Here's all the hooks converted over to function calls. Chris Wright
pointed out I need to do some extra work with the existing capabilities
hooks, but I'll do that in the morning.
Thanks to John Levon for pointing out cond_syscall() to me, very cool
function. That removes the need to have a sys_security.c file.
Patch is against 2.5.43, and builds for me, both with and without
CONFIG_SECURITY set. Haven't booted it yet though...
thanks,
greg k-h
