Subject: [RFC][PATCH -tip] x86: audit.c remove unnecessary global arrays


ia32_dir_class[], ia32_write_class[], ia32_read_class[], ia32_chattr_class[]
and ia32_signal_class[] are used only by arch/x86/kernel/audit_64.c
which can be replace by local variables:

dir_class[], write_class[], read_class[], chattr_class[] and signal_class[]
