lib/audit.c provides a generic function for auditing system calls. This patch extends it for compat syscall support on bi-architectures (32/64-bit) by adding lib/compat_audit.c. What is required to support this feature are: * add asm/unistd32.h for compat system call names * select CONFIG_AUDIT_ARCH_COMPAT_GENERIC Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Acked-by: Richard Guy Briggs <rgb@redhat.com> Signed-off-by: Eric Paris <eparis@redhat.com>
