Do not depend nor use anything from the calling code (do not take
anything from git). If it has to serve as compatibility wrapper to
mmap, it better should be mmap(2): return MAP_FAILED if error, do not
exit process, do no output. I wouldn't expect open(2) to print "File
not found", would you?

Besides, MAP_FAILED is perfectly handled in calling layers. If they
even print out errno, the case is completely covered and simplier
handled.
