Back out a portion of the last commit. DFLTPHYS and MAXPHYS cannot
be set by a kernel conf option due to the struct buf structural dependancy (sizing of b_pages[]) creating a conflict with modules (which are not compiled with kernel config options overrides). We'll be able to sysctl these two later on when the buffer subsystem is revamped.
