Subject: [PATCH] Revert "kernel/vm: Remove an obsolete comment."

This reverts commit 1db0961121bdb8145fe368fdca0205ddef354729.

It turns out the comment is not obsolete; what it refers to isn't
PAE systems but true 32-bit ones. I'm not sure we should use
64-bit cache offsets even there, but that's a decision for another
time.
