>Description:
Debian ABI tracking tools detected a possible problem with libkvm. It appears that these two symbols which are ment to be private are actually being exported:

# for i in _kvm_dpcpu_initialized _kvm_dpcpu_validaddr ; do nm -D /lib/libkvm.so.0 | grep $i ; done
0000000000004e20 T _kvm_dpcpu_initialized
0000000000004b60 T _kvm_dpcpu_validaddr

(I've reproduced this with FreeBSD 9.0-RC3 binaries as well)
