Ah... I did misunderstand you. I thought you meant CONFIG_MODULES in general,
which'd be okay - obviously, if module support is disabled, you can't load a
module anyway.

No, I wasn't planning to do that. I was thinking more along the lines of
adding another handler in to struct exec_domain, but that isn't especially
generic.

I think now that I'm probably best providing a generic pluggable syscall
handler, one that is very careful to make sure the syscall can't be entered
whilst the module is being unloaded.
