on CONFIG_BPF_JIT=y, while the definition of the helper function is unconditional. Move is_callthunk() inside the #ifdef block. Addresses this build failure: arch/x86/kernel/callthunks.c:296:13: error: ‘is_callthunk’ defined but not used [-Werror=unused-function] Signed-off-by: Ingo Molnar <mingo@kernel.org> Cc: Josh Poimboeuf <jpoimboe@kernel.org> Cc: linux-kernel@vger.kernel.org Cc: Peter Zijlstra <peterz@infradead.org>
