Export mmap_min_addr and security_mmap_addr() to allow
kernel modules to use them.

Can other folks comment whether this should be EXPORT_SYMBOL or 
EXPORT_SYMBOL_GPL ?

I'm not sure whether this should be EXPORT_SYMBOL or EXPORT_SYMBOL_GPL, as
this hook was added in 2009, well after EXPORT_SYMBOL_GPL came into being.

Most of the LSM hooks are marked EXPORT_SYMBOL because they were part of
an existing interface when EXPORT_SYMBOL_GPL was introduced, IIRC.

What do folks think?

 ?That's right, This change is for outside kernel tree modules.

We don't export symbols not used by in-tree modules.
Which in-tree module needs to access these symbols?
