[PATCH] audit: fix broken class-based syscall audit
The sanity check in audit_match_class() is wrong. We are able to audit 2048 syscalls but in audit_match_class() we were accidentally using sizeof(_u32) instead of number of bits in _u32 when deciding how many syscalls were valid. On ia64 in particular we were hitting syscall numbers over the (wrong) limit of 256. Fixing the audit_match_class check takes care of the problem.
