New Revision: 326384
URL: https://svnweb.freebsd.org/changeset/base/326384
Log:
Use const pointers to avoid casting away constness.
The host_open interface was a legitimate mismatch to the userboot
function, while the other pointers didn't need to be non-const.
This makes the powerpc warning free again.
