svn commit: r273166 - head/lib/libkvm

New Revision: 273166
URL: https://svnweb.freebsd.org/changeset/base/273166

Log:
  Fix the type of pte_pa as when it is passed into _kvm_pa2off it is either
  a uint64_t or a pointer to an off_t. With it being a u_long can result in
  incorrect values being returned.
