From: Arnd Bergmann arnd@arndb.de
Building with 'make W=1' reveals two function definitions without a previous prototype in the audit code:
lib/compat_audit.c:32:5: error: no previous prototype for 'audit_classify_compat_syscall' [-Werror=missing-prototypes] kernel/audit.c:1813:14: error: no previous prototype for 'audit_serial' [-Werror=missing-prototypes]
The first one needs a declaration from linux/audit.h but cannot include that header without causing conflicting (compat) syscall number definitions, so move the it into linux/audit_arch.h.
The second one is declared conditionally based on CONFIG_AUDITSYSCALL but needed as a local function even when that option is disabled, so move the declaration out of the #ifdef block.
