Subject: [PATCH 1/1] additional ipsec audit patch

This patch disables auditing in ipsec when CONFIG_AUDITSYSCALL is
disabled in the kernel. 

This patch also includes a bug fix for xfrm_state.c as a result of
original ipsec audit patch.

Let me know if it looks ok.

My mail gateway has been acting crazy so I apologize for any
replicas being sent for ipsec audit patches.

regards,
Joy
