Conform the layout, informational and status messages to TAP. No
functional change is intended other than the layout of output messages.

Hi,

When validate_lower_address_hint() returns 1, it implies that despite 
filling the lower

range, mmap succeeded. IMHO, ksft_exit_fail_msg() should be used 
instead, with a

more descriptive message indicating that the memory was unexpectedly 
allocated.

Can you fire up a patch for this? Otherwise I'll get back to it next week.
