This patch fixes a case in increasing a memory reservation where you
do not get the pages nor do you get an error.  While an argument might
be made that checking the page count independently is workable, it
does seem reasonable to have the operation return a failure in the
cases where it doesn't do what was asked. Right now, it mostly returns
the correct status.  This patch just adds another instance of this.

And, while-I-was-there, I've been generating linker maps for qemu in
my own builds. It's harmless, until you need it and then it's valuable.
Tweak the Makefile to create the map.
