In case MAP_FAILED is currently the expected return value on all 
architectures, then this should be expected by the test. When will there 
be a proper mmap() implementation exist? What is a proper mmap() 
implementation for RTEMS at all?

I used mmap() on some GUI library to speed up the font initialization 
and simply mapped read-only font files (IMFS memfiles) via mmap(). It 
would be good to gather some use cases. I think Qt uses also mmap() for 
font files.
