Correct.  Before, you had to have CONFIG_SECURITY enabled just to get 
the same capability support that you had by default in 2.4.  They've 
since moved that out of the dependence on LSM and made it supported by 
default, as it should have been from the beginning.  mmap_min_addr also 
required CONFIG_SECURITY until recently.
