=======
NOTE 1
As long as sizeof(int)==sizeof(long) there are no real impact of
inconsistency between (long) int format and int arg (or vice versa),
but it is better to have clean code ...
=======
The warnings in kvm_getswapinfo.c points to real error, because
longlongs really cannot be succesfully printed as ints (but it shouldn't
abend as of sizeof(int)<sizeof(long long)). It's the reason
I assign medium priority to this PR
