1) I'm not sure the "no-op if CONFIG_CSA not set" comments
   are worthwhile - it does not seem to be a common practice
   to mark macros that collapse under certain CONFIG's with
   such comments, and some code, such as in fork.c, would
   become quite a bit less readable if such comments were
   widely used.

Yeah, that makes sense. Will be fixed in next posting.


2) Three of the added csa_update_integrals() lines have leading spaces, instead of a tab char, such as in:

}

Caused by 'cut-n-paste'. Will be fixed.

3) Is it always the case that csa_update_integrals() and
update_mem_hiwater() are used together? If so, perhaps
they could be collapsed into one? Even the current->mm
test inside them could be made one test, perhaps?

As Robin pointed out, there are a couple of instances that are not the case. Actually there are three.

Thanks for your feedback, Paul!
