I've noticed a "off by one" error in /proc/<pid>/mmap: In the ranges
the "to-address" is to high by one. The result is something like
It should be

Also the current system call interface to the memory statistics does
not return the size of the "page cache". You can see this if you look
into fs/proc/array, where /proc/meminfo is implemented. I had pointed
this out once before; the meminfo system call (I can't remember it's
name right now) returns a structure that should be either expanded to
include the page_cache, or the page_cache should be added to the
buffers (which is worse in my opinion).

I'd also suggest to add a paragraph to the README that explains how
to (cross-)compile an a.out kernel on an ELF system. I configured it
correctly, and the Makefile in arch/i386 seems to take care of the
configuration variables, but it did not work:

An undefined symbol "_start" and about three (sorry, no typescript)
other undefined symbols when linking. I need a newer kernel for a
tiny a.out system.
