commit 6f25517010dd ("entry: Rework syscall_audit_enter()") relies on
dead code elimination to remove the call to syscall_enter_audit() when
CONFIG_AUDITSYSCALL is disabled. However, with s390 GCC 13.4.0 +
CONFIG_KASAN, audit_context() is not inlined despite being marked
inline, causing an undefined reference to syscall_enter_audit().Force audit_context() to be __always_inline to ensure the conditional can be constant-folded and dead code elimination works correctly.
