There also is 6627406 "mdb memstat showed mess for freelist in snv76 hvm domU.",
which appears to be a duplicate of 6174625, but has an engineer assigned, 
the fix is known, and the description already mentions the root cause of the bug.


I'm using this fix (note: freemem is defined as ulong_t, so the correct
printf format is %lu):


fix ::memstat freelist output when running under 32-bit
