build failure with current linus tree

[JONGMAN HEO]

With current linus git (commit a25a2b84), I got following build error,

arch/x86/kernel/vm86_32.c: In function ??do_sys_vm86??:
arch/x86/kernel/vm86_32.c:340: error: implicit declaration of function ??__audit_syscall_exit??
make[3]: *** [arch/x86/kernel/vm86_32.o] Error 1

I do not have CONFIG_AUDITSYSCALL in my .config.

Regards,
Jongman.

Um... OK, I can reproduce it (32bit allmodconfig with AUDIT=y, AUDITSYSCALL=n)
Crap... It's "Audit: push audit success and retcode into arch ptrace.h".
