[PATCH] sparc64 audit syscall classes hookup
... that should do it for all targets; the only remaining issues are mips (currently treated as non-biarch) and handling of other OS emulations (OSF/SunOS/Solaris/???). The latter would need to be assigned new AUDIT_ARCH_... ABI numbers anyway... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
